Title: Bland and manufacture of bolt with same blank
Inventor: KAJINO HIROSHI
IPC: B21H3/02
Filed: 1990-06-06
Abstract: PURPOSE:To improve the first thread-cut portion of a screw thread at the tip of a blank by slightly inclining a boundary face between a large diameter part to be thread-rolled and a small diameter part at its tip to a plane perpendicular to the axis of the blank. CONSTITUTION:The tapered boundary face 3 of a connecting part between a large diameter part 1 to be thread-cut by thread rolling and a small diameter part 2 to serve as a guiding part for the tip of a bolt is slightly inclined to a plane 5 perpendicular to the axis of a blank 4. Thus the first thread-cut portion of a screw thread at the tip of the blank can be improved for the excellent leading of the screw thread into a female screw.

Title: Transistor amplifier
Inventor: FUNAHASHI MASAHIRO
IPC: H03F3/19
Filed: 1985-07-08
Abstract: PURPOSE:To drive sufficiently a transistor (TR) at an output stage by providing the connection of an emitter resistor and 2 level shift diodes in series to an emitter of an emitter follower TR of the next stage. CONSTITUTION:A TR 1 constitutes an input stage common emitter circuit, a TR 2 constitutes a next stage emitter follower circuit and a TR 3 constitutes a common emitter circuit at the output stage using a choke coil as a collector load. In forming the emitter follower where the series connection of the emitter resistor 9 and the level shift diodes 13, 14 is provided to the emitter of the TR 2, even when the resistance of the resistor 9 is decreased, the emitter current flowing to the TR is unchanged. That is, the resistance of the resistor 9 is decreased without changing the emitter current flowing to the TR 2. Thus, the time required for discharge is reduced and the decrease of the base voltage of the TR 3 is attained sufficiently even at a high frequency so as to prevent the decrease in the output power.

Abstract: PURPOSE:To shape the asymmetricity of the leading edge and trailing edge of a reproducing pulse at the output side of adifferential amplifier by providing a means amplifying a reproducing signal from one MR film so as to eliminate the characteristic difference of the 1st and 2nd MR films. CONSTITUTION:An attenuator 12 is used and the ratio of the reproducing sensitivity of the 2nd MR film 3 to the reproducing sensitivity of the 1st MR film 2 is used as a gain of the attenuator 12. Thus, an output signal of the attenuator 12 has equal amplitude to that of an output signal at the 2nd output terminal 7. Thus, no asymmetricity in the leading/trailing edge is caused in a reproduction pulse.

Title: Polling bearing
Inventor: TERASAKA HIDETOSHI
IPC: F16C35/04
Filed: 1980-10-24
Abstract: PURPOSE: To facilitate a complete grease replacement and bearing replacement by interposing a spherical seat between an outer ring of a rolling beating for a reactor cooling fan an two-divided bearing box to bring the inner surface of the bearing box into contact with the outer peripheral surface of the sperical seat in a spherical surface.  
     CONSTITUTION: A spherical seat 4 is interposed between an outer ring 1a of a rolling bearing 1 and a bearing box and the outer peripheral surface 4b of the spherical seat 4 is formed in a spherical surface. The inner peripheral surface 3c of the bearing box 3 has the same curvature as the outer peripheral surface 4 of the spherical sheat 4, whereby the inclination of a rotarory shaft 2 forces the bearing 1 to incline along the spherical part 3c through the sperical seat 4, resulting in automatically controlling the center of the bearing 1. Thus, a complete grease replacement can be easily accomplished at the time of periodical check, and at the time of exchange of a bearing, a conventionally available bearing can be used as it it. No other parts then the rolling bearing are necessary to be exchanged, so the exchange of bearing can be easily done.

On the other hand, actuator 11 includes a couple of fixed magnetic poles 18, 18 around which coil 19 is wound in the manner facing the plane in which tops of rotor 14 are passed. When current is passed through the coils 19, rotor 14 is moved to a position where its opposite ends face correctly with the fixed magnetic poles 18, 18.

Abstract: PURPOSE:To prevent the generation of picture deformation, by using a signal multiplying a synchronizing signal of a still picture signal, detecting a frequency of a clock signal and controlling the amount of drive of a form sheet, in a device printing the still picture signal with a heat-sensing head. CONSTITUTION:A horizontal synchronizing signal HD from a separation circuit 3 is applied to a PLL circuit 26 to form a reference signal Sx, which is applied to a clock terminal CK of a counter 4b. Further, a signal being a period (16 musec) from the horizontal synchronizing signal HD to the left end of the effective screen is formed by counting the signal at the counter 4b by 16-count. Then, a picture element clock signal SC1 is applied to a counter 27 and a reference signal Sx is applied to a reset terminal of the counter 27. Thus, a frequency value of the clock signal SC1 is detected at the counter 27, the value is applied to a frequency-division circuit 23 to control the frequency dividing ratio, and the amount of drive of a platen 20 is controlled while one picture element is printed. The profile of picture is made constant at all times by adjusting the amount of drive.

Title: Conductive fine powder and its manufacture
Inventor: HIRATA HIROKI
IPC: H01B1/00
Filed: 1995-06-15
Abstract: PURPOSE: To enhance stability with the lapse of time of a dispersing liquid by obtaining antimony dope tin oxide type conductive fine powder having a small particle diameter by low temperature water heat treatment. CONSTITUTION: Conductive fine powder composed of particles containing an antimony dope tin oxide and a surfactant is manufactured by heating liquid containing a tin compound, an antimony compound and surfactant in a pressure vessel. When the surfactant is added to solution containing a tin compound and an antimony compound, since wettability of a particle surface to a solvent is improved, dispersibility is enhanced, and since reaction is promoted thereby, water heat treatment can be performed at a low temperature. Since dispersibility of the tin and antiomony compounds is improved, conductive fine powder having an average particle diameter not more than 100nm can be obtained only by adding the surfactant.  In the obtained conductive fine powder, since the surfactant is stuck to a particle surface, when this is formed as a dispersing liquid, coagulation is hardly caused over a long period of time.
