Title: Testing apparatus of corrosive gas environment
Inventor: SANO KAZUHARU
IPC: G01N17/00
Filed: 1983-04-19
Abstract: PURPOSE:To enable the safe and reliable performance of an environment test corresponding to an actual environment by a method wherein the concentration and flow rate of gases, temperature and humidity in a testing tank are controlled in stepless, in an extremely-low concentration and with high accuracy. CONSTITUTION:Mixed chemical liquids 12 and 13 are heated by a heater 26 so that they can react with each other, and thereby H2S gas and SO2 gas are produced. The mixture of H2S and SO2 gases are sucked into a testing tank 1 by air pumps 21 and 22. Air is introduced from an outside-air inlet 14 into the chemical liquids 12 and 13 through pipes 15 and 16, rises as bubbles, and is mixed in the H2S gas and the SO2 gas. The flow rate and concentration of the H2S and SO2 gases are maintained at prescribed values as required in nonstage by adjusting the quantity of air, the concentration of the chemical liquids, the heating temperature of the heater and the speed of rotation of the pumps, etc. The temperature and humidity inside the testing tank 1 of a heat-insulating structure in which substances 2 to be tested are held can be maintained at arbitrary values irrespective of the conditions of the outside air by means of a heater 4, a cooler 5 and a humidifier 6.

Title: Method for managing number of erasing times for flash memory
Inventor: NOZAWA TAIZO
IPC: G11C29/00
Filed: 1995-03-28
Abstract: PURPOSE: To reduce the side of hardware on the outside of a memory while facilitating the processing of software by managing the number of block erase times in a flash memory. CONSTITUTION: A 3 bite area 5 for storing the number of block erase times of a flash memory 1 is allotted to the end of each block 2. A data indicative of the number of block erase times is written in each area 5 in order to manage the number of erase times of each block. Since the flash memory 1 can not be overwritten and a data can be written only after erasure, the area 5 storing the number of block erase times is retreated to other place when a block is erased and the area 5 is overwritten with the number of erasing times upon finishing the erasure. With such method, the number of erasing times can be determined for each block of the flash memory 1 and a block having the number of erasing times close to the limit can be found easily.

Title: Extension data managing system by card
Inventor: NOMURA MANABU
IPC: H04Q3/58
Filed: 1988-03-25
Abstract: PURPOSE:To simplify the registration work of extension data in a key telephone system by registering the extension data for a terminal telephone set only by inserting a card storing the extension data into the terminal telephone set. CONSTITUTION:When a card 50 storing the extension data is inserted into the card reader 14 of a terminal telephone set 10 in the key telephone system, the extension data in the card 50 is read out by the card reader 14 and it is transferred to a main equipment 20. The transferred data is registered as the extension data of the corresponding terminal telephone set 10 in the main equipment 20 and thereafter service based on the extension data is executed. Thus, when one terminal telephone set 10 is used by the plural number of persons and a user is changed, or when the extension data is erased due to trouble, etc., any complicated registration work is unnecessary.

Title: Tape travel time display system
Inventor: NISHIDA YOSHIHIRO
IPC: G11B27/17
Filed: 1987-03-23
Abstract: PURPOSE:To highly accurately display a tape travel time by executing a digital filter processing to the arithmetic value of the tape travel time. CONSTITUTION:The number of reel pulses indicating the number of rotating pulses counted by a prescribed number for one rotation of a take-up side reel 3 which is counted from the start of winding of the tape is operated from the rotating cycle of the take up side reel 3 and the value for every execution of the operation is digital filter processed. Accordingly, since a new arithmetic value is calculated by taking a correlation with the arithmetic value to a previous time, the measurement error of the reel rotating cycle is not influenced to a tape travel time display value. Thereby, the tape travel time can be highly accurately displayed.

Title: Two-way differential clutch
Inventor: SAIKO MASAAKI
IPC: F16D41/07
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To rotate a sprag in the reverse rotation direction by suitably tilting the sprag in the reverse rotation direction when switched to the reverse rotation direction by stopping after normal rotation by arranging a rotational directional play between a rotary shaft and an output gear to which rotation of the rotary shaft is transmitted. SOLUTION: A pair of outward projecting engaging projection parts 20a are integrally formed in opposed positions in a sleeve 20 fitted around the outer periphery of a rotary shaft 1. Recessed locking recess parts 9a extending to a rotational dirtection on/into which the respective engaging projection parts 20a are locked/inserted, are oppositely formed by a pair on the inner peripheral side of an output gear 9 installed on the outer periphery of the sleeve 20. A rotational directional play S is formed between the engaging projection parts 20a and the locking recess parts 9a.  When an input gear reversely rotates by stopping after rotating in the normal rotation direction, rotation of the rotary shaft 1 stops since the play S is formed, and while the engaging projection parts 20a abuts to the inverse directional wall surface of the locking recess parts 9a, a sprag excellently tilts in the reverse rotation direction. Therefore, rotation in the reverse rotation direction of the input gear is excellently transmitted to the rotary shaft 1.

Title: Surface thermometer
Inventor: KOBAYASHI SEIJIROU
IPC: G01K1/14
Filed: 1990-03-22
Abstract: PURPOSE:To enable accurate measurement of a temperature by making a contact plate retract with a contact part thereof contacting the surface of an object to be inspected to keep a sensor in contact with the surface of an object desired to measure the temperature accurately with a deformation of the contact part convex. CONSTITUTION:At a state of starting a measurement of a temperature, a distance l between both arm parts 6a and 6a of a contact plate 6 is and a width of a base supporting the contact plate 6 is also a value close to it. When a temperature measuring part 1 is pressed onto the surface of an object 15 desired to measure a temperature to increase a contact pressure of a contact part 6b, connecting arms 5 and 5 turns upward centered on a support pin 4 and hence, a distance between both the arm parts 6a and 6a decreases gradually. In this manner, as the distance between both the arms 6a and 6a decreases, a stress increases to bend the contact part 6b outward in a convex, which forces a central part of the contact part 6b fixing the sensor 7 to be pushed to the side of the surface of the object 15 desired to measure the temperature. This keeps the contact part 6b from lifting above the surface of the object 15 to be measured to make it contact the surface exactly.

Abstract: PURPOSE: To improve traveling stability and riding comfort of a road surface traveling vehicle by furnishing a stationary cover made of a non-magnetic material with a sensor coil, providing a permanent magnet on the guiding closed side on a free end of a damper cylinder and providing an evaluation circuit. CONSTITUTION: A vibration damper is connected to a wheel mass by a connecting member 4, and a piston rod 2 is connected to a car body mass through a fixed member.

When the cylinder 1 is pushed up by a non-planar property of a road surface, the magnet 10 moves upward in the coil 8, and voltage in proportion to speed is induced in the coil 8. This induced voltage is transmitted to a filter 20 through a connecting line 12, supplied to a microprocessor 28, and this evaluation circuit eliminates work of the vibration damper and prevents transmission to the car body mass.
