Title: Traveling object identification device
Inventor: NABESHIMA HIDEO
IPC: G01S13/78
Filed: 1992-01-10
Abstract: PURPOSE:To provide a traveling object identification device for which deceleration down to a speed communicable between a responsor and an interrogator while a high-speed traveling object retaining the responsor passes through the communication area of the fixed interrogator is not necessitated in a system for identifying the high-speed traveling object. CONSTITUTION:This device is composed of the responsor 2 in an intermittent reception state retained by the high-speed traveling object 1 and the interrogator 4 for reading information without contacting from the responsor 2' in a continuous reception state retained by the high-speed traveling object 1' after a certain period of time and the interrogator 3 for starting for transmitting signals for starting the responsor 2 from the intermittent reception state to the continuous reception state so that the responsor proceeds to the continuous reception state in the communication area of the interrogator 4 is provided separately from the interrogator 4 for communication. Thus, the responsor 2' is in the continuous reception state when passing through the communication area of the interrogator 4 and the failure of the communication does not occur even when the high-speed traveling object passes through while maintaing the high speed.

Title: Solid-state image pickup element
Inventor: HAMAZAKI MASAHARU
IPC: H04N5/365
Filed: 1989-01-10
Abstract: PURPOSE:To reduce fixed pattern noise and low frequency noise of a current source by transmitting a signal to an analog storage capacity so as to cancel an offset signal in different directions depending on 1st and 2nd periods. CONSTITUTION:A capacitor CH is provided between an output section and vertical readout lines VRm, VRm+1, VRm+2... in a solid-state image pickup element having an amplifier function of picture elements arranged as a matrix. Then a signal from a picture element is transferred from one electrode for a 1st period being a horizontal blanking period and an offset signal is transferred from other electrode of the CH after the reset of the picture, horizontal scanning is applied and outputted after the blanking period. Thus, a signal eliminated with a fixed pattern noise or the like is outputted.

Title: Electronic timer
Inventor: SUEHIRO NORIYUKI
IPC: D06F33/02
Filed: 1983-01-12
Abstract: PURPOSE:To prevent a device using the timer from being stopped because of external noise by receiving a signal inputted after a time setting signal is received once so long as the signal does not continue for a prescribed time when the signal is a time signal. CONSTITUTION:When a scan signal is outputted from a scan signal output terminal (a) of a microcomputer 12, the scan signal enters one of scan signal input terminals (c), (d)... through a contact closed by the setting of a cleaning time setting encoder 8. Since the time is determined at input terminals (c), (d)... to which the scan signal is entered, the reading value becomes the setting time. Further, the reading value immediately after being read is not coincident with the value stored in the setting value memory and can show a value deviated upward and downward. Since the value is not recognized as an error so long as the value is deviated from the setting value for a prescribed time consecutively, however, the operation of the device using the timer is prevented from being stopped immediately because of external noise or the like.

Abstract: PURPOSE:To improve the accuracy of an output current by extracting a current flowing to a collector of the 2nd transistor (TR) as an output current. CONSTITUTION:The constant current circuit consists of the 1st npn TR Q1 and the 2nd npn TR Q2 in pairs to the collector of which a reference input current Io flows and the base and emitter of the TRs Q1, Q2 are connected in common respectively. An operational amplifier A is provided, whose non- inverting input (+) is connected to the collector of the 1st TR Q1, whose inverting input (-) is connected to the output terminal and whose output terminal is connected in common to the base of the 1st and 2nd TRs and the current flowing to the collector of the 2nd TR Q2 is extracted as the output current. Thus, the output current Iout flowing to the collector of the TR Q2 is equal to the input current Io fed to the collector of the 1st TR Q1 and the output current Iout without error is obtained.

Abstract: PURPOSE:To secure a large amount of capacity for the X-ray tube as well as to ensure the minute control for the X-ray focal position by providing the electronic radiation cathode in such a way that a number of X-ray focal points may be arrayed along the  shaft and on the outer circumference surface of the hand-drum shaped rotary anode provided within a vacuum container. CONSTITUTION:Anode stator 12 and 13 are sealed across cylindrical vacuum container 11, and rotor 16 and shaft 17 are supported to the stators via bearing 14 and 15. Rotary anode 18 of a cylindrical and hand-drum shape is fixed to shaft 17. Then a number of electronic radiation cathodes 21 are arrayed along the axial direction of the anode and opposing to anode 18. The X-ray focal point groups are formed by projecting each electron beam e generated from cathodes 21 onto the target and then arranged linearly when viewed from the X direction of the X-ray irradiation. Each cathode is independent to control the radiation of the electron. Thus, the X-ray tube can feature a large amount of capacity, and furthermore the minute control is possible for the X-ray focal position.

Title: Photoreceptor for copying and printing
Inventor: IDE YOUJI
IPC: G03G15/05
Filed: 1981-01-14
Abstract: PURPOSE:To obtain a large number of sheets of copy by exposing images to a photoreceptor previded with a layer contg. an org. photochromic compound on a photoconductive layer to form coloring image parts then repeating electrostatic charging of the entire part-full surface exposure-developing-transferring. CONSTITUTION:A photoconductive layer 2 and a layer 3 wherein an org. photochromic compound is dispersed in an insulation characteristic material are laminated on a conductive substrate 1, whereby a photoreceptor is formed. Images are exposed on this photoreceptor, whereby the org. photochromic compound is colored or decolored selectively, and colored images are formed on the layer 3. Thereafter, the entire surface is electrostatically charged and if the entire surface is exposed after this, the electric charge of the surface in the decolored parts leaks to form the electrostatic latent images corresponding to the colored images and therefore these images are transferred onto transfer paper after development. Since the colored images do not decolor on account of the presence of a difference in sensitivity, plural sheets of copy are obtained by repeating the full surface electrostatic charging and the subsequent stages.

Abstract: PURPOSE:To enable resin pieces to be crystallized without making them fused each other by soaking polyester resin into the warm water agitated up to the specific linear velocity and raising the temperature up to the proper temperature through a proper velocity. CONSTITUTION:The polyester resin is thrown and soaked into the warm water which is under the state of being agitated up to the linear velocity, at least, above 0.01 times of the sedimentation rate of the polyester resin in warm water, following this, the temperature raising is started while giving linear velocity continuously from the temperature lower 10 deg.C than the glass transferring temperature (Tg) of the drying period of the polyester resin, furthermore, the temperature raising is performed at the velocity not exceeding 100 deg.C per an hour up to the temperature higher at 15 deg.C than the (Tg) for the crystallization. After the resin treated through this manner is taken out of the hot water, lit is sufficiently removed with the moisture by the use of, for instance, a centrifugal dehydrator, and then transferred to the drying process.
