Patent JP-S57170617-A (JP)
Title: Receiver
Inventor: ISHII HIDEKAZU
IPC: H03J7/18
Filed: 1981-04-13
Abstract: PURPOSE:To increase an automatic sweep speed, to eliminate the malfunction of automatic sweeping, and to reduce the cost of constitution by increasing the sweep speed of a reception frequency by an automatic sweeping mechanism when a received signal level is low, and decreasing it when high. CONSTITUTION:A signal intensity detecting circuit 11 detects the signal intensity of a limiter amplifying circuit 6 and then sends it to a discriminating circuit 10. When it is judged that an input has not enough signal intensity, the output of a low-frequency amplifying circuit 8 is muted to prevent it from appearing at an output terminal 9. On the other hand, the outputs of the detecting circuit 11 and discriminating circuit 10 are inputted to an automatic sweeping circuit 14. When the signal level does not reach a certain level yet, the sweep speed of the tuning frequency of an FM receiver by an automatic sweeping circuit 14 is increased and when so, the speed is decreased.

Title: Manufacture of semiconductor device
Inventor: NISHIDA SOICHI
IPC: H01L21/768
Filed: 1990-03-07
Abstract: PURPOSE:To make the thickness of the uppermost layer of a multilayer metal interconnection thin for increasing an ability to meet customers' requirements for an ASIC (high density integrated circuit) by using a high melting point metal film for the uppermost layer of the multilayer metal interconnection. CONSTITUTION:A metal interconnection 3 is formed on an insulating film 2 formed on a semiconductor substrate 1. Then, a layer-to-layer film 4 is accumulated to make the surface flat, making a through hole 5. Nextly, high melting- point metal material 6 is deposited in the thickness of 0.4mum by a sputtering method to conduct a patterning of a second metal interconnection. At this time, a thick photo-resist film is usually required since there is a large difference in level. By this method, however, there is no need for the thick photo-resist film since the high melting-point metal interconnection material 6 which is to be etched is thin. Consequently, a fine patterning is available. Last of all, a protection film 7 is accumulated.

IPC: C23F4/04
Filed: 1984-03-23
Abstract: PURPOSE:To improve the selectivity ratio of etching rates and to enable SiO2 to have a vertical cross section when dry etching the same, by disposing the SiO2 in the atmosphere of inactive gas or in a vacuum and irradiating the same with a CO2 laser beam and ion beams. CONSTITUTION:A material 21 of Si, SiO2 and the like is disposed within a vacuum device 20 into which chlorine or fluorine gas 23 is introduced through a gas inlet tube 22, while a laser beam 25 from a CO2 laser 24 arranged outside the device 20 is applied with low acceleration energy obliquely onto the material 21 via a rotary reflecting mirror 210 and a window 26. In such a manner, the SiO2, which is excited by the activated etchant 27, can be easily etched vertically. On the other hand, the lattice vibration of the Si is not affected by the beam and therefore it is not etched. Ion beams 29 from an ion source 28 arranged outside the device 20 are then applied onto the Si of the material 21 so as to etch the Si with molecules of chlorine or fluorine.

An aimed value of thickness corresponding to each cycle point set at every n-section time of a molding cycle time is calculated from this pattern. Then, a stroke of a core is calculated from this aimed value of the thickness and a hydraulic cylinder is controlled by using a signal output at each cycle point and the core is moved so as to obtain a given stroke.

Filed: 1982-04-06
Abstract: A process and apparatus for coating the interior of a fiber-reinforced tube formed of cellulose hydrate in which a tube filled with a coating liquid is passed through a special conveying and pumping device which also serves to replenish the coating liquid. Above the level of the coating liquid, the tube is inflated with a support gas and is gradually flattened. The flattened tube then travels through a metering device made up of wipers in the form of doctor blades or rollers, which retain the major quantity of the coating liquid which is present on the inside surface of the tubing so that a thin, uniform film of the coating liquid is formed. The tubing is thereafter dried to remove the volatile constituents of the coating liquid, and is subsequently wound up.
