Patent JP-H0388975-A (JP)
Title: Reciprocative compressor
Inventor: INABA KOICHI
IPC: F04B39/02
Filed: 1989-09-01
Abstract: PURPOSE:To prevent generation of undulate variation sound at 2500-5000Hz by furnishing a cylinder with a first-step chamfered part formed at the inlet for insertion of a piston and a second-step chamfered part in minor scale to the first step chamfer. CONSTITUTION:With rotation of a crank shaft 3, the oil passes through a hole 3a in the crank shaft 3, scatters from the top 3c of a crank shaft eccentric part 3b, runs against the wall surface 1a of a cylinder 1, creeps over the wall surface 1a, and reaches and stays in a first-step chambered part 1b of an angle 40-50deg. situated at a piston insert inlet of the cylinder 1. The oil stagnating there flows further to a second-step chamfered part 1c of an angle 10-30deg. owing to the capilary phenomenon, is held there, attached to the periphery 2a of the piston, and then a certain amount of this oil sufficient to exert the sealing effect intrudes into a gap between the periphery 2a of piston and the backmost part 1d in the cylinder due to the wetting effect at the time of the piston 2 in reciprocation. This prevents generation of undulate variation sound at 2500-5000Hz.

Filed: 1982-12-20
Abstract: PURPOSE:To constitute the titled cordless motor-operated calking gun with an extremely simplified system, by rotating a motor, transmitting the rotating motion with the combination of various gears, and moving a rack to extrude a calking agent. CONSTITUTION:By rotating a motor 3, said motor 3 is brought into contact with a transmission gear 5 under proper friction force. By the rotating power of a gear supporting plate 7 for holding a free gear 6, the free gear 6 engages the transmission gear 5 with a rack-moving gear 2, rotates the rack-moving gear 2 and moves a rack 1 to extrude a calking agent. By the same way, the motor is reversely rotated to retreat the rack 1. Thus, the cordless motor-operated calking gun which can be used at an optional site is obtained.

Title: Semiconductor laser device
Inventor: KASHIHARA MINORU
IPC: H01L23/40
Filed: 1993-09-10
Abstract: PURPOSE:To reduce a rejection rate in a junction process by forming a recessed part which is wider than an electrode of a semiconductor laser device and narrower than the semiconductor laser device in a heat sink for the semiconductor laser and fitting the electrode of the semiconductor device into this recessed part. CONSTITUTION:A solder layer 10c formed on a recessed part 10a of a semiconductor laser heat sink 10 is arranged to push an electrode 20d into the recessed part 10a in a molten state. As the recessed part 10a is wider than the electrode 20d and narrower than a semiconductor laser device 20, only the electrode 20d, which is placed into contact with a junction surface 10d of the semiconductor laser device 20, is pushed into the solder layer 10c, which practically prevents the solder layer 10c from being built up. This construction eliminates such harmful effects as obstructions to a light emitting unit 20a of the semiconductor laser device or a short circuit to an active layer 20b, thereby lowering a rejection rate in these junction processes.

Title: Automatic frequency controller for power generating device
Inventor: MARUYAMA YUKIHIRO
IPC: H02P9/00
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To prevent large imbalance of a load to each individual generator with a power frequency of generating bus kept constant. SOLUTION: Each of load detection means 2-1, 2-2, 2-3,... detects each load of generators G-1, G-2, G-3,..., while each of pulse passage control means 3-1, 3-2, 3-3,... can block a command pulse (i.e., a governor increasing command pules or a governor decreasing command pulse) to each of the generators G-1, G-2, G-3,.... When each of the generators G-1, G-2, G-3,... is operated under an appropriate load, the governor increasing command pulse or the governor decreasing command pulse from a governor controller 1 is output to each of the governors C-1, C-2, C-3,... so that an instantaneous frequency of a generating bus B is corrected to be an appropriate value. Otherwise, when an overload or a low-load in a certain generator (e.g.  G-1) is detected by the corresponding load detection means (i.e., 2-1), the corresponding pulse passage control means (i.e., 3-1) blocks the command pulse to that generator G-1 so as to prevent a further overload or a further low-load of that generator G-1.

Title: Frictional energy analyzing method for rolling tire
Inventor: SUMIYA YOSHIRO
IPC: G01M17/02
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To easily analyze frictional energy by measuring the in-plane pressure and vertical pressure at one point of a tread by the rolling of a tire, determining static frictional force, and determining the frictional energy in a sliding region having a value larger than the primary maximum value of this static frictional force. SOLUTION: The in-plane pressure, vertical pressure, and slip quantity for the ground length L of one point of a tire are measured and calculated, and static frictional force R(L) is determined based on the obtained in-plane pressure and vertical pressure. The primary maximum value Rm of the static frictional force R(L) is determined afterwords. This Rm is a value nearest to a ground front end section A in the primary maximum value. A ground position exceeding the maximum static frictional force Rm is a limit value C, the ground range LR to a ground rear end section B thereafter becomes a sliding region where frictional energy occurs. The sum total of the work is determined by integration in the whole sliding region LR, and frictional energy can be determined by multiplying the sum total by the prescribed proportional constant.

IPC: F01D21/00
Filed: 1988-09-09
Abstract: PURPOSE:To simply and positively prevent rust and preserve steam turbines by providing temperature detectors at typical portions of turbine casings, and automatically injecting dry air into the casings when it is detected that the temperature at the portions reaches a specified value. CONSTITUTION:Temperature detectors 21, 22 are provided in a high pressure casing 1 and a low pressure casing 2 respectively, and air injection valves 25, 26 are provided to injection pipes 11, 12. When steam turbines are stopped, both high pressure and low pressure turbines are cooled off with time, and the temperature of the low pressure turbine first reaches a satulation temperature. When the turbine is cooled off below the satulation temperature, dew-drops are generated on the surface of the turbine and can cause the generation of rust. Thus, when a typical portion of the low pressure turbine reaches a specified temperature, an air injection valve 26 is adapted to be opened based on a signal from the temperature detector 22 to inject dry air into the low pressure turbine casing 2 so that the casing can be held at dried state. In the same manner, dry air is injected into the high pressure turbine casing 1.
