Title: Signal interpolating method of decoding circuit of dpcm-coded signal processing circuit
Inventor: KAMIYA KENJI
IPC: H04B14/06
Filed: 1982-11-02
Abstract: PURPOSE:To perform excellent DPCM encoding with the minimum usage of memory by chopping a component of a differential analog signal in every decoding period at plural points by a chop control signal, and performing integration plural times in every decoding period. CONSTITUTION:A differential digital signal outputted from a digital processing circuit 4 is converted by a D/A converting element 7 into a differential analog signal, which is sent to a gate 10 consisting of an analog switch. An interpolating pulse generating circuit 9, on the other hand, generates an interpolating pulse signal on the basis of a clock signal from a master clock circuit 5 so that two pulse signals are positioned at a stable intermediate part in a signal in one stepwise decoding period of the differential analog signal, thereby outputting it to the gate 10 as the chop control signal. When the chop control signal with a high level is applied to the gate 10, the gate 10 extracts the intermediate part of the differential analog signal in each period as a difference signal with a quantization level intermittently twice each and sends it to an integrator 8.

Title: High output optical fiber amplifier
Inventor: OISHI YASUTAKE
IPC: H01S3/0941
Filed: 1994-08-17
Abstract: PURPOSE:To obtain an amplifier whose efficiency is higher than the conventional one when used as a booster amplifier, by setting the intensity of an incident pumping light from the optical fiber end from which a signal light is outputted higher than an incident pumping light from the optical fiber end from which a signal light enters. CONSTITUTION:A Pr<3+> added Z-F4, based fluoride optical fiber (core diameter:1.6mum, core/clad specific refraction difference: 3.7%, Pr<3+> concentration:500ppm, length:20m) 1 is excited by pumping light sources 2a, 2b, through optical couplers 3a, 3b. A light signal whose wavelength is about 1.30mum is inputted from a signal source 4, and a signal light is outputted. In this case, the backward excitation intensity (excitation intensity by the pumping light source 2b) is made greater than the forward excitation intensity. The optical fiber l for amplification is divided into two fibers and bilaterally pumped to output a signal.

Filed: 1987-07-31
Abstract: PURPOSE:To prevent a torque shock from occurring in a way of compensating a sudden change in engine output by controlling ignition timing at the time of on-off transfer of an on-off valve which controls an interconnecting state between each independent exhaust passage to be connected to a turbosupercharger. CONSTITUTION:A 4-cylindered engine E is provided with an exhaust turbosupercharger 14 for supercharging suction air, and it installs an exhaust interconnecting passage 28 interconnecting each independent exhaust passage 8 of respective cylinders to be connected to the exhaust turbosupercharger 14, while it sets up an on-off valve 29, controlling an interconnecting state between each independent exhaust passage 8, in this exhaust interconnecting passage 28. And, when a driving state of the engine E comes under a high speed, high load area, the on-off valve 29 is opened, and when it comes under a low speed, low load area, this on-off valve 29 is closed the other way. Here, when the driving state of the engine E is varied and the on-off valve 29 is selected, ignition timing is regulated by a control circuit 25. With this constitution, a sudden change in engine output is compensated so that occurrence of a torque shock is effectively controlled, thus a travel feeling is improved.

Abstract: PURPOSE:To make it possible to detect latch-up which occurs in burn-in visually and easily by carrying out burn-in in the condition that heat sensitive material is put on the top face of an IC device. CONSTITUTION:A device 1 is set in a socket 3, a sheet of heat sensitive paper 4 is put on the top face of the device 1, and the heat sensitive paper 4 is pressed by a reatiner plate 5 so that it is not off from the right place. Burn-in is carried out in-such a condition. As for the device 1 in which latch-up does not occur, the heat sensitive paper 4 in the part is not discolored because temperature does not rise much. As for the device 1 in which latch-up occurs, the heat sensitive paper 4 in the part is discolored because temperature rises. Consequently, it is possible to know that latch-up has occurred in the device 1 in the part by discoloring of the heat sensitive paper 4. Such heat sensitive paper 4 that is discolored at a temperature higher by 15 to 30 deg.C than the temperature in a burn-in device, 120 to l30 deg.C, is used.
