Title: Overheat detection circuit
Inventor: MOTOYUI TOSHIAKI
IPC: H01L21/822
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To realize miniaturization of a chip size and reduction of unevenness in detected temperature. SOLUTION: As the temperature of a power element is increased, the temperatures of a resistor 16 constituting a current source 15 together with P channel MOSFETs 17, 18 and N channel MOSFETs 27, 28, a first diode circuit 14 for subtracting and supplying a forward voltage to a positive-phase input of a comparator 11 with reference to a power-supply line, and a second diode circuit 24 for adding and supplying a forward voltage to a negative-phase input of the comparator 11 with reference to a ground line are also increased. Since the resistor 16 has a positive temperature coefficient, the resistance value thereof is increased and currents flowing through the diode circuits 14, 24 are reduced. The forward voltages of the diode circuits 14, 24 are also lowered.  At this point, a voltage VB of the positive-phase input of the comparator 11 changes with a positive slope, and the temperature gradient thereof is increased along with the rise in temperature. A voltage VA of the negative-phase input changes with a negative slope, and the temperature gradient thereof is increased along with the rise in temperature. When the condition VA<VB is reached, an overheat detection signal is outputted.

Title: Transferring device for ic handler
Inventor: TANAKA NORIYASU
IPC: B65G11/20
Filed: 1986-07-22
Abstract: PURPOSE:To damp the collision with a stopper and suppress a recoiling force by bringing a weight into contact with the back face of an IC and pressing it against a socket when the falling IC approaches a position correctly facing the socket. CONSTITUTION:A ring-shaped weight 6 is suspended by a pin 7 so as to be intersected with the locus of the back face of a package against a falling IC 1. The pin 7 is fitted to the fixed member of an IC handler horizontally and parallelly with the back face of the package. The position of the pin 7 is properly set so that the crossing angle theta between the outer periphery of the suspended weight ring 6 and the arrow (d) is made an acute angle. The falling IC 1 hits the weight 6 and is decelerated. When the IC 1 is brought into contact with a stopper 5, the falling speed has been decelerated and it has been brought into contact with the weight 6, thus the IC 1 having hit the stopper 5 does not recoil, and the decreasing motion is momentarily stopped.

Filed: 1981-10-28
Abstract: PURPOSE:To enable to easily control the oxygen density of hot air by a method wherein the sensible heat in the gas generated during the decaulking work performed with the hot air specially produced for decaulking work is recovered in the heat recovery system in the form of steam and said steam and exhaust  gas after decaulking work are added to the hot air for controlling the oxygen  density of the hot air. CONSTITUTION:The hot air for decaulking work is produced at a hot blast generating furnace 7 and sent from a line 23 through lines 20 and a gas collecting pipe 3 and to a line 24 during regular decaulking work against caulking, which incidentally generates during the recovery of heat performed by the gas of a coke oven 1. In this case, the oxygen density of the hot air is controlled by adding the steam from the line 28 and the recycled exhaust gas after decaulking work from the line 38 to the hot air so as to obtain the hot air with the oxygen density of 3-10% measured with an oxygen densitometer O2I by sampling the hot air from the line 23. Said steam obtained from the line 28 is the sum of the sensible heat of the hot air and the combustion heat produced by decaulking work during the operation of a jet steam layer cooler 5 in the same manner as its operation at the heat recovery of raw coke oven gas.

IPC: H03H17/00
Filed: 1982-09-30
Abstract: PURPOSE:To test and evaluate a sound transmission line on characteristic conditions close to actual room acoustic characteristics without the limitations of time and a place, by providing a circuit group which generates an artificial echo signal. CONSTITUTION:The noise generator 81 of an interior noise generation part 8 generates a white noise, which is passed through a filter 82 having such frequency characteristics that the attenuation from a low frequency range to about 3KHz increases linearly by 5dB at every interval of one octave, setting the level of a Hoth spectrum noise signal to a desired value. An A/D converter 61 of a filter part 6 samples an analog receive signal at specific intervals of time and sends the sampled signal to an adder 9 through a filter 62 and a D/A converter 63. The adder 9 adds an artificial echo signal from the filter part 2 to the Hoth spectrum noise signal from the room noise generation part 8 and sends the sum signal to a terminal 3, so a sound transmitter 10 is tested and evaluated by the conditions close to actual conditions. In the filter 62, an adder 64 sums up outputs of the tapped delay circuit consisting of cascaded delay devices D11-D1n through coefficient multipliers 20-2n.
