Title: Incomplete-ice-melting structure of ice-making machine
Inventor: HIBINO TAKUJI
IPC: F25C1/22
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an incomplete-ice-melting structure of an ice-making machine which is so designed as to melt the incomplete ice in a feed water path surely and efficiently. SOLUTION: A supply water pipe 58 and a return pipe 48 communicating with an ice-making water tank 12 are made to branch from a case 24 of a pump 14. Inside the return pipe 48, a valve disk 62 which is pressed by a biasing means 64 and can close and open a flowing water port 56 is provided. This valve disk 62 is so displaced as to close up the flowing water port 56 under an ordinary pressure P1 acting during the operation of the pump 14, or below, and to open the flowing water port 56 on the occasion when a pressure P2 larger than the pressure P1 acts.  In the case when the ordinary pressure P1 acts on the valve disk 62, in other words, ice making water is made to stay and held in the supply water pipe 58, and in the case when the pressure P2 acts on the valve disk 62 due to formation of incomplete ice, the ice-making water in the supply water pipe 58 is made to flow into feed water paths 20, 36 and 16 through the ice-making water tank 12 so as to melt the incomplete ice.

Title: Disk device
Inventor: WATANABE HIROSHI
IPC: G11B20/14
Filed: 1989-10-30
Abstract: PURPOSE:To always correctly reproduce the data of a block by providing a means to select one of detection mask output means corresponding to the counting contents of a counting means and a detection signal from a detecting means. CONSTITUTION:Corresponding to the detection signal from a synchronous code detecting circuit 45 and a counted number to be supplied from a frame counter 46, it is judged whether a synchronous code is detected at an adaptive position or not, and a detection mask selecting circuit 47 outputs a selecting signal to any one of detection mask output circuits 48a, 48b and 48c corresponding to a judged result. Accordingly, when the synchronous code is not detected in detection mask width or when the detecting position of the synchronous code is deviated from an exact position where the synchronous code appears, the synchronous code can be detected in the detection mask by reproducing data while enlarging the width of the detection mark and the deviation of the data can be corrected by the synchronous code. Thus, the data for the unit of the block can be correctly reproduced.

Title: One-chip microcomputer
Inventor: FUJITAKA SHIGEAKI
IPC: G06F1/12
Filed: 1990-10-16
Abstract: PURPOSE:To ensure the operation of a peripheral unit which uses an external signal as an input even in a wait mode by actuating an external signal shaping circuit with a supplied clock even in the wait mode. CONSTITUTION:A clock generating part 6 can output the division output. That is, the part 6 divides the output of an oscillator circuit 1 and produces a CPU clock to input this to a CPU 3. At the same time, the output of a divider 21 is inputted to an external signal shaping circuit 4 with no intervention of a control gate 22. Thus the circuit 4 can operate even when the CPU 3 carries out a wait instruction and outputs a CPU clockstop signal. Then a counter 5 can count the external signals even in a wait mode.

Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To automatically update a patent management database without omission by extracting new data from a CD-ROM which contains information about a patent application or a utility model registration application and adding it to the patent management database. SOLUTION: This method extracts data to be updated from a distribution destination database and produces a flexible disk 109 for updating by a data-to- be updated transfer function. For the production of a flexible disk of full text, it reads data such as a specification from a CD-ROM 21 and writes it on the disk 109, which is sent to a prescribed patent management device 5. When it is confirmed that the disk 109 is inserted, data of the disk 109 is read into a memory. Subsequently, data updating is performed.

Title: Power unit
Inventor: KANOUDA TAMAHIKO
IPC: H02M3/00
Filed: 1994-10-19
Abstract: PURPOSE: To reduce the number of parts and to miniaturize the power unit by providing at least one operational amplifier having a negative power supply electrode connected to the load side of a current detecting resistor and detecting voltages at both terminals of the current detecting resistor while using the operational amplifier. CONSTITUTION: A positive power supply terminal 57 and a negative power supply terminal 53 of an operational amplifier 7 are connected parallelly with a load 9, the same voltage as applied to the load 9 is impressed to the operational amplifier 7, and power is supplied to the operational amplifier 7. Since an opposite phase input terminal 56 is connected through an input resistor 5 to the connecting point of a main circuit 10 and a current detecting resistor 3, a detecting voltage is impressed to the opposite phase input terminal 56. The impressed detecting voltage is amplified based on the ratio of an input resistor 5 to a feedback resistor 4 and the result is outputted from an output terminal 54. The outputted voltage is made a prescribed multiple of the detecting voltage and this is a voltage proportional to the instantaneous value of a load current.  This voltage is transmitted to the main circuit 10 by a signal transmitting means 8 and used for controlling the load current. Thus, a voltage source for operating the operational amplifier 7 is not used at all.

Abstract: PURPOSE:To prevent the travelling of a car as an antenna is left as it is not installed by displaying a message requiring the mounting of the antenna to a display means even when the mounting of the GPS antenna is forgotten when an ignition switch is turned off for parking under the state, in which a position can be sensed, and the switch is turned on for starting.

Title: Internally buried type micropump
Inventor: TATSUMI KOICHI
IPC: A61M37/00
Filed: 1988-11-08
Abstract: PURPOSE:To make the pump chamber part compact and reduce the load of a user by providing such a constitution as successively disposing the plural steps of pump chambers composed by forming a thin film part of semiconductor material on one surface part along the flow direction of a fluid passage and successively deforming the tin film parts by the electric application thereto to send a liquid. CONSTITUTION:When a voltage is applied to each pair of an electrode part 21 and a thin film part 25 faced to each other in each pump chamber 28 of a fluid passage 17 successively from an inlet port 7 toward an outlet port 9, the thin film part 25 is deflected to the electrode part 21 side to clog the fluid passage 17 in that part. Thus, when the operation of applying a voltage is repeated to successively give a time difference between the electrode part 21 and the thin film part 25 and partially overlap with that of each step successively, each thin film part 25 is deflected with a time difference, a progressive wave from the inlet port 7 toward the outlet port 9 side is formed, and a drug taken in the fluid passage 17 is sent to the outlet port 9 side. Hence, the constitution of the pump chamber 28 part is made compact, and the load of a person using a micropump can be reduced.

Since the parts each having the length (b) which are not cutout are made to remain at both sides of the cutout parts 11 and 12 and cutout parts are not provided at side wall parts 9b and 9d, the tips of corner wall parts 13a-13d corresponding to the sides of a quadrangular pyramid stage extrude from the tips of the side wall parts 9a and 9c. The height (c) of the cutout parts 11 and 12 is determined at a part slightly lower than the upper end of a chip 2. The chip 2 is fixed by using the suction holder 1b formed in this way. Even if a conductive bonding material swells up, the adhesion of the material to the side wall parts 9a and 9c is restricted. The corner parts of the chip 2 are held the suction holder 1b, and the positioning of the chip 2 is achieved.
