Title: Heat exchanger
Inventor: NISHIMURA MOTOHIKO
IPC: F28F1/40
Filed: 1988-01-14
Abstract: PURPOSE:To reduce the possibility of generation of thermal stress by forming a vapor flow-in window in a heat transfer tube and by forming a vapor flow path to an upper water chamber in a cylinder by inserting a heat transfer accelerator thereinto so as to provide a thermal insulation layer between the heat transfer accelerator and the inner circumferential surface of a heat transfer tube communicating hole, as well as the inner circumferential surface of the upper end part of the heat transfer tube, respectively. CONSTITUTION:Water in a heat transfer tube 1 is adapted to flow through an annular flow path 48 having small sectional area and formed between the inner circumferential surface of the heat transfer tube 1 and the outer circumferential surface of an inner solid cylindrical rod 42, and this serves to increase the mass speed inside the heat transfer tube 1, whereby the heat transfer efficiency at the hat transfer surface is improved. Heat exchange is then made between water and liquid sodium, and vapor generated is then allowed to move upwardly through the annular flow path 48. When vapor reaches the upper end portion of the heat transfer tube 1, it is allowed to enter a vapor flow path 43 through a vapor flow-in window 41 formed around the lower end part of the cylinder 40 so as to flow into an upper water chamber 12 since a thermal insulation layer 45 is formed between the inner circumferential surface of the upper end part of the heat transfer tube 1 and the inner circumferential surface of a heat transfer tube communicating hole 31 of an upper tube plate 11 and the outer circumferential surface of a cylinder 40 at the upper end part of a heat accelerator 38 in such a manner as to choke the same. Vapor fed into the upper water chamber 12 is adapted to flow out in the direction shown by arrow head D.

Title: Reel disk driving device of magnetic tape reproducing device
Inventor: MIYAMOTO RITSU
IPC: G11B15/26
Filed: 1985-01-18
Abstract: PURPOSE:To simplify mechanism and to reduce the size of a device by providing a roller assembly which has a slip clutch incorporated between a reel motor and a swing idler and uniting respective members of the roller assembly in search mode. CONSTITUTION:When forward searching operation is performed during reproduc ing operation, a pinch roller leaves a capstan and an arm 37 rotates, so that a coupling gear 36 engages both the 1st and the 2nd gears 29 and 30 as shown by an alternate long and two short dashes line. Therefore, the relay roller assembly is united and a roller 28 is driven by the reel motor 33 through the gears to rotate. A take-up side reel disk 23 is rotated by the roller 28 through the swing idler 38 to have large torque corresponding to the output torque of the reel motor 33 in the take-up direction of a tape. When backward search ing operation is performed, the reel motor 33 reverses and the roller 28 rotates counterclockwise to move the swing idler 38 to left until it abuts on a payoff reel disk 22, performing operation in the opposite direction thereafter. Thus, the structure is simplified and reduced in size.

Title: Apparatus for inspecting terminal press bonded part of terminal press bonded electric wire
Inventor: KOBAYASHI MASAKAZU
IPC: G01N21/84
Filed: 1985-01-17
Abstract: PURPOSE:To inspect the presence of the cutting of a conductor, by measuring the dimension of a conductor part in the longitudinal and lateral directions thereof on the basis of the image data obtained by picking up the image of the terminal part of an electric wire, of which the cover was peeled off, prior to terminal press bonding to compare the same with a tolerant dimension. CONSTITUTION:When one terminal of an electric wire, of which the conductors were entirely or partially cut when a cover was peeled off by a wire stripper, reached the position opposed to a stroboscopic light source 8 and a television camera 8b by the revolution of an arm 3, said terminal is detected by a photosensor 8c and a light source 8a emits light and the camera 8b picks up the image of the terminal of the electric wire and stationary image data is taken in RAM10. CPU11 reads the image data from RAM10 to calculate the dimension of a conductor part in the longitudinal and lateral directions thereof. Next, a tolerant dimension is read from ROM12 and, when the measured value is smaller than the tolerant value, inferiority is judged. By this method, the presence of the cutting of the conductor of the terminal press bonded part can be certainly detected prior to terminal press bonding by simple constitution.

Filed: 1991-01-25
Abstract: PURPOSE:To improve the use efficiency of the optical disk for the original data by providing a defective portion position information registor storing the defective portion position information of the optical disk and the substituted portion position information paired with it. CONSTITUTION:The deflective portion position information and the substituted portion position information paired with this are read out from the defective portion substituted portion position information storing part of the optical disk 2 with the recording and reproducing heads 3a, 3b and is supplied to the defective position information registor 7. Hence before the upper priority unit performs the recording and reproduction of the data, the defective portion substituted portion position information is read-out from the optical disk 2 and it is stored in the defective position information registor. Then since it is unnecessary to build-up the redundant data owing to correct the error for the data in the defective portion, the storage region of the optical disk 2 used for the original data increases and the use efficiency of the optical disk 2 is increased.

IPC: H03M1/36
Filed: 1992-01-20
Abstract: PURPOSE:To improve the resolution equivalently without increase in number of comparators by applying two reference voltages whose voltage varies regularly with a same phase and at a same voltage ratio to a resistance string to obtain a comparison voltage. CONSTITUTION:A reference voltage generating circuit 11 generates reference voltages VFT, VZT changing regularly at a same phase and a same voltage. Then the reference voltages VFT, VZT are fed respectively to one terminal 12A and the other terminal 12B of a resistor array 12. Plural comparison voltages VC1-VCn are outputted from the resistor array 12. Moreover, a comparator array 13 compares the comparison voltages VC1-VCn with an analog input voltage VIN respectively and an encoder 14 encodes an output of the comparator array 13. Since plural digital outputs are obtained from the one analog input voltage VIN by implementing digital conversion under plural conversion characteristics changing regularly in this way, when an averaged digital output is used from the plural digital outputs, it is equivalent to the case that the voltage is decreased by one least significant digit.

Title: Driving device for piezoelectric element
Inventor: MITSUYASU MASAKI
IPC: F16K31/02
Filed: 1989-01-18
Abstract: PURPOSE:To prevent the lift of a valve member by the pressure wave when a valve is closed by providing a high-voltage generating device, a charge switching circuit, voltage changing means gradually changing the applied voltage to a piezoelectric element from the first preset voltage to the second preset voltage, and a discharge switching means. CONSTITUTION:When a piezoelectric element 117 is charged and the valve closing force is generated on a valve member 103, a charge switching means 5 charges the element 117 with the high voltage of a high-voltage generating means 3 to 600V (first preset voltage). As a result, the expansion quantity of the element 117 to close the valve tends to become larger than the shrinkage quantity of the element 117 to open the valve. A large valve closing force is generated on the valve member 103 by that much. The secondary valve opening occurs instantly when the valve is closed, thus a large valve closing force is not required subsequently, voltage changing means 7 and 7' set the initial charging voltage to 600V and gradually change it to the lower valve opening voltage 500V (second preset voltage), and the valve closed state is maintained in a relatively long valve closing period.

Thus, the cell which normally operates at low and high voltages is obtained.
