Title: Idle rate of revolution controller
Inventor: TATENO HIDENORI
IPC: F02D33/00
Filed: 1980-07-25
Abstract: PURPOSE: To easily determine the direction of revolution of the stepping motor for driving the said control means at the initial control time, such as start time, and reduce the time up to the control start by relatively detecting the current position for the reference position of an intake flow control means.  
     CONSTITUTION: When the valve body 20a of an air flow control valve 20 is set to the low opening at which the valve is located right from the reference position, an electrode 32 is in contact with an electrode 36 and a spring 34 is slightly compressed. For this purpose, a stepping motor 34 is revolved counterclockwise through an electronic control circuit 26 during the engine start and the valve body 20a is moved left. Consequently, since the valve body 20a passes through the reference position in a short period of time, the control circuit 26 can quickly and accurately detect the current position of the valve body 20a. At the idling time, i.e. when a throttle valve 14 is fully closed, the intake which flows in an intake manifold 16 through a bypass passage 18 is controlled by opening the valve of this valve body 20a and the number of idle revolutions is maintained in a specified value.

Title: Ice heat storage unit
Inventor: ITO KATSUNORI
IPC: F24F5/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To provide an ice heat storage unit in which ice can be distributed uniformly in an ice heat storage tank through a simple structure. SOLUTION: A float 41 is moored on the bottom face or the opposite side faces of a heat storage tank 8 by means of a mooring member 43, e.g. a stainless steel wire and disposed at a part abutting against the surface of supercooled water 5. When supercooled water 5 flows down from a supercooler 6 into the heat storage tank 8, it collides against the float 41 and the float 41 is oscillated in an arbitrary direction with the impact. Since the oscillating direction is not fixed, supercooled state is released through collision against the float 41 and ices 7 thus produced are distributed uniformly in the heat storage tank 8.

Abstract: PURPOSE:To improve the coverage of a wiring metal film which is formed in an after process by a method wherein a hole which connects wirings with each other or a wiring with a board is formed into such a shape that it has two or more constricted parts. CONSTITUTION:An insulating film and a resist pattern are formed on a board 2, which is dipped into a wet etching solution to form a hemispheric hole. Then, the board 2 is subjected to a dry etching to form a hole of a first stage wet and dry etching. Hereafter, the same process is repeated once or more to make the hole become gradually larger toward its upper part in diameter, so that hole has a gentle slope which extends from its top to bottom. Thereafter, the resist is removed to form a cone-shaped contact hole which has two or more constricted parts.

Air is sent into from the bottom of the cooler 2 to countercurrently contact the sintered ore 3 thereby to obtain high- temperature air of 450W650° from the top of the cooler 2. The high-temperature air is guided into the sintering machine 7 and is used as the air for the sintering machine. The high-temperatured air is not reduced in oxygen concentration, accordingly, it accelerates sintering action and enhances the yield of sintering, thereby enabling to decrease the consumption of coke ratio because the insufficient heat is supplemented satisfactorily.

Title: Video tape recorder for high-speed dubbing
Inventor: YAMASHITA KOUJI
IPC: G11B5/86
Filed: 1984-05-23
Abstract: PURPOSE:To permit high-speed dubbing by maintaining the same relative speed between a head and tape and the tape pattern as those in the conventional method and increasing the tape speed according to the increase in the number of the heads. CONSTITUTION:The lead angle of a drum is made smaller than in the conventional practice when the tape speed is increased in the stage of realizing high-speed dubbing. The consequent change in the scanning length of the video head can be prevented simply by increasing the diameter of the drum to increase the video track length K in the tape feed direction so that the head scans across the video width W. The integer multiplication and the high-speed dubbing tape recorder at such magnification can be realized simply by attaching plural pairs of the heads equiv. to said integer multiplication to the rotary drum and constituting the heads in such a way that the same azimuth part of the video tracks is traced or recorded by each head at the number of the heads of integer times the one rotation of the drum. Each pair of the heads are installed at the height differently with respect to the horizontal reference plane of the rotary drum in this case.

Abstract: PROBLEM TO BE SOLVED: To enable a bank clerk to take a passbook out of a passbook collection mechanism part just by opening the front door of a cash dispenser and accordingly to improve the working efficiency and the labor saving for the bank jobs by placing the passbook collection mechanism part at a position above a passbook feed path an also near a passbook discharge part with the linkage secured to the feed path. SOLUTION: If a customer has omitted to take his passbook 9 that is discharged to a passbook slot, the rollers 2 to 7 are revolved toward a print head 8 and then stopped when a detector 44 detects the lower edge part of the passbook 9. Then a DC solenoid is driven to switch an inserter 31 toward a passbook collection part 38. Thus, a passbook feed path 23 is linked to the part 38. The passbook 9 that is stopped via the detector 44 passes the inserter 31 through the path 23 and is led to the part 38 when the CD solenoid is driven to drive again the rollers 2 to 7 and also the rollers 34 and 35 of the part 38. Thus, a bank clerk can easily take out the passbook 9.
