Title: Tunnel penetrating construction method to underwater
Inventor: KITAMURA NORITAROU
IPC: E21D9/06
Filed: 1995-01-13
Abstract: PURPOSE: To provide a tunnel penetrating construction method to underwater by which water can be reliably stopped and construction work can be safely performed in a short time and construction work cost is reduced and which is suitable for the protection of a natural environment when a tunnel is penetrated to underwater. CONSTITUTION: A departing shaft 20 is constructed in a shielding departing position. Shielding excavation is propelled up to a position close to a beach line T from the departing shaft 20 while assembling a segment 26. While connecting a propelling pipe 30 to a tail part 28 of a shielding machine 24 in the segment 26 in a position close to the beach line T, the propelling pipe 30 is propelled by a propelling jack 34 arranged in the segment 26, and the shielding machine 24 is made to reach underwater. Water is stopped by installing a sealing cover on the propelling pipe 30 in an underwater reaching position. After the propelling pipe 30 is sealed by the sealing cover, the shielding machine 24 is separated from the propelling pipe 30, and is taken out from underwater. After the shielding machine 30 is taken out, the sealing cover of the propelling pipe 30 is removed from underwater.

Title: Calculation of pwm waveform in inverter control
Inventor: OKA TAKAAKI
IPC: H02P27/08
Filed: 1989-01-31
Abstract: PURPOSE:To prevent distortion of motor current waveform even when the control rate exceeds 1 by employing distorted three-phase sinusoidal waves, then superposing the three-phase distorted waves over a carrier wave, and calculating a PWM waveform data. CONSTITUTION:A U-phase voltage waveform (pulse train) at a time point is obtained by superposing the U-phase of distorted wave 3 over the carrier wave 2. When the wave superposed on the carrier 2 is a sinusoidal wave 1a under the condition that the control rate exceeds 1, these are produced pulses in the ranges Ua, Ub corresponding to the pulses Pa, Pb, Pc and Pd, Pe, Pf of the U-phase voltage waveform (pulse train). In other words, the number of pulses in the pulse train of the U-phase voltage waveform do not decrease but is the same as the number of pulses when the control rate is lower than 1. Pulses are produced similarly in the ranges Va, Vb of V-phase voltage waveform and in the ranges Wa, Wb of W-phase voltage waveform. Consequently, distortion of current waveform of three-phase motor is suppressed similarly to the case where the control rate is lower than 1.

Title: Ornamental arm ring with display device
Inventor: ICHIKAWA SHINGO
IPC: G04B37/16
Filed: 1984-02-08
Abstract: PURPOSE:To obtain an ornamental arm ring provided with geometrical beauty in addition to the functional characteristic display by packaging an electronic circuit and display device to the ornamental arm ring. CONSTITUTION:An upper leaf spring 5 is welded to at spring holding part 3b and a lower leaf spring 6 is welded and fixed to the surface 4a of a rear cover 4. A module 2 is housed in an insulation-coated module housing part 3a of a base body 3. A rear cap 4 is attached thereto by means of a screw 10. A deformable body 7 is inserted between the springs 5 and 6 and the top end 7a is engaged with the lower part in the spring part 3c of the body 3. A resin tube 8 is put on a module 2 in such a way that a transmission window 8a is positioned on the display surface 2a of the module. The central part of the base body 3 acts consequently as a rigid structure to protect the module 2 but the spring part 3c of the body 3 is tapered toward the outside and therefore said part has the gradually inceasing elasticity. The deformable part by the body 7 consisting of lead, etc. and the springs 5, 6 is formed from the part where the spring part 7c ends. Therefore if an ornamental arm ring 1 is curved and deformed, the spring part 3c curves gradually while the part of a transparent window 8a is deformed. The deformation thereof is transmitted to the deformable part by which the arm ring is mounted to the wrist.

Title: Control method for supercharger with varying nozzle
Inventor: SASAKI SHOJI
IPC: F02B37/24
Filed: 1986-02-05
Abstract: PURPOSE:To prevent over-increase of an engine back pressure due to over- closing of a nozzle in a low speed region, by a method wherein the engine back pressure on the turbine side of a supercharger and a boost pressure on the compressor side produces parameter of control of the opening of a nozzle. CONSTITUTION:A controller 12 sets a throat width (d) of a nozzle 2 to a minimum position in an engine low speed region. Since, when, with this state, the number N of revolutions of an engine is increased, it enters the compressor surge region of a supercharger and operation is stabilized, and the width (d) is increased. But, since, in return control in that a boost pressure P3 is controlled to a set value, operation is unstabilized due to a delay in response, a nozzle position is controlled by means of the number N of revolutions. In control of the opening of the nozzle 2, by means of a differential pressure between the boost pressure P3 and an engine back pressure P4 or a ratio therebetween, valves A-D are opened and closed to effect switching between a feed passage for oil and a return, and a cylinder 8 of an actuator 6 is driven to control the opening of a nozzle. This constitution prevents over-closing of the nozzle in a low speed region, and produces a sufficient supercharging effect.

Abstract: PROBLEM TO BE SOLVED: To eliminate necessity of fine adjustment of height of a stamping blade and prevent marring by the stamping blade by constituting a face plate of a hard layer to directly make contact with the stamping blade and an elastic layer positioned in a lower layer of the hard layer. SOLUTION: It has a two-layer structure of a hard layer 1 and an elastic layer 2, and a sheet material placed on an upper surface 1a of the hard layer 1 is stamped by a stamping blade. The hard layer 1 is desirably made of metal lower in hardness than the blade to keep sharpness of the blade for a long time. The elastic layer 2 is positioned in a lower layer of the hard layer 1 and absorbs pressure force of the blade. It is possible to make one layer or to make a laminated structure of not less than two layers, and its material is desirable to be plastic, rubber, plywood, etc. As there is no clearance existing between the stamping blade and the hard layer 1 by providing this elastic layer 2, the sheet material is completely stamped.
