Title: Surface hardening method for cast iron parts
Inventor: FUKUHARA YOSHIKAZU
IPC: C21D7/06
Filed: 1986-04-25
Abstract: PURPOSE:To harden the optional surface of a part by shot-peening the surface of the cast iron parts having an austenitic structure while keeping the surface at a low temp., heating the parts in a specified temp. range, air-cooling the parts, and then age-hardening the parts. CONSTITUTION:Air and iron balls are injected at high speed in a shot peening device 3 to treat the surface of the cast iron parts, 1 having an austenitic structure, and a low-temp. solvent (liquefied nitrogen, etc.) is sprayed along with the iron balls and air current from a low-temp. solvent tank 4 connected to the device 3. Consequently, the material in the vicinity of the surface 2 to be treated is transformed from austenite to ausformed martensite. The surface 2 to be treated is then heated to 300-600 deg.C by a dryer 5 or an electric furnace, and then air-cooled. The material of the surface 2 to be treated is tempered by this age hardening from martensite to (martensite+carbide), and the hardness can be controlled to >=about 500Hv.

Filed: 1995-04-20
Abstract: PURPOSE: To obtain the compact radiation sensor having the excellent performance by providing thick thermistor film layers, on which electrodes are formed, on both sides of a ceramics-sintered body layer. CONSTITUTION: A radiation sensor 10 has a ceramics sintered body layer 11, and two layers of thick thermistor film layers 12 and 13 holding the ceramic sintered-body layer.

Title: Torsional-vibration detecting apparatus for rotary body
Inventor: KONO TAKASHI
IPC: G01H1/10
Filed: 1989-04-17
Abstract: PURPOSE:To detect the high-order torsional vibration of a rotary body by providing a medium disk to be detected having radial protruding parts from the rotary center, and optical detector, an amplifier and a demodulator. CONSTITUTION:The amount of light which is inputted on a medium disk to be detected 5 is changed based on the presence or absence of the protruding parts of a reflecting surface. When the height of the protruding part is made to be about 1/4 of the wavelength of the incident light, the light which is reflected from the tip of the protruding part is deviated by the 1/2 wavelength and 180 deg. in phase in comparison with the light reflected from the flat surface at the surrounding part. When the deviated light and the normal light reflected from the flat surface are interfered, the amount of the reflected light is decreased. The output value of a photodiode is changed based on the presence or absence of the protruding part 6. When torsional vibration occurs, the amplitude corresponds to the density of pulses, and the frequency corresponds to the repeating period of the density. Therefore, the torsional vibration component can be detected by performing FM demodulation of said signal.

Title: Semi-automatic door
Inventor: MUKAIDE TAKAHIDE
IPC: E05F5/06
Filed: 1997-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent rebound and a pulsation phenomenon by bringing a roller of a sash pulley into pressure contact with a guide plate of a slowingdown stopper fitted along an upper rail. SOLUTION: A door 1 is fitted with a sash pulley 3 and hangingly provided on a slightly inclined upper rail 2, and the door 1 is automatically closed by the action of own weight. A slowing-down stopper 6 is fitted along an upper rail 2. The slowing-down stopper 6 is composed of a guide plate 7 and a foam body 8, and oblong holes 9, 9 are provided with threads 10, 10 so as to make the slowing-down stopper 6 vertically movable. In case of opening the door 1, the door 1 moves, and a roller 5 of the sash pulley 3 comes in contact with the slowingdown stopper 6. At this time, one end of the guide plate 7 is bent upward to facilitate the entry of the roller 5 of the sash pulley 3, and the guide plate 7 is pushed up by the roller 5 so as to ascend while compressing the foam body 8. The rotation of the roller 5 is thereby suppressed, and braking action is generated. Accordingly, even when the door pushed open by hand travels at high speed, the door is slowed down by the slowing-down stopper, and the door does not rebound in contact with the stopper.
