Title: Water bed
Inventor: NAGATAKE HIROSHI
IPC: A47C17/02
Filed: 1991-08-28
Abstract: PURPOSE:To offer a light-weight water bed on which a user's body is prevented from coming in contact with the bottom of the bed and water wavers a little when the user moves in the bed. CONSTITUTION:Two or more different water depths are applied to a water bed. As a means to vary the water depth, for example, an air bag 2 having an uneven surface is laid under a water bag 1 filled with water to make the bottom face 1a of the water bag 1 uneven, so that the distance from the upper face 1b to the bottom face 1a varies for every place. When the water depths are deeper at places which bear larger portion of a body weight and dent deeper, and shallower at the places which bear smaller portion of the body weight and dent a little, the body is prevented from coming in contact with the bottom throughout the water bed, wavering of water is hard to occur and the weight of the bed is made lighter.

Inventor: KUWAZUKA TOSHIAKI
IPC: C07C323/25
Filed: 1991-09-24
Abstract: PURPOSE:To obtain granular cysteamine hydrochloride by adapting a distillation- salt formation-concentration process instead of a crystallization-filtration of centrifugation-drying process, producing the product in a melted state, cooling the melt and subsequently solidifying the cooled product. CONSTITUTION:A reaction product e.g. obtained by reacting 2-chloroethylamine hydrochloride with 2-mercaptothiazoline is distilled to obtain a cysteamine solution, which is neutralized with concentrated hydrochloric acid to produce a cysteamine hydrochloride solution. The cysteine hydroxhloride solution is concentrated under vacuum and heating to distill out water, and the crysteamine hydrochloride is held preferably in a melted state at approximately 70-100 deg.C without being taken out as crystals, cooled, coagulated and granulated. By the method, the cysteamine hydrochloride obtained from various raw materials can be granulated without being handled as the powder. The processes ranging from the synthesis of the crysteamine or cysteamine hydrochloride to the granulation of the cysteamine hydrochloride can be simplified and the cost of installations can be reduced.

Title: Device for testing pulverizing property of coke for blast furnace
Inventor: IWANAGA YUUJI
IPC: C10B57/00
Filed: 1983-12-23
Abstract: PURPOSE:To improve the productivity of a blast furnace by using a testing device which can evaluate and test the characteristic of coke for a blast furnace under the conditions meeting the actual furnace. CONSTITUTION:The gas having the compsn. resembling to the top gas of a blast furnace is manufactured by a mixer 5 and is introduced into a reaction tube 2 from the lower part. The pipe 2 is vertically oscillated by an oscillator 4. The gas contg. CO2 or H2O reacts with coke and changes to the gas carrying CO or H2. The coke disappears gradually by reaction from the surface of the particles but when a decrease in the strength arises, a powdering phenomenon arises in the coke layer by the oscillation. The generated powder coke is thus entrained by the gas and is discharged to the outside of the system through an output pipe 7. Such coke is captured by a cyclone 12 and the weight is measured and integrated by a balance 13. The powder coke is cooled by a water cooling cylinder 16 during this time. The discharged gas is discharged through a gas combustion cylinder 17 to the atmosphere. The behavior of the coke in the blast furnace is thus simulated. The productivity of the blast furnace is improved by using such testing device.

Title: System reset circuit of microprocessor
Inventor: HASHIKAWA KENZO
IPC: G06F11/00
Filed: 1984-11-19
Abstract: PURPOSE:To reset efficiently a microprocessor when a system power supply is applied and the system runaway occurs by using a gate circuit which synthesizes the output of an FF and the output of an oscillation circuit to produce a system reset signal in a power supply application mode and a program runaway mode. CONSTITUTION:When an oscillation circuit 11 starts its working when a power supply is applied, a rise edge detecting circuit 12 detects the rise of an oscillation output signal B and resets an FF15 with the output C. The output F is kept at 'L' while the FF15 is reset. When the signal B is produced during this period, the reset signal G of a gate G4 has a rise. The output of the G4 is kept at a fixed level as long as a program is executed normally. Here the program has a runaway and no edge detection output E is produced any more. Thus the FF15 is kept reset. While the output G repeats 'H' and 'L' alternately in response to the oscillation output B. Here the runaway is reset by making use of the rise of the output G. This rise is produced continuously until the system is reset to its normal state.
