Title: Ultrahigh frequency signal changeover equipment
Inventor: YASUDA MASAKATSU
IPC: H03F3/72
Filed: 1986-01-13
Abstract: PURPOSE:To prevent the deterioration of a noise index by adding a high frequency amplifier between an output of a changeover circuit used as a signal changeover means and a signal output terminal of a metallic case in the metallic case. CONSTITUTION:A bipolar DC control voltage is fed from a signal switching control terminal 5 in a changeover circuit 1, any signal from signal input terminals 3a, 3b passes through by conducting/cutting-off high frequency switching diodes 4a-4d to send a signal to a point A. Further, a signal is amplified by a high frequency amplifier circuit 2 and a signal is extracted from an output terminal 11. Further, the adverse effect of a standing wave ratio of a signal output terminal due to the buffer effect of the circuit 2 onto the terminals 3a, 3b from the terminal 11 is prevented.

Filed: 1986-01-13
Abstract: PURPOSE:To arrange an electrode of narrow width by forming an opening on a resist on a substrate and depositing a width controlling film in it from an oblique direction. CONSTITUTION:On a semi-insulating GaAs 1, an N<-> buffer layer 2, an N-active layer 3, and N<++> high conductive layer are formed by gas-phase epitaxy. Source and drain electrodes 5 and 6 are arranged by continuous evaporation of AuGe- Ni-Au and a resist mask 7 is applied. A substrate is set in an electronic cyclotron resonance plasma CVD device 20 having a deposition directivity and SiH4 and O2 are flowed and a high-frequency power is applied to deposit an SiO2 8 obliquely which narrows a width of an opening. A groove 9 which reaches the active layer 3 from the opening is formed by means of an etching solution of tartaric acid group. Next, Al is evaporated by using the SiO 8 as a mask to form a gate electrode 10 whose width is narrower than the opening width of the resist 7. Lastly, the resist 7 and the SiO 8 are removed to complete an FET. By repeating the oblique deposition two times, the gate electrode can be formed near the center.

Filed: 1992-01-14
Abstract: PURPOSE:To inhibit the operation frequency of a high voltage cut-off device and enhance reliability by deciding an operating condition which allows the protection control of an operation control device to work at an earlier stage than the time im posed by the operating condition when driving the high voltage cut-off device which suspends the operation if the pressure of refrigerant exceeds a specified value and storing the condition. CONSTITUTION:The operation of an indoor unit 10 and an outdoor unit 11 of an air conditioner is controlled by their respective operation control devices 20 and 21 incorporated in each of the units 10 and 11. A refrigeration compressor 13 of the outdoor unit 11 is forced to stop its refrigeration operation by a high voltage cut-off device 25 when the refrigerant pressure of a discharge pipeline of the refrigeration compressor 13 exceeds a design value. In this case when the high voltage cut-off device 25 operates in terms of the operation control unit 20 of the indoor unit 10, an attempt is made to set a condition which operates an excess pressure rise preventative control operation earlier than the cut-off condition and store the condition in memory. A command based on the stored condition is transmitted to the operation control device 21 so that an excess pressure rise preventative control operation may be carried out so as to halt the operation of the refrigeration compressor 13.

Title: Manufacture of pneumatic tire
Inventor: FUKUOKA SATORU
IPC: B29C35/04
Filed: 1984-01-13
Abstract: PURPOSE:To suppress the production of a bulge and a dent at a new tire time and suppress the growths of them by inserting a bladder into a tire after vulcanization, applying an internal pressure to the bladder and cooling the tire in the state supported in a swelled state. CONSTITUTION:When a tire 21 after vulcanization is moved on a conveyor 20 and stopped at the position contacted with a stopper 23, upper and lower units 10a, 10b approach, the tire 21 is interposed between upper an lower rims 13, 27 and compressed air is supplied into the bladder 15 through the vent hole 29 of an upper board 12. Thus, the bladder 15 is expanded, contacted with the inner surface of the tire 21, and holds the tire 21 by the internal pressure in the expanded state. When the state is retained until the tire is cooled, the thermal contraction of the cord is suppressed. Since the tire is pressurized through the bladder 15 contacted with the inner surface of the tire, the difference of the elongation and contraction of the joint and nonjoint portions can be reduced. Thus, a buldge and a dent amount of new tire time can be suppressed to low values. Since a load is applied to the cord, the growths of the buldge and the dent due to long time traveling can hardly occur.

Title: Semiconductor device and its manufacture
Inventor: MIYAMOTO SHOICHI
IPC: H01L21/84
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To suppress the leakage between source and drain electrodes by forming sidewalls under the gate electrode, and forming it from the height of a conductive layer acting as a part of the gate electrode effectively to the height of the bottom surface of an SOI layer. SOLUTION: A conductive layer 5 is formed above an SOI layer 3, and constitution is so made that this conductive layer 5 may act effectively as a part of a gate electrode. Sidewalls 8 are formed higher than the upper surface of the SOI layer 3, suppress the decrease of the distance between the top end part of the SOI layer 3 and a gate electrode 10, and maintain the distance between a surface opposed to a channel of the gate electrode 10 and the upper surface of the SOI layer 3 equal. Consequently, it becomes possible to suppress field concentration and the leakage between the source and drain electrodes.  Besides, the surface of the SOI layer is not damaged by etching, since a gate insulating layer 4 and the conductive layer 5 have been formed on the SOI layer 3 before the patterning of the side cross sections of that layer, and no etching processes are performed to the surface of the SOI layer 3.
