Patent JP-H03143108-A (JP)
Title: Distribution amplifier
Inventor: KIKUCHI HIROYUKI
IPC: H03F3/60
Filed: 1989-10-30
Abstract: PURPOSE:To increase a gain variable width and to improve the reliability of an FET device by giving the drain voltage and the gate voltage of a distribution amplifier to the distribution amplifier via a series resistor, thereby decreasing the fluctuation of a drain-source voltage with respect to a gate voltage change without increase in the power supply voltage. CONSTITUTION:The drain voltage VD is expressed in equations I, II according to the Kirchhoff's law. Thus, an inter drain-source voltage VDS is expressed in equation III, where '50' in the equation III is the resistance of a termination resistor. When a voltage VGA is boosted, the gate voltage is increased, a drain current ID is increased, while the voltage VGA is decreased, then the drain current ID is decreased. Thus, it is possible to select resistors R1, R2 so that the term of the equation III, F=R1VGA-{R1R2+50(R1+R2)}ID is almost kept constant with respect to a change in the voltage VGA. Since the drain voltage is changed with respect to the change in the voltage VGA in such a manner, the fluctuation of the drain-source voltage VDS is decreased.

Title: Negative pressure regulator
Inventor: NAGAOKA HIDEO
IPC: F02M25/06
Filed: 1987-11-09
Abstract: PURPOSE:To enable negative pressure to be freely regulated with a simple economical constitution without using a diaphragm by advancing and with-drawing a movable iron core according to the excitation and non-excitation of a coil and affording and interrupting communication between a negative pressure inlet, a negative pressure outlet and an atmospheric inlet. CONSTITUTION:When a coil 6 is not excited and duty cycle is 0%, a movable iron core 14 is adhered to a seat portion 28 of an atmospheric inlet 26 by a spring 16. Thus, a negative pressure chamber 29 is shut off from the atmospheric inlet 26 so that pressure in the negative pressure chamber 29 and negative pressure outlet 24 is maintained in the same high negative pressure as negative pressure applied to a negative pressure inlet 22. On the other hand, when the coil 6 is not excited and duty cycle is 100%, the movable iron core 14 is attracted to a fixed iron core 1 against the spring 16 to be separated from the seat portion 28 of said inlet 26. Thus, said inlet 26 communicates to the negative pressure chamber 29, and pressure in the negative pressure chamber 29 and negative pressure outlet 24 is lower than that applied to the negative pressure inlet 22.

Title: Thermal insulation pulse-tube-type refrigerator
Inventor: HAYASHI YUZO
IPC: F25B9/00
Filed: 1992-10-21
Abstract: PURPOSE:To obtain a highly efficient and compact pulse-tube-type refrigerator having a refrigerating efficiency raised by an increase of a heating surface area and also having a pressure loss reduced, by using a cold head having a conical part provided in a low-temperature part. CONSTITUTION:It is assumed that a cold head 32 has no conical part 31, but has simply a flat-plate part. Then a heating surface area is insufficient naturally and, in addition, the performance deteriorates due to a large friction loss generated by a shock wave occurring on the flat-plate surface of the cold head 32, since a fluid strikes on the flat-plate surface and then flows in dispersion to a cold storage material 36 when it returns from a heated end part of a pulse tube 35 to the cold storage material 36. When the fluid enters the pulse tube 35 from the cold storage material 36 through the flat-plate part of the cold head 32 in a reverse process to the above, it becomes a turbulent flow due to enlargement of the cross-sectional area of a flow passage, a pressure loss is caused thereby and efficiency lowers. In order to raise a refrigerating efficiency by an increase of a heating surface area and also to reduce the pressure loss, a cold head 32 being provided with the conical part 31 with a flow passage of the fluid is used.

Title: Cylindrical rotary transformer
Inventor: HONDA HIROHIKO
IPC: G11B5/02
Filed: 1988-11-08
Abstract: PURPOSE:To prevent the leakage of magnetic flux, and to make it possible to obtain the title transformer of small size and multi-channel type by a method wherein a layer having low permeability is formed between each channel of the rotary transformer. CONSTITUTION:A layer 6E, consisting of a low permeability material, is provided between each groove 6B formed on the core 6A of a rotary transformer 6 located on the rotating side. Said layer 6E is inserted as a very thin layer between each of a plurality of coils 6C formed on the core 6A of the transformer 6. When the transfer of a signal is conducted on the channel consisting of a pair of coils 6C and 7C of the rotary transformer 7 located on the fixed side, the magnetic flux directing to the coil of the adjacent channel from the side of the coil 6C, is shielded by the layer 6E, and the magnetic flux is prevented from going further to the side of the adjacent coil. As a result, the magnetic flux generated on each channel is prevented from leaking to the adjacent channel and becomes the cause of noise, and a small-sized and multi- channeled transformer can be obtained.

Title: Surging preventing method and device for turbo compressor
Inventor: NAYA KIYOHIRO
IPC: F04D27/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the surging phenomenon by outputting a signal for closing a blow-off valve with a delay from the open signal of an inlet guide valve in shifting from unload to on-load operation, and outputting a signal for opening the blow-off valve earlier than the close signal of the inlet guide valve in the reverse transfer. SOLUTION: In the switching from unload to on-load, an inlet guide valve 1 is switched from close to open, and a first three-way solenoid valve 9 is opened by this signal to carry a pilot air to the operation part cylinder of a blow-off valve 11. At this time, the flow velocity of the air is reduced in a buffer tank, and the blow-off valve 11 is slowly closed because a delay is caused in the timing from open to close. In the reverse switching, the first three-way solenoid valve 9 and a second three-way solenoid valve 10 are closed, and the inlet guide valve 1 is switched from open to close by this signal. Thus, the surging of a turbo compressor can be prevented, and the compressor body can be protected to stabilize the air supply.
