Abstract: PURPOSE:To protect a drive circuit upon short-circuit of a fuel injection valve, by delivering a signal voltage given to the drive circuit and a voltage imposed to the fuel injection valve, to a logic circuit so that the energization of the fuel injection valve is ceased during the operation of a timer circuit. CONSTITUTION:An AND circuit receives a signal voltage Vi, a voltage which is obtained by inverting a voltage Vo imposed to a fuel injection valve through, a NOT circuit, and a voltage which is obtained by inverting the output of a monostable multivibrator OSM through a NOT circuit. Upon short-circuit of the fuel injection valve the output of the AND gate is turned into H-level from L-level, and therefore, the monostable multivibrator OSM is triggered so that the output thereof is turned into H from Q for a predetermined time. Accordingly, a transistor Tr 4 is turned on while a transistor Tr 2 is turned off so that the injection valve is deenergized. With this arrangement, no power transistors are failured, and as well no heart is generated in association with protection against short-circuit, thereby the device may be miniaturized with an enhanced reliability.

Abstract: PURPOSE:To obtain an element isolation region, whose width is narrower and surface is flat, for the substrate of a semiconductor device by a method wherein an aperture is commonly opened in two films of an SiO2 film and an Si3N4 film, and after that, the Si3N4 film is subjected to an etching on the side thereof and a groove is formed in the Si substrate after the etching was performed, or, at the same time as a time when the etching is performed. CONSTITUTION:An aperture is commonly opened in two films of an SiO2 film 2 and an Si3N4 film 3, both formed on an Si substrate 1 using a resist mask 12. The composition, flow and pressure of etching gas are selected and a groove 4 is formed in the substrate 1 by performing isotropically a plasma etching. Following that, the resist mask 12 and the SiO2 film 2 are removed, a thermal oxide film 5 is formed on the inner sidewall of the sidewall of the groove 4 and the whole surface of the groove 4 is covered with a CVDSi3N4 film 6. When an RIE is performed, the short part of the Si3N4 film 6 remains on the side surface of the groove 4, because each overhang 7a of the Si3N4 films 3 and 6 is short. When a selective oxidation is performed in such a condition that the extension of the bird's beak of the sidewall of the groove 4 is stopped at the terminal part 10 of the element region, the SiO2 film 2 of a bird's beak forming part 9 becomes thicker and a recessed part 11 is reduced. As a result, an almost flat element isolation oxide film is obtained.

Title: Impressing tool
Inventor: HAMAI TOSHIYA
IPC: B41K1/44
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To ensure a predetermined ink discharge when a predetermined or more pressing force is given and to eliminate excess discharge of ink by using a space formed between a body inner wall and an ink occlusion material as a temporary ink release part for oozing out the ink at the time of pressing. SOLUTION: An ink occlusion material 2 is formed at an upper surface for receiving a pressing force in a convexo-concave surface so that concave parts are used as temporary ink release part 2a. That is, when the force is given, the material 2 is entirely reduced in volume corresponding to a pressed length. If ink is occluded to be saturated, the ink of an amount corresponding to the reduced volume is released from the material, and ink at a periphery of the convexo-concave surface of part of the released ink is temporarily discharged to the part 2a. In this case, since the partial ink is always discharged to the part 2a, a danger of excess discharge is suppressed as much as possible. Thus, unclear printing mark due to insufficient pressing force is eliminated.

Title: Mixing circuit of tuner
Inventor: UMEMURA YOSHIHARU
IPC: H04B15/06
Filed: 1982-03-05
Abstract: PURPOSE:To improve the voltage leaked out of an antenna terminal of a tuner as well as the undesired radiation, by reducing only the locally oscillated higher harmonic component in the locally oscillated frequency components which are injected to a mixing circuit. CONSTITUTION:An interstage circuit 1 is synchronized with the RF frequency and therefore becomes capacitive with a frequency higher than the RF synchronizing frequency. At the same time, an LPF is formed at an input part of a mixing circuit 3. Therefore only the locally oscillated higher harmonic component which is injected to the circuit 3 can be reduced by selecting the constant of a coil 9 and a capacitor 10 so as to obtain the pass band characteristics as shown by a diagram. Thus it is possible to improve the voltage leaked out of an antenna terminal of a tuner as well as the undesired radiation.
