Title: Manufacture of flexible film
Inventor: ITO TATSUYA
IPC: B29C47/82
Filed: 1990-04-11
Abstract: PURPOSE:To make it possible to obtain highly transparent film, which is highly effected by cooling, by a method wherein flexible film, which is made of thermoplastic resin, is melt-extruded and coolingly cast through water film on a casting drum. CONSTITUTION:In the extrusion casting of flexible film, which is made of thermoplastic resin and has Young's modulus in tension of 0.1-50kg/mm<2>, the thermoplastic resin is melt-extruded in the form of sheet and coolingly cast through water film on a casting drum. Copolymer polyester where the temperature difference ( Tcg) between the cold crystallization temperature (Tcc) and the glass transition temperature (Tg) of the thermoplastic resin is 60 deg.C or less is preferable for the flexible film concerned. The preferable thickness of the water film is 0.05-20g/m<2>. Probably due to minute particles of water adhered to the film, which is cast through the water film, the degree of crystallization of the film tends to easily, increase by heat treatment, resulting in obtaining the film having high degree of transparency.

Title: Diamond coated tool
Inventor: KAWAI CHIHIRO
IPC: C04B37/02
Filed: 1990-04-16
Abstract: PURPOSE:To eliminate thermal cracks and provide combined antiwear property and break resisting property by composing a hard ceramic base of a soldered TiC part and SiC or Si3N4 interface between the base and a coating film to control the coefficient of thermal expansion in the direction of thickness. CONSTITUTION:In a tool having a hard ceramic base coated with diamonds, the base is composed of a TiC part soldered to metal and a SiC or Si3N4 interface between the base and a diamond coated film. The intermediate layer is composed of a composite layer of TiC and SiC or Si3N4 not to generate thermal cracks since the coefficient of thermal expansion does not rapidly change and the thermal stress is small. When the intermediate layer is composed of the TiC, SiC or Si3N4 having nearly continuously changing slope composition, the coefficient of thermal expansion nearly continuously changes so that the thermal stress further lowers to provide the coated tool excellent in a break resisting property.

Title: Car distance and speed measuring device
Inventor: KATAUE KOICHI
IPC: G01S13/34
Filed: 1992-04-17
Abstract: PURPOSE:To calculate the distance from the car concerned and its speed by transmitting to the car a frequency modulated wave generated based upon a triangular wave, receiving the wave reflected thereby to form a beat, and forming a rising and a sinking frequency signal from the beat frequency when the triangular wave is rising and sinking. CONSTITUTION:A triangular wave voltage generated by a triangular wave generator 5 is fed to a voltage control oscillator 4 to oscillate a frequency modulated wave. A directional coupler 3 gives part thereof to a mixer 6 and releases the rest from an antenna 1 via a circulator 2. The transmitted wave is reflected by a car to be measured, received by the antenna 1, passed to the mixer 6 via the circulator 2, and mixed with the transmitted wave to form a beat signal. The beat signal is converted into square wave by a zero-cross comparator 9 and supplied to counters 10, 11 to emit a sinking and a rising frequency signal when the triangular wave voltage is sinking and rising, respectively. An adder 13 adds the rising/sinking frequency signal and emits a signal corresponding to the distance, while a subtractor 12 subtracts the sinking/rising frequency signal and emits a signal corresponding to the speed.

Title: Controlling method for grinder
Inventor: TSUCHIYA SHOZO
IPC: B02C25/00
Filed: 1989-04-18
Abstract: PURPOSE:To control the rate of a raw material to be admixed with a final product in the outlet of a preceding grinder by automatically renewing the pressure of a hydraulic cylinder of the preceding grinder on the basis of the value of noise level of a trailing grinder or the value of electric power consumption of a transporting machine. CONSTITUTION:A raw material is sent to an intermediate bin 3 via a quantitative feeder 2 from a hopper 1. Then the raw material is introduced between the rolls of a roll mill 4 via an inlet chute, crushed and ground and thereafter discharged and supplied to a tube mill 5. The impulsive sound (noise) of both the grinding media, the rear plate of the drum body of the mill and a raw material is generated from the drum body of the tube mill and detected by a microphone 10. Further simultaneously the amount of the raw material discharged from the tube mill is detected by the power consumption of a motor 11 for a transporting machine 6. Thereby the loading state of the tube mill 5 is recognized and the proper oil pressure of a hydraulic cylinder 15 belonging to the roll mill 4 is calculated by a microcomputer 12 and regulated. When the oil pressure is raised, the rate of a final product admixed in the inlet of the tube mill 5 is increased and the load is lowered.

IPC: H01L21/60
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To make the surface of a land metal bonded to a solder ball maximal in area by a method wherein one or more etching holes are provided to the center or periphery of the land metal. SOLUTION: An etching hole 160 which is square, circular, or crossed is provided near the center of the surface of an SMD-type land metal 100. The etching hole 160 is formed through the land metal so as to reach to the surface of a BT board 360 or is formed as deep as half the thickness of the land metal 100, and then the etching hole 160 is successively plated with a nickel layer 110 and a gold layer 120. The surface of a solder ball 150 fused later to come into contact with the land metal 100 is enlarged in area by the etching hole 160. Furthermore, the etching hole 160 serve also as a locking hole which prevents the solder ball 15 from separating from the land metal 100 after the solder ball 150 is welded to the land metal 100. By this setup, a BGA semiconductor package where the solder ball is made to serve as an input/output terminal is enhanced in reliability.

Title: Fault section deciding method for power cable
Inventor: MATSUMURA TORU
IPC: G01R31/08
Filed: 1994-04-11
Abstract: PURPOSE:To decide a faulty section by detecting a fault current of a power cable through a CT, driving a solenoid with the output therefrom to bend an optical fiber, and then detecting the optical loss thud produced through an OTDR at the end of the optical fiber. CONSTITUTION:When a CT3 disposed at a joint of a power cable A detects a fault current of the power cable A, a solenoid 5 is operated with the output therefrom. Consequently, a stopper 6 is removed from a lower member 4b which is urged upward by means of a spring 7 and engages with an upper member 4a thus bending an optical fiber 1. Consequently, optical loss is generated in the fiber 1 and the generating position is detected at the fiber end 1 by means of an OTDR 2. Such detection mechanism is installed at each joint and the length of the optical fiber up to the installing position is previously measured. The joint of the cable, through which the fault current passed, is then determined with reference to the loss generating point. The fault point is located by tracking the fault current passing points.

Title: Tray, and packaging using the same
Inventor: OMORI SHOZO
IPC: B65D1/34
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a package wherein substitution of gas is performed reliably in a short time and a residual amount of oxygen in the package can be reduced. SOLUTION: An upper end rim 3a of a side wall 3 of a tray body 1 is made wavy (protruding and recessed). The tray body 1 with an object to be packaged received is surrounded by a packaging film 7, sealed and cut at predetermined positions to provide a pillow package. Before a rear end of the packaging film 7 in a proceeding direction is sealed and cut, degassing in the packaging film 7 is done and also inert gas is filled for gas substitution. Even if the packaging film comes into contact with the upper end rim of the side wall by the degassing at this time, a gap S is reserved whereby the inert gas can be supplied inside through the gap S. Thus gas substitution can be reliably done to suppress a residual amount of oxygen.
