Title: Toggle joint valve equipment
Inventor: FUJITA TOMOHIRO
IPC: B60T15/36
Filed: 1977-12-20
Abstract: PURPOSE: To provide high pressure service by installing a pair of differential pistons in tandem in a cylinder and assembling an open check valve and a piston connecting element.  
     CONSTITUTION: The primary and secondary differential pistons 3, 21 are in tandem installed in a staged cylinder 2, 2' and 20, 20' of a cylinder body 1. The movement of the pistons makes a pressure value of outgoing oil larger than a pressure value of incoming oil in each of the primary and secondary hydraulic system. Open check valves 13, 31 and a connecting rod 927 are assembled in the cylinder. When the pressure of oil supplied into an oil chamber 4 rises over a specific value, the primary differential piston 3 moves to the ring and after a flow course 6 is cut off, the piston operates as a different-diameter piston. Both oil pressure of the incoming oil chamber 22 and the outgoing oil chamber 5 are combined to affect the large- diameter edge of the secondary differential piston 21, resulting that the output oil pressure is duplicated at a large ratio higher than the output oil pressure from the primary hydraulic system.

Filed: 1984-07-25
Abstract: PURPOSE:To prevent leakage by a parasitic transistor, and to manufacture a semiconductor device with high yield by forming a dummy gate pattern as a gate electrode pattern not used as a wiring onto an isolation region on the formation of a gate electrode. CONSTITUTION:A thick oxide film 2 and a gate oxide film 3 are shaped onto a semiconductor substrate 1, and a gate electrode layer is deposited onto the whole surface. The gate electrode layer is patterned in order to form gate electrodes 4a, 4b onto an isolation region (a) and an element region (b), and a dummy gate pattern 8 is shaped. A space (l) between the dummy gate pattern 8 and the gate electrode 4a on the isolation region (a) is brought to approximately twice as long as the width (m) of a side wall 5. Ions are implanted in order to shape a low-concentration diffusion layer 7, and the diffusion layer 7 is deposited onto the whole surface of the PSG substrate 1 as a forming layer for the side wall 5. High-concentration diffusion layers 6 are formed through anisotropic etching using RIE employing a furon group gas and ion implantation while using the side wall 5 and the gate electrode 4b as masks.

Title: Winding machine for magnetic head
Inventor: OTANI MICHIO
IPC: G11B5/17
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To enable windings in high yield by making inner walls of the winding window of a magnetic head chip become roughly parallel with a direction along which a wire for winding passes, to enable the wire to operate in the winding window with good margins. SOLUTION: A magnetic chip 1 is placed by being inclined at roughly the same angle as a gap azimuth angle θ in order to make the inner walls of a winding window 3 roughly parallel with the direction along which the wire for winding passes in the winding window 3 of the magnetic head chip. Consequently, the effective winding window width for the winding of the magnetic head chip can effectively use the width equivalent to roughly the same as the winding window width in a tape sliding direction regardless of the azimuth angle. For example, the wire of 0.03ϕ is wounded by inclining a magnetic head chip 1 which is the audio head of the VHS and whose azimyth angle is 30 degrees and in which the winding window width in the tape sliding direction is 300 μm at 30 degrees.  Then, the effective winding window width becomes 300 μm and the windings of 30 turns are performed with good margins and also the winding yield is 100%.

Title: Communication control system for contactless ic card
Inventor: MOROSAWA KENJI
IPC: G06K17/00
Filed: 1992-06-12
Abstract: PURPOSE:To suppress the useless consumption of electric power by providing a communication controller which receives the output of a human approach sensor and starts the communication with the contactless IC card held by a human. CONSTITUTION:A contactless IC card 4 held by a human is provided together with a human sensor 10 which detects the approach of a human, and a communication controller 3 which starts the communication with the card 4 after reception of the output of the sensor 10. The controller 3 usually discontinues the transmission of the microwaves. The sensor 10 detects the approach of a human and informs the controller 3 of this fact. The controller 3 transmits the microwaves only when the signal is received from the sensor 10 and then can read the data out of the card 4. Therefore no microwave is transmitted as long as the approach of a human is not detected. Thus the useless consumption of electric power can be suppressed.

The coincidence signal 6a is inputted to a gate circuit 7, controlling the passing of a drive signal 8a from a drive circuit 8. In this way, from the gate circuit 7 is outputted the drive signal 8a of time correspondingly corrected to a coil diameter D of the coil material 1, thus the coil material 1 is stopped at the prescribed position.

Abstract: PURPOSE:To decrease the number of parts and to facilitate assembling and fabrication by mounting a piece of piezoelectric element and a weight provided integrally and continuously with an oscillating part which resonates at the knocking frequencies of internal combustion engines superposedly to the cover of a  shell. CONSTITUTION:A sensor for knocking is provided with a mounting screw hole in its cover 10, and is mounted with a piezoelectric element 1 and a weight 3 provided integrally and continuously with an oscillating part 2 which resonates at the knocking frequencies of internal combustion engines superposedly by means of a mounting screw 5 on the inner side of the cover 10 in such a way that the element 1 comes to the cover side. Electrode plates 6, 7 which draw out the output voltage generated in the element 1 are stuck and connected directly to terminals 13', 14' penetrating through the cover 10 via sleeves 11, 12, respectively. Thus the oscillations transmitting from the internal combustion engine to the shell are transmitted directly to the cover 10, by which knocking is sensed in the same way as in the prior art, the number of parts is reduced and assembling and fabrication are made easy.

At the lower end of the grids 10, 11, there is provided a trough 4, so that balls are introduced into a ball capturing chamber 8 by the guide of the grids and superfluous water is discharged from a outlet port 7 of the chamber 8. Therefore, a proper amount of water and balls are introduced again into cooling water from a ball extracting port 6 and used for cleaning the inside of heat transfer tubes of the heat exchanger. Thus, since water and balls are discharged slantly downwards by the guide of the trough 4 while restricting the water flow in the form of a funnel along the water flow by means of the grids 2, 3, balls can be recovered in a tank 1 having a small length along the water flow. At the same time, it is enabled to reduce the number of component parts of the grid device and to enhance reliability of the same.
