Title: Semiconductor device
Inventor: SUZUKI AKIRA
IPC: H01L23/29
Filed: 1980-02-20
Abstract: PURPOSE:To prevent a wiring from corrosion, by composing a joint pad of a metal such as Mo, etc. which has a higher corrosion resistance than a wiring layer of Al, etc., and further by providing a protective membrane with a window on the pad. CONSTITUTION:An Al wiring layer 20 is provided on an Si substrate in such a manner that its width becomes broader than the extended section at a section 20a where it contacts an Mo joint pad 14, and by doing so, wiring resistance is reduced. And then, an entire surface is covered with an Si3N4 membrane, and an opening 21a is provided on a part of the pad 14. Ni and Sn, etc. are plated on the opening 21a to provide a better joining performance with an Au wire. In this mechanism, because of the facts that the pad 14 is made of Mo whose corrosion resistance is higher than Al and that surface of the Al wire is covered with the protective membrane Al can be prevented from corrosion improving reliability of a device.

Title: Peptide
Inventor: MIAKE FUMIO
IPC: C07K14/00
Filed: 1984-02-02
Abstract: NEW MATERIAL:A compound (salt) expressed by formulas I -VII (R<4> is H or protecting group of mercapto). USE:An antigen for analyzing hepatitis B viruses and antigen for hepatitis B vaccines. PREPARATION:For example, serine having amino group protected with tert- butoxycarbonyl group is linked to a chloromethylated styrene-divinylbenzene copolymer resin as a carrier to give N-tert-butoxycarbonyl-O-benzylserine resin. The amino group of the resultant resin is then eliminated, and amino acids having protected amino groups are condensed with the resin according to the amino acid sequence of the aimed peptide in the presence of a condensing agent. The operation to eliminate protecting groups is repeated successively to afford a peptide resin, which is then treated with hydrogen fluoride in the presence of a solvent to separate the peptide from the carrier and give the aimed peptide expressed by formulas I -VII.

Title: Idle rotational speed control device
Inventor: MIZUNO KAZUYOSHI
IPC: F02D41/16
Filed: 1984-02-03
Abstract: PURPOSE:To nullify a bypass function other than upon idle operation to obtain a satisfactory normal operation, by positioning the downstream end of a bypass passage upstream of a throttle valve at its full close position but upstream of the same valve at its predetermined open-degree position. CONSTITUTION:During a throttle valve 20 is at its full close position, that is upon idle operation, intake vacuum is effected at the downstream end 31 of an intake-air passage 10 so that air flows through the intake-air passage 10 in the direction of the arrow, and the flow rate of this air is controlled in association with an opening degree determined between a valve body 41 and a valve seat 42 in an air valve 40 to control the rotational speed of an engine. When the opening degree of the throttle valve becomes larger than a predetermined value so that the vacuum at the downstream end 31 approaches to the atmospheric pressure, no air flows in a bypass passage 30, and therefore, the rotational speed of the engine cannot be controlled any more by the opening degree between the valve body 41 and the valve seat 42 but is controlled by the opening degree of the throttle valve 20 alone so that discrepancy due to unexpected control operation may be eliminated.

Abstract: PURPOSE:To obtain disk structure which has a long recording life and has the strength higher than the strength of air gap structure by forming a recording film consisting of tellurium (Te), titanium (Ti), silver (Ag), and selenium (Se) and having a specific compsn. on a substrate. CONSTITUTION:The recording film 2 on the substrate 1 consists of [Te(100-x-y-z).Ti(x).Ag(Y).Se(z)] and since mol.% of x-z is 0<x<=20, 0<=y<=3, 0<z<=50, the heat transition temp. to generate a phase change can be adjusted to about 120-170 deg.C and a change of reflectivity to about 10%. Since the recording film 2 generates a change of the optical characteristics by the phase change, the need for forming the optical recording medium into the air gap structure like with the conventional medium formed with pits is eliminated and direct adhesion of protective layers 3, 4 onto the recording film 2 is possible. The optical recording medium having the excellent strength is thereby obtd.

IPC: A47G25/36
Filed: 1995-02-08
Abstract: PURPOSE: To extend the life and improve the machining productivity by forming at least the hanger main body of a shape stable machining hanger with a polyphenylene sulfide resin. CONSTITUTION: The suspension section 2 of a hanger 1 and the clothes hook section 3 of a hanger main body are integrally molded with a polyphenylene sulfide resin. The polyphenylene sulfide resin is preferably heat-cured for molding and has a cross-linking structure in molecules. The thermal deformation temperature is preferably set to 130 deg.C or above. When the thermal deformation temperature of the resin is low, the shape of the hanger 1 cannot be maintained via the heat treatment by steam for shape stable machining, and it is undesirable. A chemical such as formalin is used for the shape stable machining of a fiber product, chemical resistance is required for the hanger 1 itself. The polyphenylene sulfide resin primarily has chemical resistance, and any chemical used for the processing agent of the fiber product can be used for manufacturing this hanger 1.

Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To reduce a read time without increasing the storage capacity of a reproduction information storage area by compressingly storing reproduction control information, storing compressed information and recording positions being on a recording medium while relating them and restoring the compressed information. SOLUTION: Before a microprocessor executes a readout to a recording medium, it retrieves a management table in which reproduction control information being in a compressed information storage area and read-out positions of the recording medium are related to judge the presence or absence of the reproduction control information. When the reproduction control information are present, it reads out compressed information from a compressed information storage area and expands them to transfer them to a readout information storage area. When the reproduction control information are not present, it instructs the reading of the recording medium to a recording medium reading device. The device reads out reproduction control information from the medium to transfer them to the readout information storage area.  Only information needed for reproductions from the reproduction control information area stored in the reproduction control information storage area.

Abstract: PURPOSE:To prevent a large amount of liquid refrigerant and lubricants from remaining in a suction pipeline and hence protect the capacity of an air conditioner from being degraded by carrying out forced defrosting operation irrespective of the presence of frost deposited on an outdoor heat exchanger during heating operation. CONSTITUTION:When starting the control of an air conditioner, the heating operation of an indoor unit is started at first and a first timer is turned on so as to decide if the setting time (for example, 50 minutes) of the first timer has lapsed.
