Inventor: EDA MASATOSHI
IPC: F16C33/10
Filed: 1986-04-17
Abstract: PURPOSE:To enable oil to be supplied to a supply oil port in a rotary shaft, by providing two floating seal rings, which are peripherally provided on the rotary shaft having a bearing metal in the internal peripheral surface, before and after the axial direction of a supply oil hole and a housing, which contains these rings, while leak oil collecting seal devices in both end parts in the axial direction of said housing. CONSTITUTION:Lubricating oil, supplied from a lubricating oil pump, is allowed to flow into a peripheral surface-type oil supplier from a supply oil port 17, provided in a housing 5, and most of the oil, which passes through a supply oil hole 19 provided to be drilled in a rotating solid shaft 25a, is introduced to a concentric hole 20. The lubricating oil leaks by its pressure difference from a clearance between a bearing metal 2 in the internal peripheral surface of a floating seal ring 1 and the solid shaft 25a, but this leaking oil, which is accumulated leak oil collecting seal devices 11 set to both ends of housings 5, 6 and collected from a discharge oil hole 18 provided in the seal ring, is collected to a lubricating oil tank. In this way, the lubricating oil can be supplied to the rotary shaft in the inside of a double contrarotating propeller device.

Title: Photosensitive heat-sensitive composition
Inventor: YASUMORI AKIYOSHI
IPC: G03C1/735
Filed: 1979-07-13

Title: Resin lens
Inventor: IIZUKA TAKAYUKI
IPC: G02B3/00
Filed: 1994-04-04
Abstract: PURPOSE:To prevent power variation caused by a change in the refractive index distribution by moisture absorption by forming a cross-sectional shape on a surface vertical to the first direction in a shape whose optical axis directional length becomes smaller than a length in the second direction perpendicular to both the first direction and the optical axis. CONSTITUTION:A lens has the optical axis O in the Z axis direction, and is formed in a long and narrow shape extending in the Y axis direction. An X-Z cross section of the lens is formed in an almost rectangle. Since an X axis directional length Lx of this X-Z cross section is longer than a Z axis directional length Lz, the refractive index distribution is mainly formed along the X axis. In other words, in lines (n1 to nk) connecting points where refractive indexes are equal to each other, a length of a part extending in parallel to the Z axis becomes smaller than a length of a part orthogonal to the Z axis. Since light advances in the Z axis direction, the light passing through the lens is emitted from a refractive surface without being practically influenced by the refractive index distribution. Thereby, lens power is stable in spite of variation in the refractive index distribution.

Title: Photo-cvd apparatus
Inventor: HASHIZUME YASUYUKI
IPC: H01L21/263
Filed: 1987-04-09
Abstract: PURPOSE:To prevent a material from being deposited on the rear face of a light transmission window while enabling it to be deposited on a substrate more rapidly, by once optically enlarging a diameter of a laser beam and then focusing it onto the substrate. CONSTITUTION:A laser beam 2 is once enlarged by a concave lens 5 and directed to a point 20 on a substrate 8 by a convex lens b. A chamber 10 is filled with raw gas, which is excited and decomposed by the laser beam 2 between the rear face of a light transmission window 21 and the substrate surface 20. Since the raw gas is excited by absorbing photons, probabilities of the raw gas being excited are proportional to densities of photons passing therethrough. That is, if the intensity of laser beam is constant, areas of the laser beam transmitted by the light transmission window 7 are inversely proportional to probabilities of the raw gas being excited near the window 7. For that reason, the area of the laser beam 2 to be transmitted by the window 7 is enlarged by means of the convex lens 5. Accordingly, concentration of the raw gas excited and decomposed near the window is low.

Title: Optical thickness measuring method of plate-shaped transparent body having ruggedness
Inventor: YAMAUCHI HIDEO
IPC: G01B11/06
Filed: 1993-03-24
Abstract: PURPOSE:To execute the thickness measurement even in the presence of the ruggedness by measuring the angle of incidence by the position of the reflected light from the surface of the object to be measured, and calculating the thickness from the distances of the reflected light on each side in the simultaneous measurement. CONSTITUTION:A plate G to be measured is irradiated with a laser beam of a laser beam source LS through a converging lens L1, and the reflected lights from the front and rear surfaces reach linear image sensors S1, S2 through a light receiving lens L2 and a beam splitter BS. The direction of the reflected light due to the ruggedness of the body to be measured is obtained as the position of the light-receiving spot on the sensor S1 by placing the sensor S1 at the rear focal point of the lens L2, and placing the sensor S2 at the conjugate point (focal point) of the irradiation point on the plate G, and the distance of the reflected light on each surface in the direction orthogonal to the optical axis of the reflected light is obtained as the clearance between two light spots. The thickness of the plate G is easily computed by a microcomputer by making the values of the sensors S1, S2 as the input values.

Filed: 1987-04-11
Abstract: PURPOSE:To set an incoming tone in response to the surrounding environment by using a common circuit to sound volume adjustment for other signal tone so as to apply sound volume adjustment of the incoming tone. CONSTITUTION:A user sets an optional incoming sound volume, then the incoming tone starts ringing at the set sound volume, and the incoming signal is counted by a control section 16 to measure and output the elapsed time from the start of incoming call. The output controls the incoming sound volume. Moreover, the output of an electronic volume section 14 is fed back to the control section 16 to change up to the maximum incoming sound volume even with any initial setting value. Thus, the user can set the incoming sound volume depending on the surrounding state, and the control section 16 distinguishes the incoming signal from the signal line signal to set the sound other than the incoming signal optionally without changing the setting of other sound quality at all times.

Title: Vertical deflector of video display
Inventor: JIEEMUZU ARUBAATO UIRUBAA
IPC: H03K4/69
Filed: 1989-04-07
Abstract: PURPOSE: To stabilize an image by providing a service mode circuit, operating to maintain a DC-preventing capacitor to be in a charging state in the period of operating in a service mode, so as to prevent the unnecessary oscillation of a power source. CONSTITUTION: In order to make a television receiver operate in the service mode, a mode-switching signal is switched to a low state to disconnect the conductivity of a transistor Q9 . When the transistor Q9 is disconnected, a current path for charging a capacitor C1 through a resistor R11 is opened. Then, the capacitor C1 is no longer charged, and the voltage of the plate of a capacitor C2 combined with this capacitor C1 becomes VD. As a result, the generation of a lamp voltage 27 is stopped. A resistor R10 prevents leak current from charging the capacitor C1. Consequently, a capacitor Cv is maintained in the state of being charged at nearly +12.5 volt by the operation of the transistor Q9 in the operation period of the service mode.

Abstract: PURPOSE:To demodulate effectively a data even if some bit errors take place in case of presence of many error rates as the case of an optical disk by calculating a humming distance with an expected value and selecting out a minimum distance. CONSTITUTION:As soon as an input signal 8 read from, e.g., a magnetic disk is inputted to a shift register 1, a counter 2 uses a clock 11 to count a bit number of the signal 8 inputted.
