Title: Screw and driver bit
Inventor: NOJIGAWA TERUFUMI
IPC: B25B15/00
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a screw and a driver bit free from the come-out phenomenon. SOLUTION: A point side part 10a of at least one sidewall surface 10 of a blade engagement part 2 capable of fitting a blade of a driver bit is bent with respect to a basic end part 10b of the side wall surface 10, to be separated from the sidewall surface on the opposite side in a rotary part 5 formed overall into the shape of a cave-in. The driver bit is formed into the shape corresponding to the rotary part 5. Whereby the driver bit hardly inclines to a screw 3, further the sidewall surface 10 of the blade engagement part 2 of the bent screw 3 bites the corresponding bent side surface of the blade of the driver bit, so that the sidewall surface 10 is surely grasped by the side surface, and a blade part 8 and the blade engagement part 2 are effectively engaged with one another, whereby the driver bit hardly comes out.

Abstract: PURPOSE:To obtain a highly efficient high frequency snubber circuit by recovering energy stored in an anode reactor as well as a capacitor and canceling the flux on the secondary winding side through excitation of a reset winding thereby preventing the core of a transformer from saturation. CONSTITUTION:When a semiconductor element 4A is turned OFF and a semiconductor element 4B and an auxiliary semiconductor element 10B are turned ON, a capacitor 1A starts to be charged while a capacitor 18 starts to be discharged. Since the capacitor 1B has previously been charged with the energy of an anode reactor 9B, energy of the anode reactor 9B can also be recovered. A reset circuit 13B then excites a reset winding 12B to cancel the flux induced in the secondary winding of a transformer 3B at the time of regeneration under a state where the auxiliary semiconductor element 10B is turned OFF and the primary winding of the transformer 3B is separated from the capacitor 1B.

IPC: F23D14/18
Filed: 1990-02-19
Abstract: PURPOSE:To reduce a discharging of unburnt combustible gas and prevent an efficiency of combustion from being reduced by a method wherein a cross sectional area of a gas inlet part of a catalyst container is made smaller than a cross sectional area of a gas outlet port and formed to expand toward the gas outlet port. CONSTITUTION:A catalyst container 2 is comprised of a tapered pipe 11, and porous heat-resistant supporting members 12 and 13 closing both end openings capable of making a free passage of gas to constitute a gas inlet port and a gas outlet port, respectively. The tapered pipe 11 is formed such that a cross sectional area A of the gas inlet port, i.e. the supporting member 12 is smaller than a cross sectional area B of the gas outlet port, i.e. the supporting member 13 and the tapered pipe is formed to expand toward the supporting member 13 at the gas outlet port. In this way, the catalyst container 20 is formed as an expanding cylinder, thereby a tablet type combustion catalyst can be used as it is even in an application requiring a reduced pressure loss, resulting in that a discharging of the not-yet-ignited combustible gas is reduced and a combustion efficiency is prevented from being decreased.

Title: Electron lens with deflector
Inventor: KATAGIRI SHINJIROU
IPC: H01L21/027
Filed: 1978-03-29
Abstract: PURPOSE: To reduce the working distance and to imporve the performance of the drawing unit, by combinating the deflector with the objective lens magnetic electrodes.  
     CONSTITUTION: The lower magnetic field 10A is made of the ferromagnetic substance which has fast response to high frequencies (such as ferrite) and the thickness of the magnetic poles and the spacer can be reduced by using it as a part of the deflection yoke. Accordingly, the working distance D of the objective lens can be reduced and the fast response can not be lost. Or, the yoke enclosing the most part of the deflection coil 13 is formed with the lower magnetic pole 10B and it is acted like the objective lens magnetic pole. Although the deflection coil is within the converged magnetic field of the objective lens, since the operation is independent, mutual effect is less. Thus, D is equal to the working distance S of the deflection coil and it is ideal. It is further effective when the upper magnetic pole 7A is partly replaced with ferromagnetic substance.

Abstract: PURPOSE:To secure the easy reduction of the interference wave by installing the prescribed wave absorber to the effective area antenna. CONSTITUTION:The wave absorber is installed in region DELTAS which is part of reflector surface S of the effective area antenna, and both the position and form of region DELTAS are set so that radiation field E(theta) may be almost zero in direction theta where the reduction of the side lobe is desired, i.e., the conditions of the equation may be satisfied. In that case, f(s) is the main reflector surface field distribution, lambda is the wavelength, R is the distance between the centers of the transmission and the reception antennas, K is the wave number, and r(s) is the distance from region ds through the center of the reception antenna respectively. In such way, wave absorber 22 is installed on reflector surface 20 of the parabola antenna for example, thus giving reduction to the interference wave in the easy way. Furthermore, if the position of the wave absorber is set adjustably, the side lobe level can be reduced in the optional direction.

Filed: 1986-02-21
Abstract: PURPOSE:To select a reception system with a large instantaneous CNR at all times by shifting a level detection characteristic excellent in sensitivity toward the lower reception level by the difference of sensitivity so as to decide the quantity of the instantaneous CNR. CONSTITUTION:Signals Sa, Sb received by reception antennas 1a, 1b are sent to detection sections 4a, 4b via RF IF sections 2a, 2b. A comparator 5 compares outputs of level detectors 3a, 3b to throw a changeover switch 6 to the reception system larger in level. The level detection characteristic of the better reception sensitivity is shifted to a lower reception input level depending on the reception sensitivity difference of the reception system in the level detection characteristic of the level detectors 3a, 3b. As a result, the comparator 5 selects the reception system having a large instantaneous CNR to change over the switch 6.
