Title: Molding type package for high frequency
Inventor: INOUE AKIRA
IPC: H01L23/12
Filed: 1988-02-08
Abstract: PURPOSE:To drive a semiconductor chip by desired high-frequency performance characteristics by conforming the characteristic impedance of distributed constant lines composed among exposed lead sections and the characteristic impedance of distributed constant lines constituted among lead sections not exposed. CONSTITUTION:At least one of the width of leads 4 for signals and the mutual spaces of the leads 4 for the signals and leads 6 for grounding is set so that the characteristic impedance of distributed constant lines constructed of each exposed lead section 4a, 6a of the leads 4 for the signals and the leads 6 for grounding and the characteristic impedance of distributed constant lines constructed of each lead section 4b, 6b not exposed of the leads 4 for the signals and the leads 6 for grounding coincide. Consequently, the unnecessary reflection of high-frequency signals is not generated on the boundary sections of the exposed lead sections 4a, 6a and the lead sections 4b, 6b not exposed. Accordingly, a semiconductor chip packaged into a resin molding section can acquire desired high-frequency characteristics to the high-frequency signals.

Abstract: PROBLEM TO BE SOLVED: To reduce torque and torque fluctuation, and improve a cleanliness of a bearing, by carrying out a vacuum drying of diluted oil and forming a coating or thin film to at least a raceway surface and a sliding surface of a bearing surface. SOLUTION: Fluorocarbon oil having high affinity is used as a lubricating oil 15. In sealing method, before ball bearings 11 and 12 are incorporated to a shaft 1 and a housing 10, the lubricating oil 15 which is previously diluted (10 to 200 times) with a substitutive fluorocarbon is injected to raceway surfaces 13, 14, which are subjected to vacuum drying (100 deg.C for 2 hours) to form a coating or a thin film. Accordingly, considerably minimum lubricating oil can be injected easily. Further, by initial rotations or oscillations of the bearings 11, 12, the lubricating oil 15 is transferred to the raceway surfaces 13, 14 which are contact surfaces with balls 3, 5, respectively, and is transferred to sliding surfaces 16, 17 which are contact surfaces between the balls 3, 5 and retainers 18, 19 in pocket surfaces. A sealing amount is 0.3 to 3%; of a space volume inside the bearing.  Accordingly, evaporation and splashing of the lubricant are reduced, and torque and its fluctuation can be reduced.

IPC: G03C1/30
Filed: 1984-02-16
Abstract: PURPOSE:To provide a gelatin hardening method having a rapid and proper hardening action, and preventing fog without raising viscosity of a coating fluid before coating by hardening gelatin in a silver halide photosensitive material specified in pH of a film with an N-methylol type hardening agent. CONSTITUTION:Gelatin in a silver halide photosensitive material having a film pH of 3.0-4.8 is hardened with an N-methylol type hardening agent. Such a photosensitive material, a silver salt diffusion transfer photosensitive material contg. a developing agent is preferable, and as the N-methylol type hardening agent, an oligomer can be used like a monomer. It has a rapid and adequate hardening action in a film pH of 3.0-4.8. A photographic material hardened with this compd. does not deteriorate photographic characteristics and the transfer density of the DTR method during long term storage. Since it does not raise the viscosity of a gelatin compsn., the coating operation is made easy. Accordingly, it can be used for a silver halide photosensitive material contg. a silver halide emulsion and a developing agent, and widely used for other materials.

Title: Longitudinal cutting method of slab and device thereof
Inventor: OSADA SHIYUUJI
IPC: B22D11/126
Filed: 1979-03-12
Abstract: PURPOSE: To cut slab and improve productivity by generating shearing force in the rolling groove after rolling at subsequently smaller angles of the rolling groove within a limited range along with the progression of rolling pass.  
     CONSTITUTION: The slab of a high temperature is rolled by the upper and lower rolls provided with an annular protrusion in the roll barrel part. At this time, a rolling groove is formed in the slab by making the taper angles α 1-3  of the annular protrusion subsequently smaller within a range from 20 to 120° along with the progression of the pass and rounding the corner 2 of the flat part 1 of the end of the protrusion or subsequently rolling the slab two or more times by the beveled roller protrusion. Next, the forces in the directions mutually opposite to the rolling groove bottom t 3  of the slab are acted by the upper and lower rolls to cut the slab. The limitation of the taper angles of the protrusion and the avoidance of sharpness through provision of a flat part to the end prevent fracture and failure owing to thermal stress and improve the slab side edge shape.

Title: Voice level comparison system of hand free telephone set
Inventor: NAGAI NORIO
IPC: H04M1/60
Filed: 1984-02-17
Abstract: PURPOSE:To reduce malfunction of a voice switching circuit due to noise by providing a filter to the pre-stage of a level comparison circuit limit the frequency range of a voice input to the level comparison circuit thereby decreasing effectively the input level of a background noise inputted to the level comparison circuit. CONSTITUTION:While a receiving voice exists on a reception line and the transmission line is at a lower level than the received voice, since the output signal of the level detecting circuit 4 is larger than the output signal level of the level detection circuit 3, the level comparison circuit 5 keeps the output signal of positive level, the state of a switch circuit 6 turned off and switch circuit 7 turned on is continued and the reception state is continued. When the transmission voice is inputted from a microphone MC is inputted and an output signal level of the level detection circuit 3 is higher than the output signal level of the level detection circuit 4, the level comparison circuit 5 inverts the polarity of the output, the switch circuit changes from OFF to ON and the switch circuit 7 changes from ON to OFF and the transmission state is attained. As filters 1, 2, a high pass filter, a low pass filter or a band pass filter is used depending on the environment where the telephone set is located to cut off effectively noise.
