Title: Noise suppression circuit
Inventor: MINAMI TOKUO
IPC: H04B1/10
Filed: 1978-03-17
Abstract: PURPOSE:To enable to improve the noise suppression effect at a weak electric field strength, by inserting the circuit connecting in parallel with the diode and resistor between the emitter of two transistors consisting a differential amplifier and the constant current source. CONSTITUTION:The gain of the differential amplifier at weak input is suppressed by utilizing the characteristics that the forward resistor of diode is greater when the voltage across the diode is smaller and it is smaller when the voltage is greater. In the noise suppression circuit, the circuit 13 consisting of diodes 4 and 6 and the resistors 5 and 7 is inserted between the emitter of the transistors Tr3,9 constituting the differential amplifier and the constant current source 8. The output waveform of the circuit is as shown in solid lines of (a). The curve is for the case when the conduction angle is remarkably great and it is similar to the waveform as if the crossover of the class B push pull amplifier were present, but the waveform distortion of FMIF carrier signal gives on effect on the performance of the receiver. Further, the input-output characteristics is as shown in the solid lines of (b), and when the input is smaller, the noise can be reduced by the decrement of gain.

IPC: G21C7/20
Filed: 1989-02-10
Abstract: PURPOSE: To enhance the brake efficiency by providing a reset spring for moving a piston along a cylinder toward a top position where each discharge hole is opened by the piston. CONSTITUTION: When a control rod and the shaft 10 thereof are located at top position, a reset spring 38 holds a piston 30 at an extended position determined by abutment of a flange 40 on the lower end part of a cylinder 12, for example. When the shaft 10 and control rod are dropped, a hummer, i.e., a protruding part 42, hits the piston 30 which is thereby driven into the cylinder 12. Descending motion of the piston 30 is subjected to progressive brake action by the throttling action of fluid being discharged from a chamber 34 through holes 32 being closed sequentially.

Title: Cutting method of plastic liquid-crystal display element
Inventor: YOSHIDA SHINYA
IPC: G02F1/13
Filed: 1983-02-28
Abstract: PURPOSE:To cut a plastic liquid-crystal display element with a burr-free beautiful surface by employing half-cutting and reverse half-cutting by blades in combination. CONSTITUTION:Several slits matching with the cutting width of a product are worked in numbers of upper substrates 1. Further, half-cutting 4 is performed. Square holes 6 are punched numbers of substrates 5 at terminal parts of the product and half-cutting 4 is carried out similarly to the substrates 1. The substrates 1 and 5 form an assembly substrate 7 with a printed seal adhesive. The substrate is divided to the size of the product by upper and lower blades 8 and 9 which face each other from outside of the parts of half-cutting 4 of the substrates 1 and 5. Cutting-edges of the blades 8 and 9 only reach the areas of half-cutting 4, so the substrate is divided only by being cut slightly from the surface. Therefore, it is not necessary to apply extremely external force to the blades 8 and 9 and neither a decrease in the strength of the seal agent nor peeling is caused.

Title: Production and execution method for non-link type program
Inventor: TASHIRO MASAKAZU
IPC: G06F9/45
Filed: 1990-02-09
Abstract: PURPOSE:To perform the correction of a program regardless of an active or inactive mode by adopting constitution where the program calls sequentially the partial processing procedures converted into the practicable forms and transfers the control to these procedures for the execution of the total processing. CONSTITUTION:The data description inputted with a simple instruction code of a manager controls the procedures, the assembly data, and a history respec tively. An assembler assembles the procedures via the manager and the assem bled procedures are filed into a data description control file. In an execution program, a controller stores the data description part and procedure part which are required by a main program via the manager into the memory of the execu tion program. Then a program is executed by transferring the control to the stored address. Consequently, the controller and the manager are worked asynchronously with each other, therefore even a program in execution can be directly corrected.
