IPC: B25F5/00
Filed: 1995-03-23
Abstract: PURPOSE: To surely prevent a heat-radiating fin from floating up by forming a recess in the heat-radiating fin, and forming a projection that can engage in the recess, on a rib provided on an outer frame, in a power tool in which the heat-radiating fin is enclosed in a space formed between the outer periphery of a motor and the internal wall of the outer frame. CONSTITUTION: A motor 2 and a shift switch 3, etc., are enclosed in an outer frame 1 divided into two, and a FET 4 connected to the shift switch 3 by a lead wire and a heat-radiating fin 5 tightened to the FET 4 by a screw are enclosed in a space between the internal wall of the outer frame 1 and the outer periphery of the motor 2. A recess 5a is formed in the heat-radiating fin 5, and a rib 6 made of an elastic material provided at its end with a projection 6a to be engaged in the recess 5a is formed integral with the outer frame 1. Therefore when the heat-radiating fin 5 is enclosed in the outer frame 1, the recess 5a in the heat-radiating fin 5 is engaged with the projection 6a of the rib 6 to surely prevent the heat-radiating fin 5 from floating up.

Abstract: PURPOSE:To produce blow sounds as well reverberating bass, to improve the production of the blow sounds, to prevent deformation of a mouthpiece, to obviate leakage of sounds and to improve assembling and working properties by forming a tuning part on the inner side of the flat part of a semi conical cylindrical loud-speaking part of main bodies and allowing the flat part of the semi-cylindrical mouthpiece to remain. CONSTITUTION:The tuning part 5 is recessed and formed in such a manner that the flat surface 2b remains around the flat part on the inner side of the flat part of the semi conical cylindrical loud-speaking part 2 of the main bodies 1 of a megaphone formed by connecting two pieces of the main bodies 1 formed to the semi conical cylindrical shape freely openably and closably at one point 6. As a result, the bass reverberating better than heretofore is obtd. The flat part 2b around the tuning part 5 acts as a reinforcing section to improve the production of the blow sounds. The flat part, circumference and base end side of the mouthpiece 3 act as the reinforcing sections to prevent deformation of the mouthpiece 3 and are, therefore, capable of preventing the leakage of the sounds. Further, the assembling and working properties are improved by connecting the connecting section to a spring pin.

Abstract: PURPOSE:To attain the interpolation of the output of failure picture elements without the need of a complicated arithmetic circuit by interpolating the fault of a video signal due to the fault picture element by means of the normal picture element near the fault picture element. CONSTITUTION:An output signal from an image pickup plate is synchronized with a vertical transfer clock and a horizontal transfer clock, and is outputted. Counters 1 and 4 count the vertical transfer clock and the horizontal transfer clock. The vertical address of the fault picture element is written in a ROM2, and the horizontal address of the picture element adjacent to the fault picture element in ROMs 5 and 6 after checking. The output of an AND circuit 16 becomes H while the fault picture element is checked. with the output, switching circuits 17 and 18 switching-operate. The switching circuit 17 switches A and B at every frame, and the switching circuit 18 is switched to D while the fault picture element is checked, and to C excepting that. Thus, the fault picture element is interpolated by the normal and adjacent picture element.

Abstract: PURPOSE:To form on a semiconductor surface an insulation film of good quality excellent in the resistance to hot carriers, by forming an oxide film by thermal oxidation of the surface of a semiconductor substrate and thereafter heat- treating the semiconductor substrate in a gaseous atmosphere containing carbon, thereby reducing the interface level and fixed charge. CONSTITUTION:In a manufacture of a semiconductor device which includes a process for oxidizing the surface of a semiconductor substrate thereby to form an oxide film, after the formation of the oxide film, the semiconductor substrate is heat-treated in a gaseous atmosphere containing carbon. For instance, if the oxide film is formed on a silicon substrate, after washing with a chemical liquid as the conventional pretreatment, the oxide film is formed to a thickness of 200 Angstrom  by an oxygen gas diluted with nitrogen. Thereafter the oxidizing atmosphere is changed from the oxygen gas diluted with nitrogen to a carbon dioxide gas, and a heat treatment is carried out. The temperature of the heat treatment is set to 900 deg.C. In this case, the measurement of the concentration distribution of carbon elements in the oxide film using SIMS provides a result as shown, for instance.

IPC: F02D41/00
Filed: 1987-03-19
Abstract: PURPOSE:To prevent considerable shift of air-fuel ratio by varying the upper limit being set on a detection value of intake air quantity or operated fuel injection quantity according to the temperature of combustion chamber. CONSTITUTION:Injection quantity of a fuel injection valve 25 arranged in an intake path 12 is controlled by a controller 100 which receives intake air quantity signal from an air flow sensor 20. The controller 100 receives a signal from a water temperature sensor 24 and varies an upper limit being set on a detected intake air quantity signal or an operated fuel injection quantity according to cooling water temperature.

Title: Mobile radio communication system
Inventor: SHIBANO YOSHIZO
IPC: H04W76/02
Filed: 1987-03-18
Abstract: PURPOSE:To keep high transmission quality by using an antenna of a ground stationary station as a circularly polarized wave downward beam antenna an adopting an upward beam antenna for an antenna of a mobile body to select a circularly polarized wave in any rotating direction. CONSTITUTION:An antenna 2 installed on ground radiates a circularly polarized wave rotated to the right or left and an antenna 2' installed on ground radiates a circularly polarized wave rotated in the inverted direction to that of the antenna 2. On the other hand, an on-vehicle antenna 4 of a vehicle 3 receives a circularly polarized wave rotated in any direction and receives only any circularly polarized wave selectively. Thus, the antenna 4 mounted ON the vehicle 3 does not receive a signal reflected in a building or a road and led horizontally or downward. Since the rotation direction of the circularly polarized wave of the adjacent antenna installed on ground is set oppositely to each other, the reception of the direct wave from other adjacent ground installed antenna is prevented.
