Title: Tail pipe for supercharger of gas exhausting turbine
Inventor: FUJITSUBO ISAMU
IPC: F02B37/02
Filed: 1981-03-23
Abstract: PURPOSE:To obtain an exhaust system of little back-pressure for an internal combustion engine, by determining the external diameter of a pipe which connects a supercharger of an exhaust turbine with a silencer to be about 60mm.. CONSTITUTION:The external diameter of an exhaust pipe 7 which connects the supercharger 6 for an exhaust turbine with a silencer 9 is determined to be about 60mm., in an automobile engine, having displacement in the range of about 1,500cc through 2,800cc, and also having the supercharger for an exhaust turbine. The exhaust pipe of this kind, heretofore in use, was about 50mm. which is as same as of the one for an internal combustion engine not having the supercharger for an exhaust turbine. If a supercharger is fitted to the pipe in this size, abverse effect will be exerted to the efficiency of an engine, because the increase of displacement will cause the pipe to highten the back-pressure. The back-pressure can be reduced, by determining the diameter of an exhaust pipe to be as large as about 60mm.. However, it is not proper that the diameter will exceeds 70mm., because the pipe 7 will come in touch with a body 2 in that state.

Title: Weighting electrode for surface acoustic wave filter
Inventor: YAMADA YOSHIHIRO
IPC: H03H9/145
Filed: 1992-01-31
Abstract: PURPOSE:To set the degree of freedom of the expression of a transfer function comparatively roughly by dividing series weighting electrodes into segments each having a different interdigital width. CONSTITUTION:The interdigital width of each of divided segments is not uniform. Let cross width of each segment be Wi (i=1, 2-n), the weighting coefficient is selected to be n/SIGMA(1/Wi). In this case, the energy distribution of an excited surface wave is more or less ununiformed by changing the Wi and the weighting coefficient is selected to be optionally 0-1/n. Thus, the degree of freedom of the expression of a transfer function is set higher.

Title: Heating device
Inventor: SAKURAI MASAAKI
IPC: G03G15/20
Filed: 1982-03-16
Abstract: PURPOSE:To perform an excellent heat treatment with less power consumption and to obtain excellent fixability by heating at least one of the 1st and the 2nd rotating bodies in a heat developing device, etc. CONSTITUTION:The heating value of a heater 3 is 0-200% corresponding to respective heat generation zones and heat generation parts and has a projection at the center part on the whole. Using this heater 3 allows heat movement from the center part of a heating roll 1 to the end parts and a temperature distribution which is nearly uniform on the whole is obtained on the heating roll 1. When fixing operation is carried out in this state, no abnormal temperature rises occurs to the roll end parts even if the temperature of the heating roll drops owing to a toner image and a recording material, and the surface temperature of the heating roll is held at necessary temperature for the fixation by the heater 3. On the other hand, sleeves 15a and 15b made of heat insulating materials are fitted where bearings 12c and 12d for supporting both ends of a pressurizing roll 2 pressed against the heating roll rotatably contacts the roll and the sleeves 15a and 15b are wider than the contacting width of the bearings 12c and 21d, so even if the pressurizing roll 2 shifts in position slightly to left or right, the loss of heat conduction from end parts of the pressurizing roll 2 is eliminated.

Title: Magnetic head
Inventor: KUNITO YOSHIYUKI
IPC: G11B5/235
Filed: 1987-02-25
Abstract: PURPOSE:To improve recording and reproducing efficiency without changing the material of magnetic cores and the shape of a head by using a metallic material having <=10<-5>OMEGA.m volume resistivity for gap spacers. CONSTITUTION:The metallic material having <=10<-5>OMEGA.m volume resistivity is used for the gap spacers 2, 12 of the magnetic head which records and/ reproduces frequency signals of >=1MHz bands. The remarkable eddy current in a magnetic gap part, increased magnetic resistance and improved recording and reproducing efficiency of the head are thereby obtd. The loss by the eddy current increases in proportion to frequencies and, therefore, the improvement in the recording and reproducing efficiency particularly in the high-frequency region is remarkably high.
Patent JP-H02220113-A (JP)
Title: Temperature detecting circuit
Inventor: SAKAMOTO YOSHIFUMI
IPC: G05D23/24
Filed: 1989-02-22
Abstract: PURPOSE:To keep an amplifier analog signal at a level lower than the latch-up tolerant level of a microcomputer by applying the bias to a transistor in the forward direction via a power supply and actuating the transistor in an active area. CONSTITUTION:When an analog signal VA amplifier by an operational amplifier 2 exceeds a level obtained by subtracting the VF of a diode 12 from the radio wave voltage VDD, a transistor TR 10 is turned on an active range by the bias current supplied from the diode 12. Then the negative feedback current of the amplifier 2 flows between the emitter and the collector of the TR 10. Thus the amplification factor Af is reduced and the value of the signal VA is limited. When the value of the VA is increased more, the current flowing to the TR 10 is increased. Thus the factor Af is more reduced and the value of the VA is surely limited down to the voltage VDD or less. As a result, the potential VT of a thermistor 5 is increased after detection of a low temperature. Then an analog signal lower than the latch-up tolerant level can be inputted to an A/D port 16 of a microcomputer even though the level of the signal VA exceeds the power supply VDD of the microcomputer 1.

Title: Fuel injection device for internal combustion engine
Inventor: SOTOZONO YUICHI
IPC: F02D45/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To stop injection of fuel in a short time during the occurrence of abnormality of a fuel injection valve. SOLUTION: High pressure fuel is fed from a high pressure fuel injection pump 5 to a common rail 3 and fuel is fed from the common rail to each fuel injection valve 1. A control circuit (ECU) 20 decides the occurrence of abnormality of some fuel injection valve based on a common rail fuel pressure detected by the fuel pressure sensor 31. During detection of abnormality, the feed of fuel from the high pressure fuel pump to the common rail is stopped and infection of fuel from a normal fuel injection valve is continued. By this constitution, since fuel stored in the common rail is injected to each cylinder and discharged from the common rail, the pressure of the common rail is lowered in a short time and injection of fuel from the fuel injection valve to which abnormality occurs is completed in a short time.

Title: Light source module and optical amplifier using the same
Inventor: FUJITA MASAYUKI
IPC: H01S3/094
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent internal oscillations which become an unstable factor with respect to amplification by lowering the reflectance of light having the same wavelength band as the signal light to be amplified in optical amplification, using an optical fiber with rare-earth doped thereto. SOLUTION: Light of signal light band to be amplified the stimulation light incident from an optical fiber 3 is reflected by an optical film 6 coated on the end of the optical fiber. The end of the optical fiber is ground into a bevel, thus emitting the reflected light in radiation mode out of the core of the optical fiber. Thereby, the light reflectivity inside the core of the optical fiber is far smaller than in the case where the end of the optical fiber is processed where the end of the optical fiber is only ground into a bevel, thus incident light into the optical fiber with rare-earth doped thereto substantially becomes the only stimulation light, enabling stable optical amplification.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of forming contact holes on an interlayer insulation film to simplify the process by selectively oxidizing a conductive film formed on a substrate to form electrode leading parts, except the upper part of external connections at a semiconductor element region. SOLUTION: A semiconductor element region is formed on the surface of a substrate 2.
