Title: Power converting device
Inventor: SEKINO YOSHIHIRO
IPC: H02M7/217
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a large-capacity but practical power converting device like an inverter device which enables the input and output of the device to be isolated, which is small-sized and light-weight and which does not deteriorate its controllability. SOLUTION: An AC input voltage from an AC power supply 3 is rectified with a single-phase diode rectifier circuit Rec via a high-frequency filter H.Fil and its output voltage Ein is controlled by a chopper converter 2 to be converted into a DC voltage Eout. The rectified DC voltage Ein inputted into the chopper is given to a reactor Lvia a pair of semiconductor switches Q1-Q2 and both ends are connected to an output side capacitor Cd via a pair of diodes D1-D2. By switching on and off a pair of the semiconductor switches Q1-Q2 simultaneously, the inputted DC power is converted to the output side. Because the period of time never exists when a pair of the semiconductor switches Q1-Q2 and a pair of the diodes D1-D2 are switched on simultaneously, the isolated state between the input and output sides is always maintained. Snubber circuit S is shown in broken lines.

Title: Wedge structure for car slide door
Inventor: NOUMI SHIGERU
IPC: E05F5/02
Filed: 1981-03-05
Abstract: PURPOSE:To prevent a body from damage by setting the spring constant to be large at a low load and small at a high load for promoting the shock-absorbing capacity. CONSTITUTION:A female 9 is made of synthetic resin or the like and provided with a fitting concave part 10 in its center. A male 12 is composed of a fitting body 14 fixed on a metallic base 13 and made of soft rubber or the like. The fitting body 14 is constructed of a triangular foot part 14a and a lip part 14b. In this construction, the spring constant against forward and backward loads is set to be small in the area of low load and large in the area of high load. Consequently, the shock-absorbing capacity is improved, and a body is prevented from the damage caused by the closing shock of a door. When they are fitted, the spring constant toward the left and right is increased to promote the sealing capacity and prevent vibration.

Patent JP-H10227670-A (JP)
Title: Gas flowmeter
Inventor: SAITO TOSHIHARU
IPC: G01F1/32
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To achieve a high-sensitivity measurement exceeding a threshold stably in a wide flow-rate measurement range by inverting either one first detection signal or the other second detection signal in inverse phase and synthesizing the both signals. SOLUTION: The output values of pressure sensors 2a and 2b are nearly equal values with opposite polarities. Then, output 4b of the pressure sensor 2b is inverted by an inverter 5 and becomes output 4b'. A synthetic signal 4c obtained by synthesizing both output 4a and 4b' becomes nearly two times larger than each output of the pressure sensors 2a and 2b, thus improving output drastically. In this manner, when detecting an eddy generated alternately at both sides of an eddy generator using two pressure sensors 2a and 2b being arranged in the eddy generator, output can be drastically improved and a flow rate can be measured more accurately by detecting the eddy with the pressure sensors at both sides.

Title: Trouble detecting safety device for fiber for laser transmission fiber
Inventor: DOI YUZURU
IPC: G02B6/42
Filed: 1986-02-17
Abstract: PURPOSE:To easily detect an accident on a fiber by detecting the stain, etc., of the tip part of the fiber from reflected light at the projection end surface for guide light, and detecting the breakage of a laser from secondary light generated at the breakage part and stopping irradiating laser light. CONSTITUTION:Power laser light 11a emitted by a power laser oscillator 11 impinges on an incidence end surface 16a from a laser intercepting device 12 through an optical path. At the same time, the guide light 17a from a laser oscillator 17 for the guide light is superposed upon the light 11a by a mixing mirror 13 and incident on the end surface 16a. The quantity of the reflected light of this light 17a is smaller than a constant level unless wastes stick on the surface of the end surface 16b. When wastes stick, on the other hand, the reflected light level drops, so the sticking of the wastes is detected by level detection. Further, if the fiber 16 is broken to generate the secondary light by fiber combustion, the quantity of light reaching a half-mirror 14 can be detected through a filter 18.

Title: Communication device with radio wave monitoring function
Inventor: SATO MASARU
IPC: H04B17/00
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To automatically discriminate plural different kinds of signals and to enable reception by being equipped with a means for enabling a user of its own station to monitor a radio wave emitted in a space by having the user of its own station listen to a communication signal, which is not a voice, that radio equipment has received. SOLUTION: A connection part 240 is added to a privacy telephone set 100. This connection part 240 connects a reception input signal to an output switching part 130. In this case, if a synchronization decision part 110 cannot decide that the reception input signal is not a secreted voice, a switching signal is transmitted so that a signal from the connection part 240 is outputted from the privacy telephone set 200. Thus, when the synchronization part 110 of the privacy telephone set 200 cannot decide the reception input signal to be the secreted voice, the reception input signal from the radio equipment is outputted to an output of the privacy telephone set 200 through the connection part 240 and it is to be heard from a speaker 30. Thus, a person can confirm that a radio wave 10 is being emitted to a space.

Title: Internal screw bottle plug for glass bottle
Inventor: UENAKA TETSUNOSUKE
IPC: B65D41/04
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain a bottle plug which is free from damage and has excellent sealing characteristics by fitting an inner plug made of synthetic resin formed on an inner peripheral face with a screw to be screwed with a screw formed on an outer peripheral face of a bottle mouth into a recess of an outer casing 7 which is entirely made of glass for integrating. SOLUTION: The bottle plug 3 comprises a cap-shaped inner plug 6 and an outer casing 7 covering the inner plug 6. The inner plug 6 is entirely molded of synthetic resin, while the casing 7 is entirely molded of glass. A screw 8 of the inner plug 6 of the bottle plug 3 is screwed with a screw 4 of a bottle mouth 2a of a bottle body 2, and the bottle plug 3 is put over the bottle mouth 2a to cover an outer peripheral face of the bottle mouth 2a. Glass is not in direct contact with glass in this state, but synthetic resin of the inner plug 6 is in contact with glass of the bottle mouth 2a. Since synthetic resin of the inner plug 6 aligns with a shape of an outer peripheral face of the bottle mouth 2a, tightness between an inner peripheral face of the bottle plug 3 and the outer peripheral face of the bottle mouth 2a is improved, thereby obtaining good sealing characteristics.

Title: Treatment method for metal mold surface
Inventor: ROKUTANDA HITOSHI
IPC: B24C1/10
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To improve a mechanical property of a metal mold surface by projecting a roughly spherical diametrical projecting material hardness of which is within a specific percentage range of Vickers hardness HV of a metal mold surface after heat treatment and a particulate diameter of which is a specific numerical range against the surface of the heat treated metal mold. SOLUTION: A roughly spherical diametrical projecting material hardness of which is 80-100% of Vickers hardness HV of a metal mold surface after heat treatment and a particulate diameter of which is 30-150μm is projected at speed 20-150m/s against the surfaces of a heat treated metal mold. Consequently, as surface roughness of the metal mold after peening treatment becomes less or equal to Ra 1.0μm, generation of scuffing is delayed. Additionally, when a method to project the roughly spherical diametrical projecting material the particulate diameter of which is 30-150μm at speed 20-150m/s is used, the maximum value of compression residual stress is formed on the metal mold surface.
