Title: Semiconductor device
Inventor: KOBAYASHI KAZUHIRO
IPC: H01L23/50
Filed: 1992-09-17
Abstract: PURPOSE:To reduce contact resistance between a wiring board and an outer lead terminal by ensuring the quantity of solder for bonding the outer lead terminal of a sealing package, at the tip thereof, to the wiring board mounting the sealing package of semiconductor substrate. CONSTITUTION:An outer lead terminal 2 is projecting from a side of a sealing package 1. A beveled part 4d is formed between the contact face 4b with a wiring board 3 and a side face 4a at the tip 4 of the outer lead terminal 2. Since the quantity of solder 5 for bonding the tip part 4 of the outer lead terminal 2 to a wiring board increases, contact resistance between the tip 4 of the outer lead terminal 2 and the wiring board 3 is decreased.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/64
Filed: 1986-10-17
Abstract: PURPOSE:To improve signal to noise (C/N) at a short wavelength by using a thin ferromagnetic metallic film which is amorphous for a medium formed by laminating a fine particle coated layer and the thin ferromagnetic metallic film on a high-polymer film. CONSTITUTION:The thin ferromagnetic metallic film 5 which is amorphous is used for the medium formed by laminating the fine particle coated layer 2 and the thin ferromagnetic metallic film on the high-polymer film 1. The amorphous film 5 is made of Co-O, Co-Fe-O, etc., so that coercive force is assured by shape anisotropy and the finer particles. The partial change in the magnetic characteristics by the strain generated in the magnetic recording layer by the stress which the projecting parts receive under high speed sliding with a magnetic head and the consequent change in a recording level and increase in modulation noise are thereby decreased to a negligible level and the good C/N is maintained without increasing modulation noise even if the recording wavelength is short.

IPC: A61K9/00
Filed: 1983-12-26
Abstract: PURPOSE:To provide the titled composite capable of releasing the physiologically active component at a constant rate for a long period, by hot-pressing a carrier with a mold, placing a physiologically active substance in the cavity of the molded carrier, covering the substance with the carrier, and again hot-pressing the product.

A physiologically active substance is placed at the center of the cavity, covered with the carrier, and hot-pressed with a flat press to obtain a slow-releasing composite having sandwich structure. The hot-pressing is carried out preferably at 20-300 deg.C and 50-10,000kg/cm<2> pressure. The releasing rate of the physiologically active substance can be suppressed by irradiating the sandwiched product with light or ionizing radiation after the hot-press with the flat press. The carrier is e.g. amino acid, hemoglavin, etc., and the physiologically active substance is an anti- malignant tumor agent, a hormone preparation, etc.

Title: Automatic checking device of water service meter
Inventor: ABE TAKESHI
IPC: G01F15/06
Filed: 1983-12-26
Abstract: PURPOSE:To make it possible to perform a read instructing operation in a simple manner without the need for a checker to put a hand in a narrow space for the operation when checking a meter, by opposing the fore end of a read instructing bar separately to a signal receiving means on the meter side. CONSTITUTION:The rotation of an impeller 2 supported axially and rotatably in a water channel 1 is detected by a detecting unit 6 and delivered therefrom as a rotation pulse S1 to a counting circuit 10 of a signal processing unit 7, where it is counted and accumulated. Then, it is displayed as an accumulated flow rate, i.e. a quantity of water used, in a display unit 8, while a data signal S2 is sent to a signaling circuit 11 simultaneously. When a water service meter is checked, a magnet 16 provided in the fore end of a read instructing bar 15 carried by a checker is opposed closely to a magnetic sensor 14 of the meter. Thereby a read instruction signal S4 is delivered to the signaling circuit 11 and a radio control circuit 12, a radio transmitter 9 is thereby put in the state of transmission, and thus the delivery of a transmission signal S3 representing the accumulated flow rate or the like is started.

Patent JP-S61129364-A (JP)
Title: Power steering device
Inventor: KOZUKA HAJIME
IPC: B62D6/02
Filed: 1984-11-26
Abstract: PURPOSE:To minimize the torque of steering when the steering is effected upon low speed running, by providing an unloader valve for closing oil passaged for a vehicle speed responsive type flow control valve and a reaction force piston. CONSTITUTION:When a vehicle comes to be in its low speed condition, a control device 15 receives a pulse signal from a vehicle speed sensor 14, and shifts a flow control valve 13 in the left direction. Then the hydraulic pressure of an oil passage 7f comes to be lower than that upon stopping of a vehicle. At this time, when a steering wheel is turned, the pressures of passages 7d, 7f are raised. These pressures are transmitted to a spool in a pressure control valve 12 to increase the hydraulic pressure of the oil passage 7d higher than that upon stopping of the vehicle. At this time, a spool in an unloader valve 19 is raised up and is then held to close passages 7c1, 7c2. The pressure in a chamber 6 in the rear of a reaction piston 5 comes to be zero so that the discharge characteristic of a pump is set such that the torque of steering is effected by a torsion bar alone.

Filed: 1989-09-25
Abstract: PURPOSE:To increase the initial loading speed of a file by discriminating the loading method of the file based on a check code in a management table and accessing a disk based on the management table in the case of direct loading. CONSTITUTION:A processor 1 discriminates the loading method of the file based on the check code in a management table 8 which is stored in a non- volatile memory 7 backed up with a battery 6. In the case of direct loading, an auxiliary storage device (disk) 4 is accessed based on the physical address and the size on the auxiliary storage device 4 of each block of the file stored in the management table 8 to directly read the required file. Thus, unnecessary access to the auxiliary storage device is prevented to shorten the time required for initial loading of the file.

Title: Redundancy switching system for optical transmitter
Inventor: NOMURA KENICHI
IPC: H04B10/032
Filed: 1988-10-04
Abstract: PURPOSE:To prevent momentary breaks of optical output to a transmission line by extending the pulse width of a request signal, which requests an optical transmitter to output light beams, to delay change from the turning-on state to the turning-off state and stopping the output of the current optical transmitter after output of light beams from a stand-by optical transmitter.

The other has the logic inverted by an inverting circuit 4 and is inputted to a pulse width extending circuit 6 and has the pulse width extended to delay the change from the (H) level to the (L) level of the request signal, which requests an optical transmitter 2 to output light beams, and is inputted to the optical transmitter 2. Thus, light beams output of the optical transmitter 1 and that of the optical transmitter 2 overlap.
Patent JP-H06101887-A (JP)
Title: Method for controlling air-conditioner
Inventor: OTSUKA SHINJI
IPC: F25B13/00
Filed: 1992-09-18
Abstract: PURPOSE:To prevent the comfortableness from being impaired by setting an air flow rate of an indoor unit to the maximum only for a specified time at the time of restarting room heating when the period of defrosting operations is short and a set air flow rate mode before the defrosting operation is started is a reference value or less. CONSTITUTION:When a defrosting operation is finished, a room heating is restarted. When the temperature of an indoor heat exchanger 5 becomes a specified value, an indoor unit control unit 6 starts the operation of an indoor blower 9 in the same air flow rate mode as a set air flow rate mode before starting the defrosting operation which is previously executed. In this case, when the interval between the N-th defrosting operation and the (N+1)-th defrosting operation is, for example, shorter than a specified time and an air flow rate mode of a room heating set before the (N+1)-th defrosting operation is started is a reference value or less, an air flow rate of the indoor unit is set to the maximum only for a specified time when a room heating is started after the (N+1)-th defrosting operation is finished. Thus, the indoor temperature lowered so far can be rapidly raised.
