Filed: 1981-05-15
Abstract: PURPOSE:To engrave a colored blow mark of the same shape as a cut out hole by sand blasting the outer face of a cylinder masked leaving a cut out hole of desired shape with colored sand. CONSTITUTION:A cylinder (a) is transferred to a marking position A with the front of circular arc of the cylinder body on which marking is to be made kept in front.

Title: Electrophotographic device
Inventor: TAKEI TETSUYA
IPC: G03G15/00
Filed: 1982-05-04
Abstract: PURPOSE:To eliminate unevenness on a picture due to a blade mark, etc. when restarting an operation of a copying mark, and to stabilize and equalize the picture, by moving a photoreceptor at a low speed even when the operation is stopped. CONSTITUTION:After an operation of an electrophotographic device is stopped for many hours, a difference of the residual potential is generated on a photoreceptor due to a difference of an air flow in a device case, leakage light from the outside, and especially, a stop contact with a blade of a cleaner, a developing device, etc., by which density of a picture becomes unequal in the beginning of the re-operation. Therefore, this device is provided with a means for rotating a photosensitive drum 6 at a low speed by an optional electric and mechanical means, in the stop period of the picture forming operation. In this way, it is possible to eliminate the unevenness of a picture due to a difference of a residual potential distribution and a difference of a temperature distribution on the photoreceptor, and to obtain a stable and uniform picture.

Title: Method and apparatus for driving output pad
Inventor: DARIRU II ANDAASON
IPC: H03K17/687
Filed: 1991-03-14
Abstract: PURPOSE: To optimize the drive circuit of an output pad of a logic integrated circuit with respect to a noise level by applying an IC output signal to 1st and 2nd pad drivers. CONSTITUTION: When a noise level on a ground line is too high, a logical '1' state is fed to a lead wire 67 to allow a flip-flop 64 to receive the logical '1' state at a terminal Q by a clock signal and to provide the logical '1' state to a conductor wire 66. Thus, '1' level appears on a conductor wire 40 and a '0' level appears at an output of an inverter 28. When a '0' level is given to a NAND gate 32, a level of a conductor wire 36 is always at a '1' level and a FET 48 is always nonconductive. Similarly when a '1' level is applied to the conductor wire 40, an output level of a NOR gate 38 on a conductor wire 42 is always '0', and an FET 58 is also nonconductive. Since a connection part of the FETs 48, 50 is cut off from a power supply and ground, its level follows a signal generated by FETs 44, 46.  The FETs 44, 46 are continuously driven, and a conductor wire 22 and an output pad 20 are driven in response to an IC output signal on the conductor wire 24.

Title: Compensating circuit, compensating method and radar equipment
Inventor: YAMAMOTO KAZUHIKO
IPC: G01S13/89
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To carry out a range tracking or a Doppler tracking by reducing a tracking error, even when the range of a target or a Doppler frequency of reflection waves are changed in accordance with movements of the target. SOLUTION: This radar equipment repeats, at a plurality of frequencies (hits), a process of emitting frequency pulses to a target and pulse-compressing received echoes, and obtaining a high resoluble data column (range profile) in a distance direction. A distance tracking of the range profile obtained as the result is performed, and by using the results, a range compensation is made that reception signals from the same reflection point are arranged in the same range. Range tracking means 501 deems a history of the range profile as a two-dimensional image having two shafts of hit-range, and inputs it to a shift amount estimating circuit 116. The shift amount estimating circuit 116 estimates inclinations of a plurality of segments having the same inclinations existing in the input images and outputs the results.  The range tracking means 5-1 outputs an inclination output from the shift amount estimating circuit 116 as a temporal change of a distance to a target.

Abstract: PURPOSE:To keep the inside of a device main body in the clean state by providing a stain detecting means which optically detects the degree of stain in the device main body in accordance with the degree of scattering light due to dust in air in the device main body. CONSTITUTION:A part of the air current in a device main body 13 passes a pipe 21 and receives the emitted light from a light emitting part 22, and scattering light due to dust in air is received by a light receiving part 23. It is judged whether the output of the light receiving part 23 is larger than a threshold level or not by a first comparator 25. When the output exceeds the threshold level, an analog switch 26 is operated, and a current exceeding the threshold flows to an integrating circuit 27; and when the energy stored in the circuit 27 exceeds a reference value, a signal is outputted from a second comparator 28 to a control means 29 to operate a warning means or stop the operation of the device. Thus, the inside of the device main body is kept clean to prevent an optical means from being dirtied, and therefore, information is accurately recorded on and reproduced from an optical disk.

Title: Scissors
Inventor: HIRAKAWA HACHIRO
IPC: B26B13/28
Filed: 1989-03-27
Abstract: PURPOSE:To release an artisan from an abuse of its fingertips, who often sues scissors for long hours by forming a chamfering part by removing the end part on the edge line side of a holding edge, at a contact part around a pivotal spindle at which it is provided on the inside surface of each of finger-rest sides for a moving edge and the holding edge. CONSTITUTION:In a closing stroke of scissors, both of connection planes on a contact part are slid almost parallel with each other, and cutting is entirely done by both a curve of the scissors and a twist by an artisan like usual scissors, at the initial stage at which a contact part 5 between a moving edge 1 and a holding edge 3 is overlapped each other. In an intermediate position at which the cutting quality of the scissors is going to become dull, their connection is made strong at the front end of the progressing direction of overlapping on the contact part 5 when a twist operation is applied to fingertips. At this time, since both a chamfering part 6 of the end part on the contact part 5 on the side of the holding edge 3 and the end part without a chamfering part on the side of the moving edge 1, are approached with each other, a parallel slide between the connection planes on the contact part is altered to a wedge type slide. Since a wedge effect is thus applied to the cutting point of the scissors, it is possible to cut without sharpness being lost.

Abstract: PURPOSE:To prevent unvaporized mercury at the time of lighting by specifying the lamp input, mercury vapor pressure, and the ratio between the volume of an anode and the inner volume of a light emitting space expansion section at the time of lighting. CONSTITUTION:The lamp input is set to 1kW or above, the mercury vapor pressure is set to 15 atm or below, and the ratio U/V between the volume U(cc) of an anode 2 and the inner volume V(cc) of a light emitting space expansion section 11 is set to 0.1-0.3 at the time of lighting. The lamp input is 1kW or above and the mercury vapor pressure is 15 atm or below at the time of lighting, thus the radiation light with a narrow half-value width of the line (g) or line (i) is obtained. The anode 2 located on the upper side is apt to be damaged when the discharge current is increased, however the ratio U/V between the volume U of the anode 2 and the inner volume V of the light emitting space expansion section 11 is set to 0.1-0.3, thus the damage inflicted on the anode 2 is considerably reduced, a long usage life is secured, and mercury is quickly vaporized. The stability of the radiation strength of the line (g) or line (i) is increased.
