Title: Full type ball bearing device
Inventor: HAYASHIDA KAZUNORI
IPC: F16C19/56
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a full type ball bearing device which can reduce a rotary torque as a whole and extend its life. SOLUTION: A rotary shaft 5 is supported rotatably to a housing 3 by first/ second full type ball bearings 401, 402 separating to the axial direction of the sideways rotary shaft 5. The first a full type ball bearing 401 is near the load relatively. The load capacity of the first a full type ball bearing 401 is made bigger than that of the second a full type ball bearing 402. Therefore, for example, the number of ball of the second a full type ball bearing 402 is less than that of the first a full type ball bearing 401. As a preloadby a cantilever support is applied to the first a full type ball bearing 401, it is no problem even if the load capacity is lowered.

Title: Conveying method in press line
Inventor: SHOJI MASAYOSHI
IPC: B65G25/04
Filed: 1984-12-26
Abstract: PURPOSE:To shorten the length of a press line as well as to make its structure so simple enough, by constituting this press line so as to carry in or out a work to or from plural presses disposed in series without spacing, in a way of driving a set of shuttle conveyors in cooperation with a lifter of a press machine. CONSTITUTION:A shuttle bar 51 goes forward so as to pierce through each of presses 38-40 in a state that processed works W1 and W2 in each of presses 39 and 40 are uplifted with a lifter 45. Next, the lifter goes down, and these works W1 and W2 are mounted on a finger 51a of the shuttle bar. Simultaneously, a work W3 is transferred onto the finger 51a on a press 38 from a marriage stage 36. The shuttle bar 51 is retracted in a direction toward one process portion (c), making the lifter 45 go up, and the shuttle bar 51 is brought back to a stand-by position and pressed. Accordingly, the work W1 is carried out. With this constitution, the length of a press line is shortened whereby an idle lifter becomes useless.

Title: Duplication-proof hologram
Inventor: NISHIKAWA SHINGO
IPC: G03H1/18
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a hologram impossible to be duplicated. SOLUTION: In this hologram, patterns are expressed by the contours of a recording region 7 of a volume phase type hologram formed by the interference of two wavefronts 2, 3 randomly subjected to phase modulation according to positions by random phase plates 4, 5. Even if another recording material is superposed on the hologram and coherent light for duplication is made incident from the recording material side, the light transmitted through the photosensitive material does not generate diffracted light from a recording region 7 recorded with interference fringes and, therefore, the duplication of the hologram recorded with the patterns expressed by these contours is not possible. Then, the duplication-proof hologram is suitable for the hologram for preventing forgery of identification cards, etc.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: NAKANO KAZUO
IPC: F02D41/00
Filed: 1986-11-19
Abstract: PURPOSE:To permit a good feeling of acceleration to be obtained even when an engine is in moderate acceleration, by providing a load parameter detecting means while discriminating an increase direction of the detected engine load in no relation to the rate of its change and inhibiting a lean control in the load increasing direction. CONSTITUTION:While an engine is in operation, in a control circuit 20 having a load increase direction discriminating means 11 and a lean control inhibiting means 12, a detected value by a throttle sensor 10 is converted into a value TA by A/D conversion, and this value TA is discriminated for whether or not it increases from the preceding time value TA. When the discrimination is YES, next the increment of a counter, measuring a number of times of continuing an acceleration condition, is executed, and a degree of the counted value C is compared with a predetermined value (x). And in the time of a relation where C>x, a lean control of air-fuel ratio is inhibited by deciding the engine to be placed in an acceleration condition. In this way, the engine, increasing its fuel injection quantity from an arithmetic value for obtaining the preset air-fuel ratio in accordance with an operative condition of load or the like, controls air-fuel ratio to a rich state.

Title: Light amplifier and device for monitoring optical transmitting line
Inventor: KAMIMURA ARITOMO
IPC: H04B10/293
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To minimize loss of signal light, before the signal light is made incident on a rare earth-doped fiber as an amplifying medium since its increase portion is directly reflected in the noise characteristic (noise figure) deterioration of a light amplifier, because the conventional light amplifying method makes the signal light to be amplified pass through a wavelength-dependent optical coupler, whose loss is relatively large until the signal light reaches the rare earth doped fiber. SOLUTION: Exciting light outputted from an LD for excitation is made incident from the back of a 1st rare earth doped fiber 3 via an optical circulator 1 to reach an optical filter 4 for excitation light reflection. The major part of the excitation light is reflected from the filter 4 to be made incident on the fiber 3 again from the front. Light amplification of low noise can be realized, because the excitation light is made to flow in both directions to increase optical electric field strength in the incident part of the fiber 3, so that a population inversion state can be formed efficiently.

Title: Phase comparator
Inventor: KEGASA MITSUYOSHI
IPC: H03L7/085
Filed: 1989-10-24
Abstract: PURPOSE:To obtain a phase comparator with low noise by connecting inputs of plural phase comparators in parallel, adding phase outputs at each output, and extracting a difference output so as to improve the S/N. CONSTITUTION:Since phase detection output components among output signals of EOR gates 31-34 are in-phase, currents of four outputs are added after passing through resistors 41-44 to be 4-times phase detection output. However, the noise component in output signals of gates 31-34 is an independent signal, when the 4 independent noise components are in-phase, they are added after passing through the resistors 41-44 and when they are opposite in phase, they are cancelled after through the resistors 41-44. That is, when N sets of noise components are added, the total noise component is in general the total sum of each of noise power and when the noise power of each is equal to each other, the noise power is a multiple of N and the noise current is a multiple of N<1/2>. Thus, in the case of N=4, the noise goes to 41/2=2 and the S/N is improved double.
