Title: Ice making device
Inventor: TAKEUCHI WAKICHI
IPC: F25C1/24
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent putrefaction of water or the generation of odor by connecting a suction side of a reversible self-absorbing pump to a water supply tank and turning reversely the pump for a definite time when water supply operation is not executed over a definite time after water is supplied to an ice making pan. SOLUTION: The water in a water supply tank 7 is absorbed with a pump 6 and is discharged from a nozzle 13 by way of pipe connecting members 35 and 71 and a pipeline 9 from a pipe 36. Then the pump 6 is switched over reversely and adapted to stop the discharge of water from a nozzle 13, thereby ending a series of water supply processes. The water in the ice making pan 2 is connected and the ice making pan 2 is turned back with an inversion device 3 so as to separate ice, thereby dropping the ice into an ice storage vessel 5 and repeating the water supply processes again until the ice storage vessel 5 is filled with ice.  Therefore, when much ice is not used in a winter season, a suspension time continues long so that the pump 6 is turned reversely for a definite time so as to inhibit the growth of bacteria in the water when a control circuit fails to execute a water supply operation for more than a definite time.

Title: Battery
Inventor: UMEO YOSHINORI
IPC: H01M4/48
Filed: 1982-12-17
Abstract: PURPOSE:To improve battery performance while preventing the increase in internal resistance of a positive electrode active material as well as increasing the filling amount of said material by covering the surface of said active material grains with an electrically-conductive material. CONSTITUTION:A positive electrode active material made of power whose surface is covered with an electrically-conductive material is used. For instance, manganese dioxide is heated under reduced pressure or in the atmosphere, and carbon is deposited on the manganese dioxide powder surface through e.g., sputtering process. A battery is constructed by adding a binder to this manganese dioxide as a positive electrode black mixture. Hereby, it is possible to sufficiently fill the positive electrode active material by a fraction by which the conductive material is essentially reduced, while reducing contact resistance between the active material and the conductive material since the conductive material is added not in the state of mixture but exists in a state where the grain surface is covered thus allowing a battery excellent in discharge performance to be obtained.

Filed: 1987-09-07
Abstract: PURPOSE:To prevent the biting action of a rolling contact gear, generated when a braking member brakes a reel stand by detaching mechanically the rolling contact gear from a reel gear always at the time of the braking of a reel. CONSTITUTION:The friction member 6b of a reel stand braking member 6 is fixed to the braking member 6 by an adhesive, etc., and is pressed and brought into contact with the braking cylinder part 2b of the reel stand at the tie of the braking. Besides, when the rolling contact gear 3 is engaged with the reel gear 2a at the time of the braking, a projection 6a, formed on the braking member 6, abuts the projection 5a, provided on a rotating member 5 for rolling contact, and rotates the rotating member 5 for rolling contact.

Thus, at the time of the reel braking, at first the rolling contact gear 3 is mechanically detached from the reel gear, and besides, the braking member is used in common for cutting off the transmission of reel rotation and for the reel braking. Thus, the bite of the rolling contact gear due to the reel braking can be prevented.

Title: Bit block transfer control device
Inventor: YAMAMOTO KENICHI
IPC: G06F13/38
Filed: 1989-08-30
Abstract: PURPOSE:To reduce the number of times of interposing precharge time, and to shorten the processing time of bit block transfer by reading out and shifting continuously the data of plural words, and writing it in continuously. CONSTITUTION:A bit block transfer circuit 16 reads out the plural words of the data continuously by controlling a dynamic RAM (random access memory) control circuit 18, and stores the read-out data in a temporary storage memory 16a, and simultaneously, shifts it according to set shift quantity. Subsequently, the bit block transfer circuit 16 executes control to read out the data of plural words from the temporary storage memory 16a and write this data continuously in the destination of a dynamic RAM 17. Thus, since the interposing precharge time is limited to only one time respectively at the time of read-out and at the time of write-in, the processing time of the bit block transfer can be shortened.

Title: Passive ring resonance-type optical gyro
Inventor: KATAOKA IZUMI
IPC: G01C19/72
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To obtain a passive ring resonance-type optical gyro by which the detection performance of an input angular velocity is enhanced by a method wherein an optical filter which makes the frequency distribution of a laser beam narrow is interposed between a laser light source and a ring resonator. SOLUTION: A laser beam which is radiated from a laser light source 1 is passed through a narrow-band optical filter 9 so as to be changed into a narrow band, and it is incident, via an optical directional coupler 13, on a ring-shaped optical path 4 (a ring resonator) which is constituted of a partial translucent mirror 2 and of mirrors 3, 5, 6. A part of the laser beam which is turned by the ring resonator is taken out via the optical directional coupler 13. When a circulating beam which has been taken out is made to interfere with the incident beam which is incident on the optical directional coupler 13, a peak is formed on a photodetector 7.  In a passive ring resonance-type optical gyro, the difference in the resonance frequency of the resonance peak between a laser beam turned in the clockwise direction and that of a laser beam turned in the counterlockwise direction is detected, and an input angular velocity is detected. Since the half width of the resonance peak becomes narrow, the resonance peak can be separated easily, and the resolution of the optical gyro us enhanced.

Title: Frame relay communications controller and frame communications controller
Inventor: KAWASHIMA MASANORI
IPC: H04L29/08
Filed: 1993-08-17
Abstract: PURPOSE:To multiplex plural data in a frame relay bearer service level by processing a frame of a frame relay as a flow of plural different data based on the difference from a command/response. CONSTITUTION:When a transmission request of user information or control information takes place, transmission information is stored in a frame (FR frame) of a frame relay. When the transmission information is user information sent by a user information processing section 305, a command/response(C/R) control section 304 sets the C/R of the FR frame to '0' and when the transmission information is control information sent by a control information processing section 303, the command/-response(C/R) control section 304 sets the C/R of the FR frame to '1' and the FR frame is sent to an RF communications equipment of an opposite party. Furthermore, when the FR frame is received, the control section 304 checks the C/R and transfers the information to the section 305 or the section 303 depending on '0', '1' of the C/R. Thus, the FR frame is processed as a flow of plural different data depending on the difference from the C/R and the data are multiplexed.
