Title: Closed type motor-driven compressor
Inventor: SAKAI MASATOSHI
IPC: F04B39/12
Filed: 1990-09-20
Abstract: PURPOSE:To restrain temperature rise in the interior of a compressor, and to heighten the degree of freedom in the arrangement of a cooling piping by supplying lubricating oil to respective sliding surfaces by means of a forced-feed oiling mechanism, and by communicating one end of an oil conveying and cooling pipe on the outside of a vessel with the sliding surfaces, and the other end thereof with the inside of the vessel respectively. CONSTITUTION:When a driving shaft is driven by an electric-motor element 6 to operate a forced-feed oiling mechanism 21, the lubricating oil in an oil reservoir 15 is sucked through an oiling hole 22, and passing through an oil hole 11 and horizontal holes 12, 13, it is supplied to respective bearing sliding parts. A part of the lubricating oil, after passing through respec tive sliding parts, returns to the oil reservoir 15, while most of the lubricating oil discharged from the forced-feed oiling mechanism 21 stays in a discharge-oil recess 23, and then passing through a discharge oil hole 24, it is discharged to the outside of a vessel 1. While passing through an oil conveying and cooling pipe 16, the discharged lubricating oil is cooled by the action of heat radiation due to natural and forced convection in the inside and outside of the oil conveying and cooling pipe 16. And the cooled lubricating oil is returned to the electric-motor element 6 side in the inside of the vessel 1 through the oil conveying and cooling pipe 16. Thus, by this cooled lubricating oil, the main heat generating part such as the elecrtric-motor element 6 can be cooled.

Title: Two-way functional parts and opening/closing gear for ventilating hole therewith
Inventor: KAWAMURA ATSUSHI
IPC: G03G21/20
Filed: 1993-10-07
Abstract: PURPOSE:To provide functional parts which are simple in their construction and available for multistage control at a low cost. CONSTITUTION:A bias spring 3 is inserted into one side of an axis 5 to which a circular plate 6 is fixed. Shape memory alloy springs 1, 2 having transformation points T1, T2 (T1<T2), respectively, are inserted into the opposite side of the axis 5 across the circular plate 6. While springs are arranged to push each other, the axis 5 is inserted into a case 4 so as to be retained freely slidably. When the atmospheric temperature of the functional parts 10 becomes less than T1, the bias spring 3 pushes the circular plate 6 so that the shape memory alloy springs 1, 2 are shrunk and the axis 5 is placed in the lowermost position (initial position). When the temperature rises and exceeds T1, the shape memory alloy spring 1 stretches and upwardly pushes the circular plate 6 so that the axis 5 may be displaced at an intermediate position. When the temperature further exceeds T2, the shape memory alloy spring 2 stretches more and upwardly pushes more the circular plate 6 so that the axis 5 may be displaced in the uppermost position (final position). When the temperature falls, the axis is displaced in the reverse direction from the intermediate position to the initial position.

Title: Parts supply head
Inventor: IWABUCHI MASAKI
IPC: B65G51/02
Filed: 1987-10-07
Abstract: PURPOSE:To make an accurate parts positioning by making an compressed air in which pressure is uniformed to flow from the peripheral wall to the inside of a supply tube in which parts are gravitationally dropped in a supply head of a small screw, etc. CONSTITUTION:A small screw 12 is gravitationally dropped in the inside of a supply tube 11. A compressed air uniformly flows into the tube 11 from inflow holes 21 after the compressed air is supplied in a ring-state chamber 15 from an unshown compressed air supply source and pressure is made uniform. And the compressed air has a high pressure in the peripheral part near the holes 21 and a low pressure in the middle part. Accordingly, the dropping small screw 12 is guided to the middle of the tube 11, and its attitude is corrected in the axis direction of the tube 11 by the pressure difference. Consequently, a gap is formed between the screw 12 and the inner periphery, and the screw 12 has an accurate attitude and position. Thus an accurate positioning can be obtained.

Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide the EGR construction that restrains stress concentration of welding part of EGR pipe. SOLUTION: This structure forms U-shaped bent part 10, nearly U-shaped (180 deg. bent) at connecting part of both ends of pipe 7c of EGR pipe.

U-shaped bent part 10 is placed at both ends of pipe 7c so as to curtail rigidity. Due to bending of part 10, stress given rise to at welding parts 8, 9 is restrained, and the strength of the welding parts 8, 9 is relatively increased. Thus, current quality of EGR pipe holds good with coming exhaust gas regulations.

Title: Heater lamp
Inventor: IKEDA TOSHIHARU
IPC: H01K1/32
Filed: 1989-09-29
Abstract: PURPOSE:To prevent a heater lamp from glaring at a time of lighting even when looked at directly by coating the surface of a sealed tube made of quartz glass with a multilayered light interfering film and making specific amount of luminous flux to be reflected to the inside of the sealed body owing to the multilayered light interfering film. CONSTITUTION:The outer surface of a sealed tube 1 is coated with a multilayered light interfering film 7 having characteristics to reflect mainly visible light and transmits infrared ray. At least 50% luminous flux is reflected to the inside of the sealed tube 1 by the multilayered light interfering film 7. Like this, since at least 50% of luminous flux is reflected to the inside of the sealed tube 1 by the multilayered light interfering film 7, visible light with wavelength about 557nm to which human being's eye has high sensitivity is reflected to the inside of the sealed tube 1 and scarcely reflected to outside. In this way, even when looked at the time of lighting, the heater lamp does not glare.

Title: Number of revolution detection mechanism for surface wave motor
Inventor: HASUDA MASANORI
IPC: G01D5/245
Filed: 1986-10-24
Abstract: PURPOSE:To detect the number of revolution of a surface wave motor with high accuracy by compact constitution by providing a speed increasing means which is arranged between the surface wave motor and a pulse signal generating means, and accelerates and transmits the rotation of the surface wave motor to the pulse signal generating means. CONSTITUTION:A signal indicating the end of exposure is transmitted to a driving control circuit 14, which powers on the piezoelectric element 3 of the surface wave motor, so that its rotor 2 begins to rotate as shown by an arrow U. The rotating speed of the rotor 2 is increased by the speed increasing mechanism G1 and its rotation is transmitted to a pulse generation plate 4; and a pulse signal, i.e. electric pulse signal is generated by the rotation of the pulse generation plate 4 and applied to a terminal 15 and the signal is sent to the driving control circuit 14. The rotating speed of the rotor 2 is increased, so shorter pulse intervals are obtained in consideration of the number of pulses generated in every turn of the rotor 2. Thus, the numbers of revolution of the rotor 2 is detected with high accuracy without increasing the diameter of the pulse generation plate 4.
