Title: Head rest
Inventor: ISHIKAWA HIYOSHI
IPC: B60N2/48
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To improve the head's safe holding at curving drive and an acoustic- isolating effect for resting time by setting a pair of turning pads both at the right and left sides of the central pad holding the head so that they can be turned. SOLUTION: The turning pads H2 are provided with a No.2 insert composed of a U-shaped rotary core 20 and a pad material P2 into which the No.2 insert is buried. The rotary core 20 is made of a metal pipe, for instance, to which a connecting projection 21 composed of a plate spring at each of the top and bottom inside edges is firmly connected. This connecting projection 21 is connected to a connecting recess 17, by which the rotary core 20 can be fixed to a connecting member 12. The connecting member 12 is set so as to enable it to turn orderly around a base shaft 13 by forming a cylinder 14 so that, for instance, a metal plate can then be folded back along the base shaft, so that a small projection can be made inward in the cylinder 14 to generate a friction force, and so forth.  When a driver and others take a nap and the like, forward rotating the turning pad H2 against a central pad H1 to make the second state, can improve the acoustic-isolating effect and pursue the comfortableness.

Title: Semiconductor device provided with special test function circuit
Inventor: AKAOGI TAKAO
IPC: H01L27/04
Filed: 1989-03-10
Abstract: PURPOSE:To prevent the malfunction of a special test function due to noise by operating the special test function only at the time of simultaneous application of a high voltage to plural external terminals. CONSTITUTION:Only when a high voltage is simultaneously applied to plural external terminals 11 and 12, an output VH0 of a logic circuit 41 goes to the high level, and the output of a decoder 51 which decodes the signal applied to terminals 13 to 1n is taken into pertinent one of latches 61 to 6m.

Title: Switching controlled type power source circuit
Inventor: SHIYOUNO MASAHIRO
IPC: H02M3/338
Filed: 1982-04-07
Abstract: PURPOSE:To enable to use a control transistor which has low reverse withstand voltage by reducing a reverse bias applied between the base and the emitter of the transistor during the OFF period of a switching transistor. CONSTITUTION:Since both control transistors TR2, TR3 are OFF during the OFF period of a switching transistor TR4, the reverse voltage of a feedback coil N is not applied to a point (M), and the point (M) accordingly becomes a voltage which is lower in the amount of a voltage between both terminals of a condenser C5 to a line L2. Therefore, the reverse bias voltage applied between the base and the emitter of the transistor TR2 in this state becomes low. In this manner, an inexpensive transistor which has relatively small reverse withstand voltage can be used for the control transistor.

Title: Manufacture of semiconductor device
Inventor: ISOZAKI TSUNEAKI
IPC: H01L21/3205
Filed: 1984-03-27
Abstract: PURPOSE:To eliminate an abrupt difference in steps in the edge of a pattern for preventing a wire from being disconnected there, by applying two layers of P type photoresists having different sensitivities, exposing and developing them to form patterns of the two layers of the photoresists, and performing anisotropic etching and isotropic etching successively. CONSTITUTION:A silicon dioxide film 3 is formed on the surface of a semiconductor substrate 1, which is applied with a P type photoresist 5 having a low sensitivity. Light is applied vertically to the region where a contact hole is to be formed, whereby the photoresist 4 having a higher sensitivity is light sensitized in a larger area. As a result, the photoresist 5 is protruded inside the photoresist 4. The silicon dioxide film 3 is then etched with an etching apparatus utilizing directional plasma, whereby a contact hole having an abrupt level difference is formed. This silicon dioxide film 3 is further wet etched, so that the edge of the contact hole is shaped smoothly. In such a manner, an aluminium wire pattern 6 can be formed smoothly even on the periphery of the contact hole and therefore disconnection of the wire can be effectively prevented.

Title: Magneto-resistance effect type head
Inventor: TODA JUNZO
IPC: G11B5/39
Filed: 1989-03-14
Abstract: PURPOSE:To prevent the degradation of the reproduction efficiency arising from the trend toward narrower tracks and the generation of Barkhausen noises by forming a shunt conductor of a soft magnetic material having a small magneto-resistance effect and laminating a magneto-resistance effect element having a prescribed track width on the shunt conductor so as to come into contact therewith. CONSTITUTION:The shunt conductor 2 consists of the soft magnetic material having the small magneto-resistance effect and the magneto-resistance effect element (MR element) 1 having the prescribed track width is laminated on the shunt conductor 2 so as to come into contact therewith. Since the MR element 1 is lined with the soft magnetic shunt conductor 2 in such a manner, the diamagnetic field in the track width direction of the MR element 1 is decreased and the generation of a reflux magnetic domain is suppressed. The axis of easy magnetization is imparted in the track width direction even in the narrow track width in this way and the degradation in the reproduction efficiency is prevented. Since the unnecessary magnetic domain does not exist, the generation of the Barkhausen noise is prevented as well.
