Filed: 1985-07-24
Abstract: PURPOSE:To perform early and easily an integrated action analysis of an electronic computer by stopping the signal tracing action through any CPU with an internal or external trace stopping signal. CONSTITUTION:It is supposed that the necessary parts of both CPU 1 and 2 are reset and the CPU 1 delivers an indication for selection of the external trace stopping signal in any operating method after a prescribed signal tracking action is started. Thus a tracing stop condition selector 201 of the CPU 2 selects the internal trace stopping signal 211. While a tracing stop condition selector 101 of the CPU 1 selects the external trace stopping signal 213. Thus a tracking stop flag 202 is set at 1 in the CPU 2 by the signal 211. Thus the tracking operation is through. At the same time, a tracing stop flag 102 is set at 1 in the CPU 1 by the signal 213. Then the tracking operation is through.

Title: Manufacture of waveguide type polarizer element
Inventor: AKITA OSAMU
IPC: G02B6/12
Filed: 1988-06-29
Abstract: PURPOSE:To manufacture waveguide type polarizer element at low cost by manufacturing a polarizer by a proton exchanging method so that the periphery of a part where the polarizer is formed on a waveguide previously on a substrate is covered completely. CONSTITUTION:A mask 6 for polarizer manufacture is vapor-deposited on the substrate 1 where the waveguide 2 is formed and then a polarizer pattern is formed thereupon of photoresist. At this time, a polarizer pattern is made wider than the waveguide 2 to facilitate the aligning of the waveguide 2 and polarizer pattern. Then the polarizer pattern made of the photoresist is used as a mask to pierce an opening part 7 for proton exchange in the Ti film 6 of the polarizer manufacturing mask by using fluoric acid. Then the proton exchange of the substrate 1 is carried out to obtain the waveguide polarizer element which has the polarizer 3 formed covering the center part of the waveguide 2 on the substrate 1. Consequently, the requested aligning of the waveguide and polarizer becomes low in accuracy, so the production efficiency is high and the cost is reducible.

Title: Helix-type traveling-wave tube
Inventor: HASHIMOTO HIROYUKI
IPC: H01J23/50
Filed: 1981-10-12
Abstract: PURPOSE:To increase the heat capacity of the joint part of a helix-type traveling-wave tube, and enable the heat radiation to be efficiently carried out by filling a high-melting-point metal into the joint part between a helix and a coaxial output-connecting part. CONSTITUTION:The distance between a helix 2 and an inner conductor 5 is made as small as, for example, around 0.5mm.. After that, a high-melting-point metal is poured into the space formed between the helix 2 and the conductor 5 by use of a laser welder or the like so as to form a joint part 1. As a result, heat generation at the joint part 1 is suppressed, and heat can be efficiently transmitted to the helix 2 and the conductor 5. Therefore, the safety of the operation of the tubular bulb can be enhanced even when the frequency and the output of a helix-type traveling-wave tube is increased.

Filed: 1980-11-17
Abstract: PURPOSE:To reduce the power consumption of a battery, by supplying the voltage of the battery only to a volatile memory such as a dynamic memory, etc. in case the power supply is interrupted. CONSTITUTION:When a switch 1 is applied, the AC power supply 100V is applied to power supply circuits 2 and 3 to produce the DC voltage. Service interruption circuit 5 receives no supply of voltage from a battery 4, and a service interruption circuit 6 receives the supply of voltage from the battery 4 respectively when the power supply is interrupted. For the circuits 5 and 6, contacts 11a-11j of a relay 11 are closed by the relay signal supplied from a CPU8. Thus the circuits 5 and 6 are electrically connected to each other. When the AC power supply is interrupted and the DC voltage of the circuits 2 and 3 lower down to a prescribed level of voltage, a power supply interruption detecting circuit 7 feeds the relay drive signal to the relay 11 to turn off the relay 11 and to separate the circuit 5 from the circuit 6. At the same time, an address switch circuit 17 witches the refresh address signal given from a refresh address counter 21 to a dynamic memory 20.

Title: Rotation control device for information recording medium disk
Inventor: HACHI YASUO
IPC: G11B19/24
Filed: 1978-12-25
Abstract: PURPOSE:To avoid deterioration of the stability for the control loop for fixed linear speed rotation  by securing the fixed control for the gain of the rotation control servo loop of the disk which performs the fixed linear speed reproduction and regardless of the radius position of the reproduction element. CONSTITUTION:The monomulti MM of frequency discriminator circuit FD is triggered by the  driving motor rotation detection pulse of the disk or the like, and then the frequency discrimination signal voltage is applied to amplifier MDA in correspondence to the different numbers of  rotation according to the radius position of the disk or the like of the reproduction element. Thus  the servo control is given to the rotation number of the motor to secure the fixed linear speed  reproduction according to the position of the reproduction element. At the same time, the frequency discrimination signal is applied to limiter signal generator circuit LVS of circuit FD to give  the control to the limit voltage of gain control part GS which forms the motor rotation control  servo loop along with phase comparator PC which gives a control between the reproduction synchronous signal and the reference signal in accordance with the position of the reproduction  element, servo amplifier SA and others. As a result, the gain of control part GC becomes constant  regardless of the radius position of the reproduction element, thus preventing the deterioration of  stability for the fixed linear speed rotation control loop.
