IPC: H04N5/225
Filed: 1984-09-20
Abstract: PURPOSE:To search securely the counter of an electronic still camera with simple constitution by constituting such that the camera is initialized after a prescribed time is lapsed since the loading of a magnetic disk is detected by a detection means. CONSTITUTION:When a magnetic disk pack is loaded on a camera main body and a pack detection switch SW1 and counter switch SW2 is turned on and off, respectively, the cleared state of fourbit counter U1 is released, and the counter U1 starts counting. After the counter counts 16 times (267ms), a carrier is outputted, and an output Q of an RSFFU2 is set to '1'. As a result, an AND gate G2 is opened, and the bit output of the counter U1 passes through the gate G2 to drive a counter search drive source. Its drive pulse repeats '1' and '0' every 4V (V=16.7ms). For this time, six-bit counter U3 counts the output pulse of the gate G2, and shifts a head by one track whenever the counted value comes to '1'.

Title: Counter circuit
Inventor: TANIGAWA TOSHIYUKI
IPC: H03K21/40
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the occurrence of a hazard in a carry signal by latching a signal generated in synchronizing with a sub clock pulse at this side of the carry signal at a preceding stage of a flip-flop by a main clock pulse and setting it as the carry signal at the next stage. CONSTITUTION:The same operation as the one in a conventional circuit is performed in times between 1t-11t in figure (a), and in times between 12t-15t, both logics on signals 13 and 18 become '1' and '1' on a signal line 21. The signal is inputted to a D-type flip-flop (FF) 41 and is latched synchronizing with a positive clock signal and is taken out as the signal of a signal line 22. Therefore, the signal becomes '1' in times between 14t-17t and can be used as the carry signal at the third stage. Even when the signal on the signal line 14 is delayed against the signal on the signal line 18 (figure b), the signal which has latched the signal on the signal line 21 on the FF14 by the positive clock is synchronized with the positive clock pulse, thus preventing the occurrence of the delay and the hazard.

Title: Data transfer control system
Inventor: TERADA MASATOSHI
Filed: 1987-08-10
Abstract: PURPOSE:To improve the throughout of data and to reduce the number of packets by superimposing an instruction of transmission enable onto a data when a logical communication path passes through a packet exchange network and using a transmission enable packet when the path passes through a private line network. CONSTITUTION:When the logical communication path used by the user passes through a packet exchange network 203, the flow control system superimposing the instruction of transmission enable to the sender side onto the data is used so as to suppress the transmission of a transmission enable packet. Thus, the number of sent transmission enable packets is less and the charging to the packet is reduced. On the other hand, when the private line network 204 is passed through, the instruction of transmission enable is not superimposed on the data and the flow control system having higher transfer priority then the data and using the transmission enable packet not limited by the limit of the flow control is used. Thus, since the transmission enable packet is informed to the opposed user without being affected by the data transfer priority, the data throughput is improved.

Title: Temperature control circuit for object to be heated
Inventor: HAJIMA KAZUYUKI
IPC: G05D23/19
Filed: 1989-07-31
Abstract: PURPOSE:To detect the abnormality without using any independent protection circuit for detection of abnormality by providing plural temperature control systems with different control target levels set and switching these control systems with each other for execution of the temperature control. CONSTITUTION:A normal range of fluctuation is decided as long as the comparison values H1 and H2 are kept in a range of R+ or -alpha, where R shows the ideal count value and alpha shows a normal range of fluctuation caused by the influence of an external environment, etc. Then a trouble of a temperature control system is decided when the value H1 exceeds the range of R+ or -alpha since the automatic correction is impossible. Thus an abnormal signal is sent to a switch selection means 6, and the corresponding one of both control systems 4 and 5 is forcibly stopped via a switch means 8a or 8b. Then a fixing action is controlled without performing a switch action with one of both systems 4 and 5 only before the faulty system is repaired. As a result, the abnormality can be detected without using any independent protection circuit for detection of abnormality.

Abstract: PURPOSE:To execute easily and exactly a measurement by deriving a beam spot diameter from a square wave current for oscillating a beam spot. CONSTITUTION:A beam spot diameter measuring device 2 is placed on the center area on the outside face of a face panel 7 of a sample image receiving tube 1. The measuring device 2 is provided with a U-shaped magnetic material piece 3, a coil 4 wind-installed to its two leg parts 3a, 3b, a variable square wave current generating source 5 connected to the coil 4, and a magnifying lens 6.

As a result, two beam spots 14 are generated in two places like time division. Subsequently, magnitude of a square wave current in case when both beam spots are armoured is measured by adjusting an output current of the current generating source 5. Basing on this measured value, a beam spot diameter is obtained.

Title: Optoelectronics picture sensor
Inventor: KAARUHAINTSU ROOZAN
IPC: H01L21/768
Filed: 1988-08-09
Abstract: PURPOSE: To improve the photosensitivity and prevent crosstalks by expanding or reducing the width of conductors to make always const. the sum of coupling capacitances of all sections of the adjacent conductor lines, irrespective of the total length. CONSTITUTION: Sections of conductor lines are numbered from L1 to L8, starting from a bottom electrode of a photodiode. The length of the section L4 increases by a center interval R5 (conductor line raster) of the section L5 every increment of the conductor line number, L5 increases by R4, L6 decreases by R5+R7 and L7 decreases by R6. Thus, the total length always changes by the same amount. The capacitance between conductors 1, 2 mainly results from the line section L6 while that between a pair of conductors 62, 64 mainly results from L4. Thus the reduction of C6 (capacitance across L6) can be compensated with the increase of C4 (capacitance across L4).

Title: Lithium battery
Inventor: TOMITA MASAO
IPC: H01M2/18
Filed: 1993-07-16
Abstract: PURPOSE:To provide a lithium battery capable of improving performance and safety. CONSTITUTION:A positive plate 1, surrounded by a separator 3 formed of a fine porous film, is surrounded by a separator 4 formed of nonwoven fabric, and a battery is formed by alternately laminating the positive plate 1 surrounded by two layers of these separators and a negative plate 2 mainly composed of lithium. Accordingly, since the positive plate of high internal resistance is surrounded by the separator formed of the fine hole film, a temperature of the positive plate is quickly increased when generated an internal short-circuit, to enable a battery temperature rise to decrease by closing a fine hole of the fine hole film by this positive plate temperature, and further since the separator formed of the nonwoven fabric holds an electrolyte, a time of discharge can be lengthened.

Filed: 1983-10-26
Abstract: PURPOSE:To correct deformation caused in fixation, and discharge paper stably and also prevent a defect in transfer, etc., even in the both-surface copying operation by curving a sheet after transfer in the opposite direction of natural curvature in the fixation. CONSTITUTION:The paper 20 after transfer is fixed between fixing rollers 15, separated from an upper roller 16 with a separation pawl 24, and inserted between paper discharge rollers 18. The peripheral speed of the rollers 18 is faster than that of the fixing roller 15, so the sheet 20 is tensed and pressed against the circumference of the peak 22a of a guide plate 20. Consequently, the sheet 20 is brought into strong sliding contact with a plate 22 which is curved in the opposite direction of natural curvature along the roller 16 during the fixation to correct the natural curvature, so that the sheet is discharged into a paper discharge tray 21. Therefore, the sheet 20 is neither folded during paper discharge nor fallen out of the paper discharge tray 21, and discharged stably.
