Title: Displacement transducer
Inventor: ONO YUTAKA
IPC: H03M1/24
Filed: 1986-03-19
Abstract: PURPOSE:To compensate an error of a code board due to eccentricity by providing a signal detection circuit taking the sum of output signals of original detection photodetectors of two photo sensors and the sum of output signals of angle detection photodetectors and eliminating the error between an origin signal and an angle signal due to the eccentricity of the code board. CONSTITUTION:The code board 2 is formed as a disk and slit strings 21-23 of three stages arranged concentrically are formed. A transmission slit of the medium stage slit string 22 is an angle detection slit and the outer slit string 21 and the inner slit string 23 are origin detection slits. Even when the code board is eccentric, a lead phase is detected by a photo diode 32 for angle detection of one photo sensor and a lagged phase is detected by a photo diode 32 for angle detection of the other photo sensor. Thus, the error due to eccentricity is cancelled by using the sensors differentially and the error of the angle signal due to eccentricity is compensated.

Abstract: PURPOSE:To stabilize an electrostatic charging potential and to obtain a high-quality image by providing an image carrier having a photoconductor which performs positive electrostatic charging, a scorotron type electrostatic charger and a transfer roller. CONSTITUTION:A photosensitive drum 4 is provided with a photoconductive layer 46 on an Al base body 45. The layer 46 is obtained by superposing a charge transportation layer 47, a charge generation layer 48 and an urethane/Si resin layer 49 on the Al base body 45. The drum 4 is stably electrostatically charged to be positive in s specified manner by the scorotron type electrostatic charger 52 with high accuracy and exposed through a gap 51. Light is cast to the layer 48 and a negative charge is generated. The generated positive charge is erased with the negative charge, and the positive charge flows to the base body 45 through the layer 47. Then, a part where the light is received becomes potential zero, and an electrostatic latent image is formed. The latent image is developed with the developer supplied by a roller 11. A conductive rubber roller 36 is electrostatically to be negative and electric field is generated between the drum 4 which is electrostatically charged to be positive and the roller 36 so as to transfer the image to a transfer material fed to a paper passing path 37. By adopting the transfer roller, O3 is restrained from being evolved and the image is stably supplied for a long time without clarifier.

Title: Insect proofing grain bag
Inventor: SANO KOJI
IPC: B65D30/02
Filed: 1989-03-16
Abstract: PURPOSE:To prevent entry into a grain bag of harmful insects such as rice weevils and hence the loss, contamination, degradation and rot of grain contained in the bag by providing the bag consisting of thermoplastic resin film and having air vent smaller than the grain and the harmful insects. CONSTITUTION:When an insect proofing grain bag consisting of thermoplastic resin film is filled with grain such as rice, wheat, etc. and then its opening is closed by heat sealing, etc., the entry of the harmful insects thereinto is prevented and the air passage is secured to retain the freshness of the grain in the bag and exert its function to improve mildewproofing, since the bag has air vent smaller than the grain and harmful insects such as rice weevil parasitic thereon. The harmful insects such as the rice weevils are also prevented from biting the bag to enlarge the air vent sufficiently to allow them to enter the bag. Due to this preventive measure of their inward entry, this bag also has the function to prevent the growth or multiplication of other grain vermin such as molds, ticks, etc. caused by the excrements from the rice weevils, thereby precluding the degradation and rot of the grain.

Title: Heat exchanger
Inventor: TANAKA HIROYOSHI
IPC: F28F1/32
Filed: 1983-04-08
Abstract: PURPOSE:To improve the heat transfer rate by a structure wherein heat transfer medium is prevented from being separated while flowing between fins and at the same time changed the flow direction of flowing heat transfer medium in order to destruct the boundary layer formed on a fin base and then to adhere the main flow to the fin again. CONSTITUTION:A fin consists in forming bridge shape bits 10, which are shaved upright from the fin after lancing a fin base 9 and have thin wing sections, with the wind chord of which is inclined at the angle of attack of alpha degrees with respect to the flow direction of heat transfer medium. When fins are laminated and heat transfer medium is flowed between the fins, the heat transfer medium flows between the fin bases and the bridge shape bits 13 as indicated with streamlines 11. When the angle of attach alpha degrees is adequate, the heat transfer medium flows along the thin wing bits 13 without separating therefrom so as to change its flow direction. On the other hand, the heat transfer medium flowing on the fin bases 12 starts to form boundary layers on the fin bases 12. However the heat transfer medium, the flow direction of which is changed, collides with said boundary layers so as to destruct the layers and adhere the main flows flowing from the wing bits 13 to the wall surface of the fin bases 12, resulting in remarkably improving the heat transfer rate at the main flow adhesion parts on the fin bases 12.

Title: Absolute type encoder
Inventor: CHIKAOKA TAKASHI
IPC: G01D5/245
Filed: 1989-03-15
Abstract: PURPOSE:To enable detection of an absolute angle beyond 360 deg. with high resolutions by storing an absolute angle within 360 deg. mechanically with an angle of rotation and a plurality of revolutions of a code plate as axial position thereof. CONSTITUTION:On a code plate 31, codes 32 made up of a number of transmission type slits storing absolute angles within 360 deg. are arranged being aligned circumferentially. A plurality revolutions of a rotating shaft 14 are stored mechanically as axial current position of the code plate 31. When a power source is closed, a fine angle detector 41 determines the absolute value within one rotation of the code plate 31 instantaneously and a coarse angle detector 51 determines an absolute angle of (n) rotation X 360 deg. from absolute zero deg. of the shaft 14 from the current position of the code plate 31. Then, an angle detection means 61 adds outputs of the detectors 41 and 51 to the results. This enables mechanical detection of the absolute angle beyond 360 deg. with high resolutions.

Title: Circuit and method for reset at power-on time
Inventor: MATSUMOTO NOBU
IPC: H03K17/22
Filed: 1984-03-30
Abstract: PURPOSE:To prevent breakdown of the operation by discharging the electric charge of a capacitor to only a circuit to be supplied, which is operated by a power source voltage, not to flow out this electric charge to external circuits when the power source voltage is varied. CONSTITUTION:When a power source is turned on at a time t0, power is supplied from an external power supply line 2a through a diode 11, and a potential V2 of an internal power supply line 2b rises quickly. At this time, since a capacitor 6 is charged through a resistance 12 because an n-FET13 is turned off, a potential V8 of a signal line 8 rises slowly from a time t1. When the potential V8 exceeds the threshold of an inverter consisting of n-FETs 15 and 17 at a time t3, a terminal 18 goes to the low level to terminate reset, and the circuit to be supplied is set to the operation state. If an accident or the like occurs in a power supply circuit connected to a terminal 1 at a time t4 to cause momentary reduction of the power source voltage and the potential difference between V2 and V8 reaches a threshold VTH of the n-FET13 at a time t5, the n-FET13 is turned on, and the electric charge of the capacitor 6 is discharged to the circuit to be supplied through the internal power supply line 2b. Therefore, reduction of the potential V2 is held down as shown by a solid line in the figure.

Filed: 1989-03-14
Abstract: PURPOSE:To prevent toner from being used wastefully in a non-image area by controlling a switch changing over so that a photosensitive base part is connected to a reference potential point or a developing bias power source. CONSTITUTION:Although a bias voltage is applied to the sleeve 11 of a developing unit 10, a control means 14 changes over the switch 8 so that the photosensitive base part 2 is connected to the developing bias power source 13. Consequently, an electric field which causes toner not to be attracted to an unelectrified photosensitive body 1 is created between the sleeve 11, thereby preventing toner from attaching to the non-image area. Therefore, the attachment of toner to an unnecessary part can be evaded even if a main electrifier is constantly operated, and accordingly toner is not wastefully used in the non-image area.

IPC: G03F1/00
Filed: 1985-03-27
Abstract: PURPOSE:To improve the precision of a mask external form and the size of the mask external form by shaping a plurality of X-ray absorptive patterns onto one surface, forming a reinforcing film onto the surface of an X-ray transmitting thin-film board with a substrate patterned for a support frame on the other surface and cutting and dividing the thin-film board into a plurality of masks for X-ray exposure. CONSTITUTION:An X-ray absorptive pattern 3 is formed on one surface, and a reinforcing film 5 is shaped on the surface on the X-ray absorptive pattern side of an X-ray transmitting thin-film board 2 with a substrate 4' patterned for a support frame 4 on the other surface. A material, which gives a thin-film sufficient strength and can be dissolved and removed in aftertreatment or does not damage the function of a mask 1 for X-ray exposure, is used as the quality of materials of the reinforcing film. The reinforcing film is shaped, and the thin-film board is cut and separated while using reference markers 8 for cutting as marks. Accordingly, the high accuracy of cut end surfaces is acquired, thus improving the relative positional accuracy of a mask external form and the X-ray absorptive pattern.

Title: Programming to semiconductor device
Inventor: WAKUTSU TOSHIYUKI
IPC: G11C17/00
Filed: 1994-03-31
Abstract: PURPOSE:To shorten a processing time for programming by programming a semiconductor device correctly without checking whether a correct data is written in the semiconductor device during a continuous writing time because a loop count is known beforehand. CONSTITUTION:A semiconductor device 2 is connected to a programming device 1 and, data are written in a user memory area 3 of the semiconductor device 2. A loop count memory area 4 is an area where a loop count N is written/read. A row decoder and an input circuit for inputting addresses from outside are additionally required so as to designate the area 4. Characteristics of a memory cell are dependent on an environment when the memory cell is manufactured. Memory cells in the semiconductor device have nearly the same characteristics, so that the memory cells are successfully written by programming of the same number of times. Since a repeating number of times is determined for every semiconductor device, a maker measures the loop count N when inspecting the semiconductor device and stores in the loop count memory area 4 inside the semiconductor device 2. Accordingly, a programming time is shortened in this constitution.

Title: Controller
Inventor: AZEGAMI TADASHI
IPC: G05B11/42
Filed: 1989-03-15
Abstract: PURPOSE:To attain the high response and to prevent the overshoot of the process variable by performing the switching between the PID arithmetic and the IPD arithmetic in accordance with the deviation between the set value and the process variable and the manipulated variable. CONSTITUTION:A switch 10 is turned on via a control part 13. The output set value SP' of a filter 1 rises linearly as the time elapsed, and the deviation which is operated by a deviation arithmetic part 11 between the set value SP' and the process variable PV is inputted to a proportional arithmetic part 12. The manipulated variable is operated by the PID arithmetic. Therefore the value PV follows the value SP' with a fixed deviation and the switch 10 is kept turned on. When the value SP' approximates to the set value SP and its change becomes slow, the deviation between the value SP' operated by a deviation arithmetic part 2 and the value PV is reduced. Thus the part 13 turns off the switch 10. As a result, the value SP' is not inputted to the part 11 any more and only the value PV is inputted to the part 12. That is, the manipulated variable is operated by the IPD arithmetic. This arithmetic switching operation contributes to the improvement of the follow-up performance and the prevention of the overshoot.
