Title: One-way cluth device
Inventor: IGA KAZUO
IPC: F16D41/06
Filed: 1993-09-01
Abstract: PURPOSE:To actuate torque in the free direction of a clutch heavily with a simple structure by installing a coil spring acting in the tightly winding direction between a rotary shaft and an annular shaft directional extending part formed in one end part of a housing. CONSTITUTION:A shaft 2 is inserted in a housing 1 whose tooth part is formed on the outer periphery, and a clutch part 3 is arranged in the circumferential space. A coil spring 14 whose rewind direction becomes the free direction of a clutch is installed between a shaft directional extending part 11 of the housing 1 and the shaft 2, and one end part 15 of the spring 14 is inserted in and fixed to one of shaft directional grooves 12 formed in the shaft directional extending part 11. When the shaft 2 rotates in the lock direction of the clutch, the shaft 2 is locked on the housing 1, and the coil spring 14 coming into contact with the shaft 2 rotates the shaft 2 in the tightly winding direction. To the contrary, when the shaft 2 rotates in the free direction of the clutch, frictional force by fastening force of the coil spring acts as resistance when the coil spring 14 is rewound. Thereby, torque can be increased when the clutch is transferred to a free condition.

Title: Optical hydrophone
Inventor: MURAKAMI TAISUKE
IPC: G01H9/00
Filed: 1983-12-20
Abstract: PURPOSE:To eliminate fluctuation in output by utilizing the Fresnel-reflected light at the incident end of an optical fiber for measurement as reference light. CONSTITUTION:The light beam emitted from a laser 40 passes through a half mirror 46 and is partly Fresnel-reflected by the incident end face of an optical fiber 42. The balance is mostly made incident to the fiber 42. The light incident to the fiber 42 is reflected by the total reflecting mirror 52 at the exit end face of the fiber 42 and returns to the incident end. The light beam propagating in the fiber 42 during this time is subjected to a phase modulation by the underwater sound field and interferes with the light Fresnel-reflected at the incident end of the optical fiber. Said light is then made incident to a photodetector 48 by the half mirror 46. The acoustic signal outputted from the photodetector 48 by such homodyne detection wave is inputted to a signal processor by which the waveform is displayed or the spectrum is displayed.

Title: High pressure sodium lamp
Inventor: WATANABE MITSUAKI
IPC: H01J61/36
Filed: 1984-11-15
Abstract: PURPOSE:To reduce the size of a high pressure sodium lamp by inserting supporters having an almost rectangular cross section into cylindrical parts installed at the ends of the luminous tube and connecting lead wires to the supporters. CONSTITUTION:Metallic supports 7 and 8 having an almost rectangular cross section are inserted into cylindrical parts 5 and 6 installed at the ends of a luminous tube 4 thereby connecting the cylindrical pats 5 and 6 to the supporters 7 and 8 respectively. The luminous tube 4 is held in an outer tube 1 by connecting lead wires 9 and 10 to the supporters 7 and 8 respectively. Because of the above structure, the outer diameter of the outer tube 1 may be small. Adequate vibration resistance and shock resistance of the lamp can be achieved by using a wire with a large diameter as the lead wire 10 even when a thin wire is used as the lead wire 9 in order to produce necessary electric capacity. Therefore, the size of the lamp can be reduced.

Title: Method for growing crystal on circular wafer
Inventor: NAKAJIMA YASUO
IPC: H01L21/02
Filed: 1991-08-27
Abstract: PURPOSE:To make the producing processes of waveguides and electrodes easy and accurate to practice maintaining a circular wafer unchanged by carrying out a crystal growth while a cleavage orientation flat portion is protected by a protective coat. CONSTITUTION:A plurality of circular wafers 10 in a bear wafer state are piled up and set in alignment with the cleavage surface of a cleavage orientation flat 11. An SiO2 film having an thickness of several hundreds to several thousands is formed as a protective film 13 along the orientation flat 11 by electron beam deposition techniques while a plurality of the circular wafers 10 thus stacked are set upright or obliquely. A p-n junction is formed by producing an epitaxially grown layer 12 on the wafer 10. Along the orientation flat 11 the presence of the SiO2 film 13 prevents the crystal growth. Therefore, when the SiO2 film 13 is removed, there is obtained a crystal grown wafer with the epitaxial layer 12 while the areas adjacent to the orientation flat 11 remain as they were before the crystal growth.

Title: Vacuum switch
Inventor: ITO MASAYOSHI
IPC: H01H33/66
Filed: 1988-09-27
Abstract: PURPOSE:To obtain a device being compact and having smooth switching operation by directly making a busing a case of a vacuum bulb while providing a bellows on the peripheral part of a movable electrode and a sealed material on the peripheral part of a contact of the electrode. CONSTITUTION:In a closed state of a vacuum switch, a fixed electrode 4 and a movable electrode 11 inside an opening recessed part 3e are closed while a current flows from the electrode 4 to the electrode 11. When the electrode 11 moves to the side of an inner edge, a bellows 13, which is fixed to the electrode 11, shrinks to the side of the inner edge to hold a vacuum inside a bushing. At the time when the electrode 11 separates from the electrode 4, metal vapor due to an arc generates between the contact part 4C and 11a but a sealed material 12 prevents vapor from being scattered. In this way, since the bushing 3 forms a vacuum bulb directly, the whole of the vacuum switch can be made compact. Moreover, switching operation can be smoothly performed, since the bellows 13 is provided on the peripheral part of the movable electrode 13 and the sealed material 12 is provided on the peripheral part of both contact parts 4C and 11a.
