Title: Remote controller
Inventor: HIGASHIHARA MORIO
IPC: H04Q9/00
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent control signals from simultaneously being transmitted, when plural remote control transmitters are used. SOLUTION: A CPU 12 sets the time from which a receiving means 15 receives a reference signal h1, until a transmitting means 13 sends a control signal d1, based on the selection of a changeover switch 14. Thereby, plural remote control transmitters 10 can transmit a control signal at different timings, because plural transmitters 10 make the switch 14 perform separately different selection. Therefore, when plural transmitters 10 are used, control signals are prevented from being transmitted simultaneously.

Title: Stripping agent used for water-soluble photoresist and its use method
Inventor: MIYAZAWA SHIYOUZOU
IPC: C23F1/00
Filed: 1980-11-26
Abstract: PURPOSE:To strip a water-soluble photoresist, by using hexamethyl-phosphoramide. CONSTITUTION:A photoresist plate with an image formed is immersed in an aqueous solution containing hexamethylphosphoramide represented by the chemical formula (I) and further, when needed, periodate and a surfactant, and treated in 40-90 deg.C temperature range. Hexamethylphosphoramide is contained in 1-10wt% range. The action is smaller below this range, but it is not so much raised above this range. The periodate and the surfactant enhance wettability and diffusibility, shorten the treatment time, and reduce an amount of hexamethylphosphoramide to be used. The photoresist may be removed by coating this solution and rubbing it with a brush, but the immersion method is much easier. This solution does not corrode a metal, and its operation is out of danger.

Title: Bone coupling material
Inventor: INOUE KIYOSHI
IPC: A61L27/00
Filed: 1990-06-26
Abstract: PURPOSE:To obtain excellent durability with a strengthened bonding to a bone by applying a dull working (fine irregularity producing working) to the surface of a metal material. CONSTITUTION:In this bone coupling material, a dull working is applied to the surface of a metal material with a working surface roughness exceeding 20muRmax by electric discharge machining or laser working to an extent to about 10muRmax-50Rmax in surface roughness. For example, titanium (Ti) mate rial with a working surface roughness of 30muRmax undergoes an electric dis charge machining in pure water (with specific resistance of 10<6>OMEGAcm) using a wire electrode made of Br (brass). In this process, four types of dull working is accomplished with the surface roughness of 6muRmax, 11muRmax, 23muRmax and 26muRmax by varying a current peak value Ip and a pulse width gammaon of a voltage pulse for machining centering around Ip=180A and gammaon=1.8muSec. This dull working multiplies the surface area of a bone coupling material 15-25 times. When the surface of the bone coupling material is analyzed by ESCA (X-ray electronic spectroscopy), microscopic adhesion of Zn and Cu is confirmed.

Abstract: PURPOSE:To prevent any breakage of the electrolyte tube of a sodium-sulfur battery which might occur during the initial temperature increase of the battery by placing a positive body, which consists of sectoral sections each having slits on its inner surface, outside an electrolyte tube packed with a negative active material. CONSTITUTION:After molten sodium 2 used as the negative active material is packed inside an electrolyte tube 1, a positive body 12 which is made of carbon fiber impregnated with molten sulfur and packed in a case 5 is placed outside the electrolyte tube 1 to produce a sodium-sulfur battery.
