Title: Detector for deposit in water
Inventor: TSUJIMOTO HARUO
IPC: G01V9/00
Filed: 1984-06-27
Abstract: PURPOSE:To prevent the embedment of a pump by providing a hanging type detecting body of which the bottom end contacts with the surface of deposit at a prescribed lower water level and changing the hanging attitude thereof according to the load of a movable weight thereby changing over the on-off of a switch. CONSTITUTION:A detector has the movable weight W for assisting the tilting operation of the hanging type detecting body 2. The bottom end of the body 2 contacts with the surface of the deposit 6 on a water base 5 when the deposit 6 attains the prescribed height H. The hanging attitude is at the same time changed and the detecting body is inverted by the load of the weight W. The cores 2 of a cable are then conducted by the operation of an internally provided switch and a detection signal is transmitted to a prescribed signal function. The body 2 is pulled up together with the weight W by a float 3 and is prevented from being kept embedded in the deposit 6 when the water level in a pump pit rises again. The embedment of the pump and the consequent failure in the pumping up of water are thus prevented.

Title: Thermocompression bonding apparatus
Inventor: WAKIZAKA SHINJI
IPC: H05K3/34
Filed: 1994-05-25
Abstract: PURPOSE:To avoid shorting adjacent connecting terminals of a circuit board when input outer leads of a TAB tape are thermocompression bonded to the circuit board to make conductive connections. CONSTITUTION:A thermocompression bonding head 25 has thermocompression bonding pins 35 disposed at the same pitch as that of input outer leads 11 of a TAB tape 2. These leads are to be thermocompression bonding in the point contact condition by the pins 35 and hence the upper face of the circuit board 3 exposed between adjacent connecting terminals 17 can be hardly heated. As a result, if a solder flows from the terminal 17 of the board 3, it can be quickly cooled to harden.

IPC: H01L21/66
Filed: 1989-05-30
Abstract: PURPOSE:To measure a photoluminescent light emitted from a semiconductor sample and measure the distribution of defects along the depth direction of the semiconductor sample by a method wherein the semiconductor sample is dipped into solution obtained by adding hydrochloric acid to organic solvent to etch the semiconductor sample surface and, at the same time, an exciting light is applied to the semiconductor sample. CONSTITUTION:A sample holder 12 can be taken out of a chamber 11 and, after a sample 14 is attached to the holder 12, the holder 11 is housed in the chamber 11. The chamber 11 is filled with a suitable quantity of solution 13 and the sample 14 is dipped into the solution 13. That is, the sample surface is brought into contact with the solution and the etching of the sample surface is progressed. A light from a light source 15 is intermittently applied to the sample 14 in the solution 13 with a certain interval given by a chopper 16. Carriers in the surface of the sample 14 are excited by the application of the light and, by the recombination of the excited carries, a light is emitted. The emitted light is condensed by a condenser lens 17 and the condensed light is divided by a spectroscope and the photoluminescence is measured. With this constitution, the distribution of defects along the depth direction can be measured.

Title: Seal device for coupling lever for flow rate control valve
Inventor: ISHIDA HIROAKI
IPC: F16K41/04
Filed: 1993-06-04
Abstract: PURPOSE:To improve durability of a seal through the change of a resilient body output according to the change of movement resistance of a coupling lever owing to a seal pressure by movably arranging a holding member between a seal member to work on the coupling lever of a flow rate regulating valve and a resilient body. CONSTITUTION:In a flow rate regulating valve to adjust a flow rate through the passage of fluid through a gap between a valve seat and a valve body, when the valve seat is brought into contact with the valve body, a pressure on the outflow side is reduced to zero based on a pressure on the inflow side. When the valve body is moved, in this diagram, rightward, a coupling lever 4 is moved in the same direction through the force of a closedown spring 13 and the valve body approaches the valve seat, whereby a pressure on the outflow side is lowered. In this case, the reaction force of the closedown spring 13 arranged on the outflow side is decreased, a reaction force to a holding member 11 is also decreased, and a seal pressure on the coupling lever 4 is decreased, whereby movement resistance of the coupling lever 4 is decreased. As noted above, since the reaction force of the closedown spring 13 on which a pressure exerted on an O-ring 10 is exerted through the holding member 11 is utilized to maintain the seal pressure of the coupling lever 4, the magnitude of movement resistance of the coupling lever 4 is caused to be proportional to an output from the closedown spring 13 and movement of the coupling lever 4 is facilitated.

Title: Smoke sensing system
Inventor: KATAZUKI KUNIHARU
IPC: G08B21/00
Filed: 1979-10-15
Abstract: PURPOSE: To increase the working efficiency for checking of the operation, by installing the feed voltage switching means to the smoke sense signal receiver of the storage-type smoke sensing system and then providing the storage time shortening means with which the smoke sensor shortens or turns to zero the storage time in response to the feed voltage change detecting means.  
     CONSTITUTION: In the periodical inspection, the change-over switch of the receiver is switched to lower the feed voltage and then apply it to the amplifying circuit ID. The feed voltage change detecting circuit IA compares the feed voltage with the reference voltage. In this case, the feed voltage is lower than the reference voltage, and thus the voltage of a low level is delivered to turn the switching transistor 33 on, and a connection is given to the resistance 32 to shorten the oscillation cycle of the oscillating circuit IC. Under these conditions, when the smoke is generated and made entered between the light emitting element 16 and the photodetector 17, the cunter 18 counts only the pulses exceeding the threshold level among the output pulses of the circuit ID. As a result, the thyristor 13 conducts to produce the alarm or the like.

Title: Automatic operation device of construction machinery
Inventor: FUJIWARA MASAO

Filed: 1989-05-30
Abstract: PURPOSE:To make it possible to operate a construction machinery automatically by comparing a detected value of a running direction and running distance of the construction machinery with a setting to be set in advance to control the construction machinery in a specific running state.

Title: Readout circuit for fifo memory
Inventor: KUROKAWA HIDEFUMI
IPC: G11C7/00
Filed: 1985-06-20
Abstract: PURPOSE:To prevent a permanent reading operation by providing a timer and starting FIFO read operation regardless of a flag state, and detecting the elapsed time and judging whether the read operation is ended or not. CONSTITUTION:An FIFO read start signal 14 is held at '1' firstly and a readout wait signal 13 is held at '1' to maintain a wait state. At the same time, an enable signal goes up to '1' and the timer 3 begins to clock the time. The state '1' of a readout ready signal (flag output) 1 shows a normal readout state and the state '1' of a time-out signal 6 indicates an abnormal end wherein the signal 1 does not becoms '1' even a specific time after a read-only instruction is actuated, so that the FIFO read 9 is brought under control 8 on the basis of those two factors. When the read error 12 of the output of an FF 10 occurs, a reset signal 11 is set to '1' before the execution of the FIFO read- only instruction and then reset to '0'. Then, when the time-out signal 6 goes up to '1', it is set to '1' and used to preserve information indicating whether the instruction is ended forcibly by the timer 3 or not. This constitution allows a fast FIFO read to be made and prevent the deadlock state of an instruction.
