Title: Ice-making apparatus
Inventor: KAWAHARA TOSHIYUKI
IPC: F25C1/18
Filed: 1988-08-04
Abstract: PURPOSE:To enable transparent ice to be produced in a short period of time by using an ice-making vessel made of a superconductive material whose critical temperature is higher than the freezing point of water and making ice by cooling said ice-making vessel in a freezing chamber wherein a cooler and a permanent magnet are equipped. CONSTITUTION:As an ice-making vessel 1 is in a normal conductive state when a temperature in a freezing chamber is high and the ice-making vessel 1 is held at a temperature higher than a critical temperature, magnetic lines of force 6 generated by a permanent magnet 2 pass through the ice-making vessel 1. Accordingly, the ice-making vessel 1 is cooled in a state of being in contact with an inner wall 4, and the temperature of the water 5 in the ice-making vessel 1 is rapidly lowered. When a temperature decreases to a level below the critical temperature of a superconductive material constituting the ice-making vessel 1, the ice-making vessel 1 is put into a superconductive condition, and as a result, the magnetic lines of force in the interior of the material constituting the ice-making vessel 1 are driven out due to the Meisner effect and the ice-making vessel 1 is lifted from the inner wall 4 due to a difference in the density of the magnetic lines of force. Accordingly, the ice-making vessel 1 is apart from the inner wall 4 and the cooling system is converted into an indirect method which depends upon the circulation of air. Hence, as the cooling is carried out slowly, transparent ice can be produced without being frosted.

Abstract: PURPOSE:To decelerate feeding of sheet material without causing fearing etc., by making a slotted hole in the center of a guideboard for mounting the sheet material, and sucking air through an air suction hole made through curved face of the guide when the sheet material is carried along the longitudinal direction of the slotted hole and folded between holding guide members while being decelerated. CONSTITUTION:A sheet material 12 is carried while being held between upper and lower carry belts 14, 15, and a folding blade 24 lowers immediately before the tip of the sheet material 12 contacts with a stopper board 27. The folding blade 24 folds the sheet material 12 along curved guide faces 18a, 19a of folding guide members 18, 19. At this time, carrying speed of sheet material 12 is decelerated because air suction holes 20a, 21a are closed by the sheet material 12 placed on the curved faces 18a, 19a of guide. Consequently, feeding speed of the sheet material 12 can be decelerated by such degree as causing no breaking when the sheet material 12 contacts with a stopper board 27.

Title: Lock protecting circuit for motor
Inventor: AOMORI KOUKICHI
IPC: H02P7/29
Filed: 1981-12-07
Abstract: PURPOSE:To reduce the temperature rating of the motor, by controlling the pulse width of a driving pulse when the motor is locked and a pulse width control signal exceeds a specified value, and stopping the motor quickly. CONSTITUTION:When the motor is locked, the pulse width of the pulse width control signal PS becomes broad, and the pulse width of the driving pulse OP also becomes broad. Then a motor driving current tends to increase. When the upper limit of the pulse width of the driving pulse width OP is restricted, the torque exceeding said restricte value is not generated and the speed is reduced. Therefore, the period of the pulse width control signal PS becomes long, the average value of the driving current is decreased, and the motor is quickly stopped. As a result, the temperature rating of the motor can be remarkably reduced in comparison with the conventional motor.

Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a liquid crystal sealing part by projecting the end of one substrate near a sealing port from the end of the other substrate and providing the projecting part with a sealing material. SOLUTION: The end of the lower electrode substrate 12 near the sealing port 51 of liquid crystals 50 projects from the end of the upper electrode substrate 11 and the length (a) thereof is formed longer by, for example, 2 to 3mm. Namely, the display device has a difference-in-level part between both substrates 11 and 12 and the sealing material 1 is applied on the difference-in-level part. The sealing material 1 is applied on the projecting part of the substrate 12 projecting from the substrate 11, i.e., on the difference-in-level part between both substrates 11 and 12, in such a manner and, therefore, the sealing material 1 rides on the projecting part and the positioning of the sealing part on the inner side of the outermost shape of the liquid crystal display element is possible. Then, the sealing material hardly peels.  Since the difference-in-level part is provided with the sealing material 1, the adhesion area of the sealing material 1 is made wider and the strength of adhesion higher is possible. Consequently, the reliability of the sealing part is enhanced.
