Inventor: OKADA AKIRA
IPC: F16H63/36
Filed: 1982-10-16
Abstract: PURPOSE:To eliminate the need for boring a number of through grooves on a wall part and consequently enable to thin the thickness of the wall part by a structure wherein a double intermeshing protective pin is fitted between two shifter shafts on the outer side face of the wall part and prevented from coming off by a keep plate.

Abstract: PROBLEM TO BE SOLVED: To prevent a solid matter from becoming scorched powder, by providing a spraying-drying chamber and a fluidizing-drying chamber in a directly joined state and by constructing a hot air sending-in port out of a combination of a honeycomb structure and a low-air-velocity porous plate, in the equipment wherein a liquid to be dried is sprayed in an atomized state into a hot air flow and dried therein instantaneously. SOLUTION: On the occasion of drying a material liquid, it is sprayed downward at a high flow velocity into a spraying-drying chamber 1 from a pressure spray nozzle 9 and, at the same time, hot air for drying is sprayed from an annular hot air sending-in port 11 constructed of a combination of a honeycomb type heat dispersing plate 20 and a porous plate 21 and provided around the nozzle 9. By this constitution, the hot air flows downward to a fluidizing-drying chamber 17 in a manner of enveloping liquid droplets and water in the liquid droplets is vaporized in the course.  The large ones of the sprayed liquid droplets are not dried completely, but contain the water yet, and therefore the exhaust from the chamber 17 is introduced into an adjacent cyclone through an exhaust chamber 8 and a discharge port 13 from the lower part of a vertical partition wall 6 and the water is separated therein from the exhaust.

Title: Pressure measuring method
Inventor: OONISHI TAKASHI
IPC: G01L23/00
Filed: 1981-11-13
Abstract: PURPOSE:To calculate the true internal pressure by measuring the pressure in a pressure vessel of which the pressure fluctuates periodically by means of two pipes having different lengths and comparing the phase difference of pressure waveforms and the difference in frequency components. CONSTITUTION:The columnar oscillations generated in pipes 2, 3 differe in frequency and magnitude thereof because the pipes 2, 3 vary in length. Therefore, if the frequency components having differences in amplitude are removed, the pressure components of only the internal pressure of a pressure vessel 1 can be extracted. More specifically, the pressure signals detected with pressure gages 4, 5 are inputted as digital signals via an amplifier 7, a scanner 8 and an A/D converter 9 to a central control unit 10. In the unit 10, the data of the two crown angles theta-pressure P is once stored in a disc 11, and is operated, whereby the curve of the pressure and the crown angle is obtained. This curve provides the pressure waveforms of only the internal pressure of the vessel 1 wherein the oscillations in the pipes are cut off. The phase of the curve is deviated and the true internal pressure of the vessel 1 is calculated.

Filed: 1989-07-13
Abstract: PURPOSE:To avoid the inability of data transmission/reception by allocating line buffers used in respective communication lines within the range of a maximum number for allocating the line buffers, which is previously given at the time of initializing a system. CONSTITUTION:The line buffers 81 are acquired from a line buffer pool 8 which is temporarily used as a transmission data information storage area so as to attain allocation at the time of transmitting and receiving data with terminal equipments 1 and 2 or the other host computer within the range of the maximum number for allocating the line buffers, which is previously given to respective communication lines 4 and 5 when the system is initialized for a line buffer acquirement request from a communication control means 6. Consequently, all the line buffers 81 come to be used by transmitting and receiving data between the terminal equipments 1 and 2 and an online program means 7. Thus, the biased use of the line buffers 81 in a specific communication line can be avoided, and the use of the line buffers 81 in the other communication line can be ensured, whereby the inability of data transmission/reception owing to the lack of the buffers can be avoided.

Title: Protecting circuit of static induction type transistor device
Inventor: CHIBA CHOJI
IPC: H01L29/78
Filed: 1988-07-20
Abstract: PURPOSE:To detect a failure rapidly and surely to protect SITs and their environmental components by a method wherein the value of a negative bias voltage between a gate and a source of a SIT drive circuit is compared with a certain set voltage value. CONSTITUTION:A switching voltage of an input signal is inputted into a drive circuit 17, and when the signal is inputted between a gate and a source of SITs 11-14, a negative bias voltage becomes small, as a drive current is made to flow to make a voltage drop occur in a drive circuit power source. When the SIT becomes defective and shortcircuited from the standpoint of a gate, a gate input resistance decreases, so that a drive current flows furthermore and a voltage drop grows large. And, when the SIT is defective and open-circuit from the standpoint of a gate, a gate current does not flow. Even if SITs are connected in parallel with each other and one of them becomes defective, the voltage becomes larger than the voltage in normal operation. The value of a negative bias voltage applied to a gate side drive circuit 17 is compared and judged through a comparative circuit 3 to detect the failure of the SIT.
