Title: Automatic working condition switching apparatus
Inventor: OBARA HARUKI
IPC: B23H7/02
Filed: 1980-03-29
Abstract: PURPOSE: To automatically switch to electrical working conditions in accordance with the thickness of a work by changing a peak current of a working power source depending upon the result of calculation of a representation of an optimum working condition.  
     CONSTITUTION: In an apparatus in which working speed is controlled such that an average working voltage between a wire and a work is kept constant, an arithmetic unit ART receives as inputs thereto a working speed F detected from feed pulses f 0  or speed command value c 0 , a peak working current Ip or an average working current Iw, and constants K and F 0  obtained by experiments, and calculates a representation of an optimum working condition (F-F 0 )I 0 -K or (F-F 0 ) I 0 -K. The peak working current I 0  is thus increased or decreased so that the result of the calculation may be made zero.

Title: Video signal reproducing device
Inventor: KOSUGI HIROSHI
IPC: G11B7/005
Filed: 1985-02-28
Abstract: PURPOSE:To improve the quality of reproduced video pictures by detecting a spurious noise component by synchronous detection of a carrier frequency component of a demodulated video signal and that included in a reproduced signal and compensating the detected component. CONSTITUTION:A video FM signal is extracted from the reproduced signal due to a head 3 through a BPF11 and is demodulated by a video signal demodulating part 10. This demodulated signal VID is processed by BPFs 30 and 40 of a video signal compensating part 20 to separate audio carrier frequency components VIDA1 and VIDA2. The component VIDA1 and an audio carrier frequency component RFA1 of the first channel separated form the reproducing signal passing a BPF32, etc. are processed by synchronous detecting circuit 31 and an LPF34 to detect the spurious noise component included in the signal VID, and the level of the signal RFA1 is equalized to the level of the spurious noise component by a level adjuster 35. The same operation is performed with respect to the second channel, and the spurious noise in the signal VID is eliminated by an adder 22 to obtain distinct reproduced video pictures of high quality.

Title: Preparation of high-purity benzene
Inventor: TAKAHASHI HIDEYUKI
IPC: C07C7/12
Filed: 1978-04-10
Abstract: PURPOSE: To obtain high-purity benzene procuring the JIS standard acceptance, by combination of distillation of crude benzene cut from the dealkylation step of hydocarbons containing aromatic cones with treatment with an active substance.  
     CONSTITUTION: The hydrocarbons 11 containing aromatic ones are hydrogenated and dealkylated in the dealkylation step 12, and the resulting product is distilled to remove light fractions having a boiling point lower than that of benzene. The resulting crude benzene fraction 13 (the first stage) is then distilled in the distillation step 14 to give substantially pure benzene 15 containing small amounts of olefins and  thiophenes. The aromatic hydricarbons other than benzene are discharged from the  outlet 16 (the second stage). The benzene 15 is treated with an active substance,  e.g. clay, at room temperature to 120°C in the treating step 17 to remove the impurities of olefins and thiophenes (the third stage), thus giving the high-purity  benzene 18.

IPC: H01L21/3065
Filed: 1982-03-15
Abstract: PURPOSE:To perform fine work by a method wherein expansion of an oxide film in terms of thickness resulting from oxidation is made use of in a self-alignment manner in a process wherein oxidation proceeds under an acid-resistant insulating film produced by selective oxidation or wherein a thin film layer is coverted into an oxide film in a high temperature O2 atmosphere. CONSTITUTION:A poly-Si film 13 and then an Si3N4 film are formed on an Si3N4 film 12, and photoetching is performed for the formation of a pattern 14' with its width measuring about 2mum. The poly-Si film 13 is oxidized as a selective oxidized mask for the formation of an SiO2 film 15. The SiO2 film is formed also as oxidation proceeds under the pattern 14', whereafter a poly-Si film pattern 13' remains with a superficial pattern width m of about 0.4-0.6mum. When the remaining poly-Si film 13'' is completely oxidized, SiO2 film patterns 16 are formed on the Si3N4 film 12 with a gap l between the patterns. The gap l is so fine as to be about 0.2-0.3mum wide, however, this is because the gap width is narrowed by the value which is the expansion thickness of the oxidized film when converted thereinto.

Title: Method and apparatus for uniformizing work

IPC: H01L21/3065
Filed: 1990-02-21
Abstract: PURPOSE:To uniformize working speed on a sample by providing a microwave diffusion means at the joint with a microwave guide connected to the ionization chamber and by uniformizing the speed of ion beams flowing from the ionization chamber. CONSTITUTION:A gas introduced as diluted into an ionization chamber 2 is turned plasmatic by utilizing the electron cyclotron resonance due to the action of microwaves and magnetic fields, and generated ions flow out in an ion beam 10 by scattering magnetic fields impressed onto the chamber 2. The joint with a microwave guide 3 connected to the chamber 2 is provided with a concave lens 9 as the microwave diffusion means on top of a vacuum-sealing quartz glass 4 (lower end of a tube 3), whereby microwaves enter the chamber 2 as they remain diffused. This causes the density of plasma generated in the chamber 2 to be uniformized; therefore, ion beams 10 flowing out of this chamber attain a uniform density with the result that working speed on a sample 7 is uniformized to improve working uniformity.

Title: Lead frame with heat sink
Inventor: SHIMADA TOSHIYASU
IPC: H01L23/50
Filed: 1985-03-04
Abstract: PURPOSE:To absorb external force receiving in a manufacturing process by sections connecting adjacent heat sinks, and to prevent interface-peeling among a resin and the heat sinks by thinning he plate thickness of the sections connecting adjacent heat sinks. CONSTITUTION:A heat sink 1 is connected and fixed in a lead section 2 and caulking sections 1b. Even when such a lead frame is used and a resin seal is conducted, a warpage is generated. However, external force in subsequent manufacturing processes applied to the warpage generates deformation in thin sections 1a in the heat sink 1 because there are the thin sections 1a in the heat sink 1. Accordingly, the quantity of external force applied to the interface between a resin and the heat sink is reduced, thus generating no interface exfoliation.
