Title: Electric precipitator
Inventor: HARA KEIICHI
IPC: B03C3/40
Filed: 1994-06-07
Abstract: PURPOSE:To improve the assimilability and the dust collecting efficiency of an electric precipitator. CONSTITUTION:A dust collecting electrode group 'B' and a discharge electrode group 'A' are arranged in this order to the flow of dust-contg. gas. The discharge electrode group 'A' consists of discharge electrodes 1 each consisting of a metal plate having piercing parts 1a formed punched in a semi-circle so that the semi-circles may be next to each other on the longitudinal edges. The dust collecting electrode group 'B' consists of dust collecting electrodes each consisting of a chain-shaped body. As the chain-shaped body, a commercial swing chain is used without additional work being done. Therefore, labor and time for manufacturing parts are saved, and making light in weight is achieved by used the chain. The discharge electrode group 'A' and the dust collecting electrode group 'B' are oscillatably hung opposite to each other leaving a space between them. As a result, links 10a constituting a chain 10 each freely change their position relationship and are vibrated. Dust accumulated on the chain 10 is easily made to fall by the vibration. Therefore, high dust collecting efficiency is maintained for a long period of time almost without requiring dust removing work such as hammering.

Filed: 1978-11-30
Abstract: PURPOSE:To obtain a thermometer easy to handle by applying infrared rays from an object to be measured and a reference black body to the sensor alternately, by measuring temperature of the black body directly and by obtaining temperature of the object from an electromotive force of the sensor by arithmetic operation. CONSTITUTION:Infrared rays from both the object 1 and the reference black body 2 are alternately applied to the infrared ray sensor 5 that produces an electromotive force corresponding to the quantity of infrared rays. Temperature of the reference black body 2 is measured by the thermal sensor 4, a proportional constant that relates temperature to electromotive force is obtained from both the electromotive force and temperature of the reference black body. The proportional constant and the quantity of infrared rays from the object are operated to obtain temperature of the object. For the reference black body, a disc, for example, is used and rotated, or it is reciprocated up-down or right-left.

Title: Molding die and manufacture thereof
Inventor: KUZUSAKO JUNICHI
IPC: B31B50/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a molding die, even if made of a resin, from becoming weak in strength and thereby, improve the durability, life and productivity at the time of molding by applying a high durability coating to the face including a suction hole. SOLUTION: A highly durable coating is applied to a molding die main body 21 of a hydrophilic resin so that the molding die main body 21 is made durable. That is, the resin molding die main body 21 is dipped into a coating material liquid, then the coating material liquid is applied to the inner and the outer face of the main body 21 including a suction hole 21a, and the surplus coating material liquid is removed to dry the applied coating material liquid. In this case, the hole diameter of the suction hole 21 is securely protected against the coating material liquid so that the suction hole 21 is prevented from becoming clogged at the time of coating. Further, the molding main body 21 covered with the coating material 70 of a desired coating thickness is thermally treated to cure the coating material 70.  Thus it is possible to manufacture a molding die 71 covered with the coating material 70 which is of the desired thickness all over the entire face and highly durable including the suction hole 21a by repeating a sequence of processing steps a plural number of times.

Title: Ultrasonic output supplying method for ultrasonic wire bonder
Inventor: KUME SUSUMU
IPC: H01L21/60
Filed: 1992-05-16
Abstract: PURPOSE:To provide an ultrasonic output supplying method for ultrasonic wire bonding in which deterioration of bonding quality due to deterioration of bonding tool is suppressed while increasing the yield. CONSTITUTION:When a gold wire 2 fed from a capillary 1 is bonded to a member 13 to be bonded through ultrasonic bonding, chips 3 of the gold wire 2 adhere to the tip of the capillary and when bonding operation is repeated, the chips move into the tube of the capillary and adhere thereto. Consequently, performance of the capillary deteriorates to cause deterioration of bonding quality. In order to prevent deterioration, output from an ultrasonic oscillator for driving an ultrasonic oscillator is increased depending on the using frequency of the capillary thus increasing ultrasonic output. This method prevents deterioration of bonding quality even if the capillary is deteriorated.

Title: Amplifier circuit for input of high speed frequency divider
Inventor: MIYAHARA YASUTOKU
IPC: H03G11/00
Filed: 1987-06-17
Abstract: PURPOSE:To make a frequency divider into a high frequency band area without being affected by the amplitude of an input signal and without damaging a frequency characteristic, by providing a filter circuit which eliminates and passes a prescribed frequency band component. CONSTITUTION:The input signal Vin is differentially-amplified by a first amplifying stage 21, and a bipolar signal is taken out by an output stage 22, then, it is inputted to the filter circuit 23. At this time, by setting the capacitance values of capacitors C1 and C2 after decreasing them on the characteristic of a band-pass filter, the gain of a fundamental wave is decreased when the input signal is a low frequency, however, the gain of a high frequency can be maintained at the same level as that of an on- going circuit, and the output waveform of the circuit can be kept constant similarly as when amplitude limitation is performed. In such a way, since it is possible to amplify and output the input signal at a preset level without being affected by the amplitude of the input signal and damaging the frequency characteristic, it is possible to fit the amplitude to allowable input amplitude when it is used in a fast frequency divider, and to make the frequency divider into the high frequency band area.

Abstract: PURPOSE:To perform the control of a plant without degrading the control characteristic by outputting the manipulated variable of a power failure mode in a short-period power failure state and carrying out a normal batch processing in a long-period power failure state respectively. CONSTITUTION:A power failure detecting means 41 starts a timer 42 when a power failure is detected and then starts a deciding means 43 when the recovery of the power failure is detected.

When the power failure time is longer than the set value, the means 43 acquires the mode information from a mode recording part 56. Then a rising program 52 or a manual operation program 55 is selected according to the mode. Finally the selected program is pointed to a reading means 44. In such constitution, the plant is controlled without degrading the control characteristic.
