Title: Production of glass preform for optical fiber
Inventor: ISHIKAWA SHINJI
IPC: C03B37/014
Filed: 1989-12-14
Abstract: PURPOSE:To minimize the contamination from a furnace core tube and to obtain the glass preform for optical fibers added uniformly with fluorine by heat treating an SiO2 glass particle body in specific two stages in a gaseous fluorine- contg. atmosphere, then vitrifying the body to transparent glass in an inert gaseous atmosphere. CONSTITUTION:The SiO2 glass particle body synthesized by a flame hydrolysis method is put into the furnace core tube and is dehydrated by a heating treatment in the gaseous chlorine system. The body is then subjected to the heating treatment in the atmosphere contg. the fluorine-based gas (e.g.; SiF4) to add fluorine to the SiO2 glass particle body. The furnace temp. is then set at the temp. from the same temp. as the fluorine addition temp. up to 1400 deg.C and the SiO2 glass particle body is subjected to the 2nd heating treatment in the fluorine-based gas-contg. atmosphere to shrink the SiO2 glass particle body to the extent of preventing the evaporation of fluorine in the outer peripheral part of the SiO2 glass particle body. The particle body is then vitrified to the transparent glass in the inert gaseous atmosphere, by which the glass preform for the optical fibers added with fluorine is obtd.

Title: Sliding member, supporting member, and combination of them with excellent fretting damage resistance
Inventor: HASHIZUME KATSUYUKI
IPC: F16C33/12
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To improve fretting damage resistance by providing a specific fine roughness to at least one on a back face of a back plate in a sliding member, which is assembled in a supporting member on the back face side, and on the front face of the supporting part. SOLUTION: In a sliding member,a sliding bearing alloy is stuck on the surface of a back plate, in which fine roughness of 4-15μmRz is provided on the back. If roughness of the back plate back face 20 exceeds 4μmRz , the tip of the back plate projection part 20a is crashed by plastic deformation in the part in which fastening stress is locally increased during assembly to a connecting rod 3, and the back plate and a connecting rod bore face 21 are brought into mutual contact uniformly with each other. Even if fretting is caused under a such condition in which a contact part is uniformly distributed and load distribution is unified, stress on the contact face is distributed between 20, 21 via a contact part 21a, so that damage is hardly caused. On the other hand, the roughness exceeds 15μmRz , noise is likely caused because of increase of a bearing clearance.

Title: Sensor device
Inventor: YAMAHIRA YUTAKA
IPC: H01L21/027
Filed: 1988-12-21
Abstract: PURPOSE:To decrease faults which are caused by an electrolyte by applying a voltage which is lower than an operating voltage to a light source or photoelectric converting element in the off period of a sensor and covering the surface of the sensor with a transparent coating material. CONSTITUTION:When a specific current flows from a power source 33, the LED 31 of the photosensor 21 illuminates. The collector of the phototransistor(PT) 32 of the sensor 21 is connected to the base of a transistor(TR) 35 and the emitters of the PT 32 and TR 35 are grounded to obtain an output corresponding to the quantity of photodetection at the collector of the PT 32 and the inverted output at the collector of the TR 35. Consequently, even when the PT 32 is off, the base-emitter voltage of the TR 35 is applied between the collector and emitter of the PT 32 and this voltage is lower than the operating voltage, so even if the electrolyte enters the gap between a mold part and the PT 32, its electrolytic reaction is not active; and the surface of the sensor 21 is covered with the transparent coating film to make the electrolyte hard to enter the sensor, thereby reducing trouble.

Title: Oscillation wave motor
Inventor: KITANI KOJI
IPC: H02N2/00
Filed: 1989-12-15
Abstract: PURPOSE:To enable linear driving of an object through a plane defined by opposite linear sections while producing unilateral force in the opposite linear sections by disposing a group of protrusions, having primary oscillation mode, on one linear section and disposing a group of protrusions, having secondary oscillation mode, on the other linear section. CONSTITUTION:Each protrusion in second group 1a2 is made thinner, in the circumferential direction, than each protrusion in first group 1a1. The second group 1a2 oscillates in secondary mode, and particles at the end thereof perform elliptical motion with approximately 180 deg. phase shift. Consequently, the particles perform motion in same direction at the highest point of the elliptical motion at the ends of both protrusion groups. Since the particles on the surfaces of first and second groups 1a1, 1a2 perform motion in same direction, frictional force between the first and second groups 1a1, 1a2 and a base 8 causes movement of an oscillator 1, along with a mounting table 4, in the vertical direction on the drawing. Since the driving force of both protrusion groups can be arranged unilaterally, shifted contact or irregular speed can be prevented as compared with a employing only one linear section.
