Title: Eliminating device of switching noise
Inventor: UCHIKOSHI KOUJI
IPC: G11B20/24
Filed: 1983-02-01
Abstract: PURPOSE:To obtain a playback sound signal which is highly faithful to an original sound having no switching noise by a helical scanning system by equalizing signal voltage differences at connection parts of signals originating from the offset voltage difference and sensitivity difference between demodulation circuits. CONSTITUTION:A correction control system for the offset voltage difference has the 1st sample holding circuit 71 and 2nd sample holding circuit 72. The 1st sample holding circuit 71 holds the offset voltage of the demodulation system of a rotary head 12 in a nonactive period right before the active period of the rotary head 11 starts and inputs the voltage to one terminal of a differential amplifier 8 in response to the fall of a control signal S3 from H to L, and the 2nd circuit 72 inputs the voltage of the voltage right before the active period of a rotary head 12 starts to the other terminal of the differential amplifier 8 in response to the H-to-L fall of a control signal S3. The differential amplifier 8 outputs the difference signal corresponding to the level difference between both offset voltages and an adding circuit 10 adds it to the output of the demodulation circuit corresponding to the rotary head 12 so that the level difference between both offset voltage is eliminated, thus correcting the level difference between both demodulation outputs.

Title: Lubricant mixing device of fuel tank for 2-cycle engine
Inventor: KOBAYASHI SUMIOU
IPC: F02M37/00
Filed: 1981-02-05
Abstract: PURPOSE:To make it possible for a fuel tank to automatically blend oils at a prescibed ratio, at the time when the fuel tank is supplied with fuel, by supplying the tank with a lubricant from a separate lubricant tank in proportion to volume of the fuel. CONSTITUTION:At the time when a fuel tank 1 is replenished with fuel, the level in the tank rises with supply of the fuel, and the level in a pressure chamber 2 also rises. And, air is compressed by pressure of head H1, and a lubricant in a lubricant tank 4 is pushed up to a lubricant tube 6. On the other hand, a venturi 8 of an injection tube 7 is under a negative pressure by flow speed of the fuel being injected, and therefore, the lubricant flows to the lubricant tube 6 and flows over to the venturi 8 to be mixed up with the fuel. Once the lubricant started flowing into the lubricant tube 6, it keeps flowing continuously by syphonal effect. When flow of the lubricant and negative pressure in the lubricant tank 4 are equilibrated at a head H2, the lubricant stops flowing.

Title: Multiplet scissors mounting device
Inventor: JIYON RUDORUFU MENJISU
IPC: A61B17/128
Filed: 1983-02-03
Abstract: A multiple clip applier including a handle and a cartridge which holds a large number of ligating clips and which snaps into a cartridge-receiving channel on the handle. The handle operates like an elongated scissors with scissors handles at one end and jaws at the other to which clips may be delivered in rapid succession. Opening and closing the scissors handles operates the mechanism of the handle to open and close the jaws and to provide a long stroke motion for delivering clips from the end of the cartridge to the nose section. Clips may be indexed through the cartridge by reciprocating parts of the cartridge with respect to one another with a short stroke cocking motion captured from the long stroke delivery motion from a cooperating slot and pin mechanism. These two motions are accomplished within the envelope of motion of the normal opening and closing of the scissors handles to operate the jaws of the applier and to feed and index clips from the cartridge to the nose. The mechanism of the present invention permits the overall shape of the handle to be small, compact and readily adaptable for use even deep in an incision site.

Title: Electronic choke circuit with electric current limit function
Inventor: SUMIDA TETSUAKI
IPC: H04Q3/42
Filed: 1986-01-29
Abstract: PURPOSE:To eliminate a choke coil and to miniaturize a circuit and to package the circuit with high density by providing an electric current limit circuit function to give the electric potential difference between base emitters of a transistor for a direct current limit with the voltage drop of an electric current detecting resistance. CONSTITUTION:At a trunk line trunk COT, an alternate current component (sound signal) on a telephone line L is inputted through a capacitor C to an exchanging switch SW. A choke circuit CH does not pass an alternate current component, passes only a direct current component and forms a direct current loop. The direct current resistance of the choke circuit CH is R=RB/hfe+Rs, an alternate current impedance is RB+iwC0, and when an electric current amplifying ratio hfe is made larger, a base resistance RB comes to be also larger, and therefore, the alternate current impedance can be made larger without enlarging the direct current. Since the electric current limit circuit is formed by a transistor Q3 and a resistance Rs, the direct current between electric current paths 1 and 1a is limited.

Title: Positioning device
Inventor: INOUE HIROSHI
IPC: B23Q5/40
Filed: 1988-01-28
Abstract: PURPOSE:To make it possible to perform plural positioning operations with a single drive means so as to reduce the weight and the cost of the device in the caption by properly operating each control means relating to a drive shaft which is driven by the single drive means, CONSTITUTION:While a nut member 22 is allowed to rotate around its axis, and a control means 34 for controlling movement in axial direction is operated, another control means 54 for controlling the movement of a rotary body 30 which is connected to the nut member 22 so as to be integrally rotated, is made non operative. And when a ball thread shaft 18 is rotated by a servo motor 14, the nut member 22 is allowed only to rotate around the axis, so that movement corresponding to the rotation quantity of the servo motor 14 is applied to the connected rotary body 30. On the other hand, when the control means 34 is made non-operative, and the control means 54 is operated, the rotational movement of the rotary body 30 is limited, and the rotation of the nut member 22 is restricted, so that the movement of the ball thread shaft 18 in its extending direction, corresponding to the rotation quantity of the servo motor 14, is applied to the nut member 22, consequently, more than two positioning operations can be attained with the single servo motor 14.

Title: Guide mechanism
Inventor: HASEGAWA TADASHI
IPC: G11B21/16
Filed: 1985-01-30
Abstract: PURPOSE:To obtain a guide mechanism having high accuracy and low cost by holding both ends of a barrel bearing with holders set at the front and back of the moving direction of a positioning device and putting a guide rod through the barrel bearing. CONSTITUTION:A barrel bearing 5 is bonded to holes 2a of a shift base 1 by an adhesive, etc. at its outer circumferential part. At the same time, the bearing 5 uses a sintered oilless bearing. Thus it is possible to secure the precise guide restriction between a guide rod 4 and the bearing 5, i.e., the rod 4 and the base 1 regardless of the rigidity and the processing accuracy of the base 1 at the peripheries of holes 2b. Furthermore a simple structure containing just upper and lower dies suffices with a metallic mold of the base 1 since a round shape can be changed to a U-shape for the holes 2b.
