Title: Semiconductor device
Inventor: FUKADA MASAKAZU
IPC: H01L21/52
Filed: 1985-02-27
Abstract: PURPOSE:To diminish the unevenness of distribution in contact pressure in the first electrode surface of a semiconductor element, and to enable the inexpensive supply of the title device, by a method wherein the first electrode side copper post electrode is constructed by splitting into a copper electrode base part and a copper post block. CONSTITUTION:The cathode side copper post electrode is splitted into a copper post block 4 provided with a control electrode wiring lead-out guide groove 8 and a cathode side copper electrode base part 11 to be fixed to a flanged ceramic package 9. Assembly is carried out by a method wherein the flange of said base part 11 is fixed by welding to a ceramic package 9. This construction causes no distribution of the unevenness of contact pressure is the first electrode surface of the semiconductor element because of no guide grooves in the surface of the first electrode side copper post electrode which contacts the semiconductor element via the first electrode side electrode plate. Besides, the producing cost can be reduced because of only the need to change the copper post block according to the system of control electrode wiring lead-out of the semiconductor element.

Title: Burning condition setter for proportional control type burner
Inventor: KUWABARA HIDEHIKO
IPC: F23N1/00
Filed: 1994-02-15
Abstract: PURPOSE:To reduce possibility of insufficiency of an input port by decreasing the number of ports of a microcomputer needed by a burning condition setter as much as possible. CONSTITUTION:Variable resistor voltage dividers 2 and 3 for applying maximum and minimum combustion rate signals VMAX, VMIN are respectively connected to two input ports 6 and 7 of a microcomputer 1 as a combustion rate controller. Further, switches 4 and 5 for applying 0V to the ports are respectively connected to the two ports 6 and 7. When the switch 4 is closed, the microcomputer 1 becomes a minimum combustion rate set mode. The minimum combustion rate can be set by regulating the output voltage VMIN of the divider 3. When the switch 5 is closed, a maximum combustion rate set mode is obtained, and hence the maximum combustion rate can be set by regulating the output voltage VMAX of the divider 2 at this time.

Title: Measurement of atmospheric pressure utilizing measurement of intake pipe negative pressure
Inventor: MITANI TATESHIRO
IPC: G01L23/24
Filed: 1987-02-23
Abstract: PURPOSE:To realize an inexpensive, space saving and accurate atmospheric pressure measuring method by reading the maximum ripple value of the output of a boost sensor for measuring intake pipe negative pressure when the outputs of a variety of sensors become predetermined conditions. CONSTITUTION:An instrument is composed of a variety of sensors, such as a throttle opening sensor 5, a boost sensor 6, an intake air temperature sensor 7, an engine water temperature sensor 8 and the like. The outputs of those sensors are inputted to a CPU 12 and the operating condition of an engine is discriminated. Thus, the power waveform of the sensor 6 at some operating condition is inputted to the CPU 12, converted to a mean voltage by a smoothing circuit and read as a prescribed pressure value. When a valve for making a mixed gas flow into the cylinders of the engine 10 is opened (or closed), the output of the sensor 6 takes the minimum (or maximum) ripple value. The maximum ripple value is determined by an engine speed, the opening of a throttle valve 4 and the other temperature conditions of the engine. In the operation of the engine, the maximum ripple value represents a value near that of the atmospheric pressure and, when the engine is set to the same condition, an atmospheric pressure condition can be detected.

Abstract: PURPOSE:To attain accurate color reproduction by inputting all colors perceived by human being to the system. CONSTITUTION:A sender side device 100A receives a color signal representing combinations of three primary colors each represented by apexes of triangles whose one side in three sides at least is circumscribed substantially with a spectrum locus of a prescribed chromaticity diagram. Then, an original color area discrimination circuit 103 discriminates a color area and a coordinate conversion section 102 converts a coordinate of an inputted color signal into a coordinate in response to the discriminated color area and a communication control section 106 sends the color signal subject to coordinate conversion. A receiver side device 100B applies color correction to the color signal received by a color correction section 109 and outputs the result from an output section 110.

Title: Car air conditioning device
Inventor: TAMARU SEI
IPC: B60H1/00
Filed: 1984-03-02
Abstract: PURPOSE:To decrease the volume of an inside and outside air switching box containing a damper therein and especially the height thereof, by a method wherein the length L1 of the damper is set to a value approximately equal to width L2 of the opening and closing port of an air inlet. CONSTITUTION:When a damper 5 is swung by about 45 deg. rightward or leftward around a rotary shaft 4, the damper is brought into contact with opening and closing ports 1a and 2a of an inside and outside air inlet to close the openings. length L1 of the damper is set to a value equal to width L2 of the ports, and thereby the ports are completely closed. When the dapmer is swung rightward to introduce the outside air, the damper is moved as it is limited by a guide rail 6 so that the forward end thereof is prevented from collision with the bottom surface of a box and the rear end of the damper is swung leftward along the rotary shaft 4 such that a guide rail 7 for a shaft slinding, extending in the longitudinal direction of a plate surface, prevents collision of the damper with a length L1, sized to be longer than height L3 of the box, with the box. This permits reduction of the volume of an inside and outside air switching box, especially the height thereof.

Title: Electrode for treatment
Inventor: SUGIMOTO TAKETO
IPC: A61N1/32
Filed: 1992-02-27
Abstract: PURPOSE:To obtain the electrode for treatment which can make a local thermotherapic treatment by coming into tight contact with an affected part and allows the easy exchange of a part in contact with the affected part by forming a heating element to be stuck to the electrode of a wire part which generates heat when a current is passed therein and wiring the central part of the wire part densely and the circumferential part coarsely. CONSTITUTION:The pattern of the wire part 3 of the heating element 2 is so formed that the density of the central part is higher than the density in the circumferential part. The current flows via cords 4, 6 respectively to the heating element 2 and an electrode sheet 5. In succession, the electrode 8 is stuck to the affected part when a tacky adhesive conductive pad 7 rises to an adequate temp. The electric treatment and thermotherapic treatment are thus carried out. The central part of the tacky adhesive conductive pad 7 rises to the temp. higher than the temp. in the circumferential part at this time. Only the tacky adhesive conductive pad 7 is peeled from the electrode sheet 5 and is exchanged with a fresh pad when the tacky adhesive conductive pad 7 comes to be stained. As a result, the treatment effect is enhanced and the hand of use is improved.
