Patent JP-H0248108-A (JP)
Title: Copy milling processor
Inventor: TANAKA TAKESHI
IPC: B23C1/16
Filed: 1988-08-10
Abstract: PURPOSE:To stop a cutter from piercing a work at its minimum by detecting the displacement of a contact shoe and providing an external operating means which positively displaces a corresponding interval to the contact shoe, in a detecting means. CONSTITUTION:A detecting means C which detects the displacement quantity of a contact shoe 19 and outputs a detecting signal in a compliance with the displacement quantity gives an actuating lever 29 a rotation tendency of clockwise by the action of its dead weight and a plate spring 36. In addition, a mounting rod 38 in the lifting and lowering directions, contact pieces 39, 40 corresponding to the other end of the actuating lever 29 and a pneumatic cylinder 41 are provided. When the contact shoe 19 is disconnected from a model M and falls to a downward end rapidly, the detecting means C detects the displacement and moves a processing head downward. When the actuating lever 29 reaches the position of the contact piece 40, it rotates clockwise resisting the plate spring 36. By this action, the detecting means C moves from a definite position to downward so as to shorten an interval. The interval is made to be a defined distance, and thereby a lifting and lowering motor stops rotating so as to stop a cutter from piercing a work.

Filed: 1992-07-27
Abstract: PURPOSE:To eliminate sealing of resin with inclination of a semiconductor chip and exposure of leads, a placing part and metal wirings which must be originally covered with resin due to flow of the resin to be poured. CONSTITUTION:A method for sealing a semiconductor device with resin and a mold therefor comprise pins 16 for supporting a placing part of a lead frame 2 of a sealed semiconductor chip 1. The pins 16 are retreated before resin is poured in a cavity 15 and started to be cured (crosslinked), and moved to a position where its end coincides with a surface of the cavity 15. Thus, an inclination of the chip due to flow of the resin and exposure of components from the resin due to the inclination are prevented.

Title: Detection of condition of alloying reaction surface
Inventor: MARUI TOMOTAKA
IPC: G01J9/04
Filed: 1993-08-11
Abstract: PURPOSE:To improve the accuracy of an alloying process by detecting a state and a temperature during a reaction by measuring the state of an alloying reaction surface and a surface temperature. CONSTITUTION:The characteristics of the spectral emissivity epsilonlambda of a wavelength lambdaare assumed by epsilonlambda=exp{a/((lambda)<1/2>+b/lambda)} while using (a) and (b) as parameters, and the assumption formula is acquired by applying spectral emissivity to two different wavelengths lambda1, lambda2 to epsilon1 and epsilon2 respectively. A parameter value a=(lambda1 INepsilon1-lambda2Inepsilon2)/((lambda1)<1/2>-(lambda2)<1/2>) given by the following formula is obtained from a luminance energy signal in two wavelengths lambda1, lambda2, and emissivity epsilon is not determined because a temperature cannot be measured by a thermocouple on an on-line, but the value of (a) can be computed when the luminance temperature signal (luminance energy) of a radiation thermometer in two wavelengths lambda1, lambda2 is observed on the on-line. The state of a surface can be decided by the value of (a).

Abstract: PURPOSE:To improve the quality and manufacture efficiency and to simplify the device by providing a reservoir means for liquid crystal which deforms when heated up to predetermined temperature to drip the liquid crystal on the liquid crystal injection port of a liquid crystal element arranged below. CONSTITUTION:A liquid crystal container 33 is fixed on the flank of a vacuum tank 31 with a support rod 32 made of shape memory alloy. The vacuum tank 31 is evacuated to foam the liquid crystal 34 in the container 34 and then the liquid crystal 34 is heated by an infrared-ray lamp 36 to become liquid having low viscosity and further foamed. The support rod 32 is deformed by carrying on the heating and the liquid crystal 34 is dripped on the injection port of a liquid crystal cell 21. The dripped liquid crystal 34 is injected into the liquid crystal cell 21 through the injection port. Consequently, no air bubble is formed in the liquid crystal cell, so the quality of the liquid crystal cell is improved and the liquid crystal is dripped by a fixed amount corresponding to the liquid crystal storage space, so the loss of the liquid crystal is small and the manufacture efficiency is improved. Then no complex control is required, so the device can be simplified.

Title: Direct digital synthesis type signal generator
Inventor: KONDO SATOSHI
IPC: H04B1/713
Filed: 1994-08-25
Abstract: PURPOSE: To minimize the level of carrier waves at the time at switching the frequency and to reduce the spread of noise spectrum at the time of switching the frequency by passing the frequency switching signals of rectangular waves through a low-pass filter and generating amplitude limiting signals. CONSTITUTION: Plural pieces of Δθ which are frequency set values are stored in a frequency table 1 beforehand. The frequency table 1 judges the level rise of the frequency switching signals 100 as a frequency switching timing, successively selects one from the plural Δθ and outputs the Δθ. Thus, the frequency is switched by the rise of the frequency switching signals 100. The frequency switching signals 100 are shaped into the amplitude limiting signals 105 in the low-pass filter 5 and supplied to the reference input terminal of a digital/analog converter 4. That is, by turning the amplitude limiting signals 105 to the reference level signals of the digital/analog converter 4, the amplitude of the carrier waves 104 is limited only at the time of switching the frequency and the spread of the noise spectrums is reduced.

Filed: 1986-08-27
Abstract: PURPOSE:To attain the quick and easy change and control of a formula model by separating formula arithmetic function from a process control computer main body as a compact portable computer and then as an independent computer exclusive for formula model. CONSTITUTION:A process control computer main body 1 is connected to a connection equipment 3 via an input/output device 2 for control of the equipment 3. A formula model arithmetic executing function is separated from the main body 1 and formed into a package as a compact portable computer. Thus it is possible to constitute a computer 5 exclusive for formula model which is connected to the main body 1 via a standard interface 4. Therefore, the formula model of the compute 5 is changed, corrected and controlled by a substitute computer different from the computer 5 which is set under an on-line working mode.

Title: Method for sealing porous body
Inventor: NISHIMURA MASATO
IPC: C23C16/44
Filed: 1989-08-01
Abstract: PURPOSE:To perfectly seal a porous body and to obtain a dense product at the time of impressing a high frequency wave on the porous body to seal the body by CVD by gradually lowering the high frequency power as the reaction of the gaseous reactants proceeds. CONSTITUTION:A high-frequency wave is impressed on a porous body in the atmosphere of gaseous reactants (e.g. TiCl4 and BCl3) to heat the body. The gaseous reactants are allowed to react with each other to deposit a conductor (e.g. TiB2) by CVD, and the body is sealed. In this case, the high frequency power is gradually lowered as the reaction of the gaseous reactants proceeds to control the induction heating of the conductor. The reaction of gaseous reactants on the surface part of the pore in the body is thus controlled, and the clogging of the part is prevented.
