IPC: H03H15/00
Filed: 1979-12-13
Abstract: PURPOSE:To eliminate code-to-code interference by laying emphasis by detecting the correlation of impulse response at an adequate frequency in the base band. CONSTITUTION:A signal having the output level flattened by variable gain circuit 2 is delayed by delay circuits 61-6N by times tau1-tauN.

Patent JP-H0721783-A (JP)
Title: Optical information recorder
Inventor: NAGANO KATSUTO
IPC: G11C11/42
Filed: 1993-06-30
Abstract: PURPOSE:To record and read out information while maintaining the change in the reflectivity of light passing a gate insulating film by using a ferroelectric film in the optical information recorder and preserving the polarization induced in the ferroelectric film. CONSTITUTION:The ferroelectric film 5 is polarized and electrons are excited in the front surface of a silicon substrate 1, by which the light reflectivity on the surface of the substrate 1 is changed when a positive voltage is impressed to a gate electrode 3. Since the film 5 is used in this optical information recorder, the polarization induced in the film 5 is preserved and the change in the reflectivity on the front surface of the substrate 1 of the light passing the film 5 or the gate insulating film 2 is maintained and the optical information is recorded on the semiconductor surface. When the light L is made incident, the incident light is reflected between the substrate 1 and the electrode 3, is propagated in the SiO2 layer and is emitted from the side opposite to the incident position. As a result, the information recorded on the semiconductor surface is directly read out by using the light.

Title: Removal of spontaneous oxide film on surface of semiconductor substrate
Inventor: SUGINO SHIGEJI
IPC: C23F4/00
Filed: 1988-06-28
Abstract: PURPOSE:To remove a spontaneous oxide film on the surface of a substrate without damaging a semiconductor and reducing the characteristic of the semiconductor by performing etching by exposing the semiconductor substrate to a decompressed atmosphere of carbon-momoxide-gas-added chlorine gas for a certain time. CONSTITUTION:A silicon substrate 4 is placed on a mount 3 installed in the chamber 2 of a reaction apparatus 1 and the mount 3 is heated whilst the pressure in the chamber 2 is reduced. Cl2 gas and CO gas are introduced into the chamber 2 and ultraviolet rays are applied to the substrate 4 from light sources 6 vertically. This state is maintained for a certain time. This converts Cl2 into radical Cl with ultraviolet rays and separates O of the SiO2 film on the substrate 4 to turn it into radical O. CO gas in the chamber 2 captures radical O separated from the surface of the substrate 4 by Cl to form CO2. Si of the substrate 4 reacts to Cl to become SiCl4 and vaporized to perform etching. This enables removing a spontaneous oxide film on the surface of the substrate without damaging a semiconductor and reducing the characteristic of the semiconductor.

A tapered portion 22 in the middle, the diameter of which becomes smaller downward, is bent outward in a key pushing operation. With this constitution, an initial pushing pressure becomes slightly higher so that sensitivity in the key pushing operation becomes excellent despite of a short pushing stroke of the key, thereby obtaining a keyboard excellent in return responsiveness.

IPC: H01L21/265
Filed: 1991-06-05
Abstract: PURPOSE:To prevent attaching of particles to a target by furnishing a mesh-form electrode in the near surrounding of the target, and thereby generating a negative potential. CONSTITUTION:A mesh-form electrode 20 electrically insulated from a Faraday case 8 as near surrounding is furnished in the near surrounding of a target 4, i.e., on the inside of the bottom plate 8a of the Faraday case 8. A negative voltage from a DC power supply 22 is impressed on this electrode 20. Thereby the electrode 20 is given a negative potential, and secondary electrons released from the target 4 etc., are not likely to reach particles 16 on the bottom of the case 8, and therefore, the particles 16 will not easily be charged negatively. Eventual charging negative is repelled by the negative potential of the electrode 20, so that the particles 16 are checked from going toward the target 4 and precluded from attaching to it.

Title: Contrast medium-containing tube
Inventor: GOSHIKI KEIGO
IPC: A61M25/00
Filed: 1989-06-23
Abstract: PURPOSE:To obtain the contrast medium-contg. tube which is free from discoloration by coating the surface of X-ray contrast medium particles with an anhydrous metal oxide film to prohibit the contact of the decomposition product of high reactivity generated from the fluoroplastic resin at the time of tube formation and the X-ray contrast medium particles. CONSTITUTION:The anhydrous metal oxide film is obtd. by adding the X-ray contrast medium particles of bismuth oxide, etc., to an aq. sol. of, for example, a metal sulphate, metal chloride, metal oxychloride, etc., and neutralizing the soln. by caustic soda, etc., then drying and igniting the same. The water soluble metal sulphate, etc., deposit as the metal oxide hydrated by hydrolysis on the surface of the X-ray contrast medium particles. The hydrated metal oxide is dehydrated by the heating to make the anhydrous metal oxide. The anhydrous metal oxide film acts as a shielding layer to the decomposition product of high reactivity generated from the molten fluoroplastic and effectively protects the contact thereof with the X-ray contrast medium particles when the X-ray contrast medium particles catered with the anhydrous metal oxide film are incorporated into a tube wall consisting of the fluoroplastic. The discoloration of the tube after molding is, therefore, not admitted.

IPC: H02J7/02
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To charge a battery optimally and shorten the charging time and improve the properties on the quantity of charging and the charging time, by controlling the constant voltage charging of a battery by the voltage drop value at the time of switching from constant-current charging to constant-voltage charge, and the value of the current which was flowing at that time. SOLUTION: CPU 5 is built in a charger 4, and the charging method is decided by the battery voltage detected by a battery voltage detecting means and the battery current detected by a battery current detecting means 3. CPU5 remembers the relation among the voltage drop value at switching from constant current charging to constant voltage charging, the constant voltage charging time, and the charging finish current. Then, it is possible to charge the battery optimally by deciding the constant voltage charging time by the voltage drop value at switching from constant current charging to constant voltage charging and the value of the current which was flowing at that time. Hereby, the charging time can be shortened and the properties on the quantity of charging and the charging time can be improved.
