Title: Washing device
Inventor: WADA TATSUYA
IPC: H05K3/26
Filed: 1990-01-11
Abstract: PURPOSE:To prevent the formation of explosive gases in a washing tank and to improve a safety by providing an inert gas supplying means which introduces an inert gas from the outside into the liquid in the washing tank and diffuses the gas at the time of work washing. CONSTITUTION:The inert gas rises in the form of bubbles in the liquid of an org. solvent 2, emerges from the liquid surface and diffuses into the upper space 1a in the washing tank 1 when the inert gas introduced from the bottom of the tank 1 from the outside is diffused by a gas diffusion pipe 4 at the time of washing of the work 3. The atmosphere in the upper space 1a in the tank 1 is, therefore, substd. eventually with the inert gas. Since the air hardly exists in the space 1a in the tank 1 even if combustible vapor is generated by the evaporation of the org. solvent 2 in this state, there is no possibility of forming the explosive gases. There is substantially no danger of inflaming and burning of the org. solvent 2 and the vapor thereof even if an inflammation source approaches the same. The safety is thus assured.

Title: Awakening maintainer and recording medium for maintaining awakening
Inventor: ISHIDA KENJI
IPC: H04S7/00
Filed: 1995-01-13
Abstract: PURPOSE: To exert an awakening maintenance effect without a sense of any incompatibility by presenting an audio frequency bandwidth sound countinuously, and simultaneously more than the specified value of this frequency bandwidth sound intermittently at the specified interval, or increasing or decreasing the sound pressure in succession. CONSTITUTION: A sound regenerated by a sound regenerator 12 is divided into two systems, and it is passed through a high pressure frequency 14 extracting an ultrasonic wave area and a low pressure frequency 16 extracting an audible sound area respectively. The ultrasonic wave area sound passed through the HPF 14 is inputted into an amplifier 22 intermittently by a switch 18. In addition, the audible area sound passed through the LPF 16 is inputted into the amplifier 22 continuously. Then, in this amplifier 22, the ultrasonic area sound to be intermittently inputted and the audible area sound to be continuously inputted are amplified respectively, then these two areal sounds are compounded and outputted to a speaker 24, presenting it to a driver.  In this connection, when the ultrasonic wave areal sound is intermittently presented, biological activities in the brain proper are unconsciously alterable, so an awakening maintenance effect is thus obtainable.

Title: Magnetic recording medium
Inventor: AZUMA HIROSHI
IPC: C10N40/18
Filed: 1986-01-10
Abstract: PURPOSE:To improve the wear resistance of a magnetic layer and to obtain the titled magnetic recording medium having excellent durability by using a specified polycyclic ketonic compd. as the lubricant to be incorporated into the magnetic layer. CONSTITUTION:Bicyclic ketonic compds. shown by formulas (1)-(3) are most typically used as the polycyclic ketonic compd. Each carbon ring is preferably composed of 3-8 carbon atoms. Although the carbons are mostly single-bonded, a part of carbons can be double-bonded. Besides, the carbon atoms constituting the carbon ring may have a substituent such as an alkyl, a nitro group, a sulfonic group, a phosphoric group, a halogen, hydroxyl, and carboxyl. Since such a polycyclic ketonic compd. has excellent lubricity and compatibility with the binder resin, excessive oozing out of the compd. onto the surface of the magnetic layer when added into the magnetic layer is controlled in sliding contact with a magnetic head, hence the lubricity can be maintained for a long period, and the wear resistance of the magnetic layer is remarkably improved.
