Title: Core and removing method thereof
Inventor: TOMITAKA SHUICHI
IPC: B22D29/00
Filed: 1995-06-29
Abstract: PURPOSE: To enable pull-out of the whole core from a cast product by enabling the shrinkage of a core resin part at the time of becoming the soft condition to easily shrinkage-deform the whole core. CONSTITUTION: Molten metal is poured into a cavity between a metallic mold and the core, and solidified to cast the cast product. An undercut or the cavity part in the cast product is formed with the core 1. This core 1 is constituted with the thermoplastic resin and formed with the core resin part 3 constituting the part at least contacting with the molten metal in this core, and the shrinkable structure formed in the core resin part 3 so as to be possible to shrink the core resin part 3 when the temp. of the core resin part 3 raises and becomes the soft condition. The shrinkable structure 4 is constituted with a hollow part or gas hole parts 4A formed in the core resin part. At the time of pulling out the core 1 from the product, the core is pulled out while applying the fine vibration and twist force, etc.  By this method, the pull-out force can be transmitted in the soft condition and the whole core can be pulled out.

Title: Relay exchange type multiplex system
Inventor: OZASA KENICHI
IPC: H04J3/06
Filed: 1990-06-25
Abstract: PURPOSE:To improve the multiplex processing efficiency by providing a relay exchange function in a time division multiplexer. CONSTITUTION:When a call comes through a voice interface 16, a time division switch 31 of a relay exchange unit 25 extracts a real voice signal and a signaling data from a time slot of the call data, a path assignment section 32 sends only the extracted signaling data to establish the call between exchanges. When the path assignment section 32 detects a reply signal from an opposite exchange, an exchange control section 33 revises the assignment including a voice data rearranged in advance. Moreover, when a traffic monitor section 34 detects a time slot not in use, the section 34 inserts information representing the allocation state to a time slot of voice assignment information and sends the resulting information. The data of each channel is subjected to multiplexing and demultiplexing at reception through the operation reverse to that above at a time division multiplexer.

Title: Occupant restraint crash protection device for vehicle
Inventor: MIDORIKAWA YUKINORI
IPC: B60R22/44
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To dispense with a displacement detecting device so as to reduce manufacturing cost and to simplify constitution by providing a means for driving a motor according to the detected result of a seat belt wearing detecting device. SOLUTION: A driving part 11 of a DC motor 10 controls the DC motor 10 on the basis of a control signal from an MPU 14. The MPU 14 judges whether a seat belt is pulled out, by the polarity of terminal voltage (v) of the DC motor 10, and judges whether winding of the seat belt is completed, from a flowing current (i). A buckle connection detecting part 16 detects whether a tongue of the seat belt is mounted to a buckle and released from the buckle, and outputs a corresponding control signal to the MPU 14. The DC motor 10 is driven to rotate normally or reversely by a signal from the MPU 14. An expensive displacement detecting device for controlling driving of the DC motor 10 can therefore be dispensed with.

Title: Electronic ring trip circuit
Inventor: INISHI EIJI
IPC: H04M3/02
Filed: 1979-12-20
Abstract: PURPOSE:To make small the size of a ring trip circuit and to make circuit integration, by detecting the formation of DC loop due to off-hook of a terminal device with a voltage comparator. CONSTITUTION:A terminal device 1 and a 16Hz oscillator 2 are located outside the electronic ring trip circuit. When the 16Hz AC callout signal from the oscillator 2 is given to a terminal device 1 via a resistor R1, the terminal device 1 in on-hook state produces a callout tone. After the callout signal is rectified at half wave at a diode D2, it gives an ON/OFF signal to a transistor TR6 via an OP amplifier 7. When the terminal device 1 is in off-hook, since the resistance value of the terminal device 1 is lowered to form the DC loop, a voltage of low potential is obtained at the output of OP 4 stably. The logic level detects the off-hook of the terminal device 1 to stop the call-out signal. Thus, the circuit integration and small sized device are obtained.

IPC: G06K9/62
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To recognize with high accuracy the characters which are similar to each other based on the single feature value. SOLUTION: The feature value of an input character pattern is extracted (101) and compared with the standard feature value of a dictionary 107 for calculation of a virtual difference degree between both values (102). A candidate character selection part 103 selects the candidate characters in order of lower virtual difference degrees. A difference degree correction decision part 104 decides whether the virtual difference degree should be corrected. If the difference degree should be corrected, a difference degree correction part 105 corrects the virtual difference degree to obtain a new difference degree based on a component having a high degree of separation between similar characters that is obtained at a feature value component selection part 110. Then a candidate order decision part 106 rearranges the candidate characters in order of corrected difference degrees.
