Title: Dust protective system for bicycle cable
Inventor: ODA HIROMI
IPC: B62L3/02
Filed: 1995-02-14
Abstract: PURPOSE: To prevent foreign matters from invading in a cable by arranging a nose cap which has an inner hole inserted the outer circumference of an outer easing end part and which is engaged with the car body of a bicycle, and a protecting pipe whose at least one end is connected to the nose cap. CONSTITUTION: A protecting pipe 20 is made of synthetic resin, rubber, a metal pipe, and the like. One end of the protecting pipe 20 is inserted in the small diameter part 14 of a nose cap 10. Since an inner cable 17 is covered with the protecting pipe 20, it is blocked that foreign matters such as sludge are invaded from a clearance (play) formed between the small diameter part 14 and the inner cable 17. The diameter of an inner hole 29 is formed smaller than the outer diameter of the inner cable 17, and a seal material 28 is made of soft materials such as rubber, and synthetic resin. Therefore, the inner cable 17 can be passed the inner hole 29. The inner cable 17 is slid on the outer end of the inner cable 17 and the inner hole 29 of the seal material 28 so as to eliminate the foreign matters. It is thus possible to prevent invasion of the foreign matters.

Title: Ultrasonic motor
Inventor: ITOU MOTOAKI
IPC: H02N2/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To properly control the rotation of a rotor without fail when both a stator and the rotor are provided with a piezoelectric vibrator. SOLUTION: Piezoelectric vibrators 5v, 6v are made of one and the same material and formed into one and the same shape, and at least the vibrating portions of elastic bodies 5e, 6e used for driving are made of one and the same material and formed into one and the same shape. The numbers of natural oscillations of oscillating bodies 5g, 6g comprising the piezoelectric vibrators 5v, 6v and at least the vibrating portions of the elastic bodies 5e, 6e used for driving are match with each other. When the piezoelectric vibrators 5v, 6v are supplied with a signal of the resonance frequency of the oscillating bodies 5g, 6g or a frequency close to the resonance frequency in this state, traveling waves produced at the pressure-welded faces can be method with each other.  As a result, the rotation of the rotor 6 can be properly controlled properly by continuously shifting the engaging lock position of the traveling waves. In addition, since both the numbers of natural oscillations are shifted in the same direction by the same amount, the engaging lock of the traveling wave will not release and the rotation of the rotor 6 can be controlled properly without fail, even of the numbers of natural oscillations of the oscillating bodies 5g, 6g are shifted due to effects of temperature, humidity, load or the like.

Title: Electrolyte impregnating method of fuel cell
Inventor: MIYOSHI NOBUO
IPC: H01M8/04
Filed: 1982-03-25
Abstract: PURPOSE:To familiarize the electrolyte with an electrode reaction layer by performing a preliminary discharge at a low load after impregnating the electrolyte so as to transfer the electrolyte from a matrix layer to the electrode reaction layer in a matrix type fuel cell. CONSTITUTION:After a block cell is heated, a preliminary discharge is performed at a low load, thus the electrolyte being held in a matrix is expanded by heat and transferred to an electrode reaction layer, in addition, water is generated in fine holes of the electrode reaction layer due to the electrochemical reaction in the cell, creating a condition that the electrolyte is apt to move to part of the electrode reaction layer, thereby part of the electrolyte is transferred to the electrode reaction layer so that the electrode reaction layer is familiarized with the electrolyte. By starting a regular operation after feeding the electrolyte which is lacking in the matrix, stable electrical characteristics can be maintained for a long time with the electrolyte not being transferred to the electrode reaction layer.

Title: Device for optical analog signal transmission
Inventor: KANEKO SHINICHI
IPC: H04B10/2537
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent C/N deterioration through the use of an inexpensive semiconductor laser with a wide spectral line width by modulating the oscillation wavelength of laser light by which a semiconductor laser device oscillates a modulation wave source at a frequency lower than the signal band of an optical analog signal. SOLUTION: A low-frequency source 31 for modulating laser light into the low frequency is connected to a semiconductor laser 30 as a modulation wave source. The semiconductor laser 30 becomes equivalent to a light source whose spectral line width becomes considerably large (phase noise is large), since the low-frequency source 31 modulates the oscillation wavelength with the low frequency. Noise by relay diffusion is scattered to the wide band, and noise power entering the signal band can be reduced. Thus, C/N deterioration after optical fiber transmission can be reduced by modulating the oscillation wavelength of the semiconductor laser 30 with the low frequency. Thus, the inexpensive semiconductor laser 30 with large spectral line width can be used as a light source.

Abstract: PROBLEM TO BE SOLVED: To reduce a deterioration in an image even at a slow shutter speed at which the influence of a big shake greatly appears by providing a release time lag changing means for varying a release time lag, in accordance with a shutter speed as the time of executing photographing. SOLUTION: When the fact that the operation of half-depressing a release button 13 is executed to generate an SW1 signal is detected, photometric information is inputted from a photometry circuit 4 and the shutter speed (ts) is obtained on the basis of this photometric information. Then, focal distance information (fz) is inputted from a zooming position detecting circuit 15. Continuously, an allowable shake quantity is obtained from the shutter speed (ts) and the focal distance (fz). For instance, 'fz×ts' is calculated and the release time lag (tr) is obtained from this calculated value. Standing by is executed until a time (t) of the obtained release time lag (tr) lapses from the generation of an SW2 signal as an exposure starting signal. A shutter is opened/closed with a shutter opening/closing circuit 16 by the lapse of this time.

Title: Outdoor equipment for air conditioner
Inventor: KINOSHITA KANJIRO
IPC: F24F5/00
Filed: 1995-03-08
Abstract: PURPOSE: To improve a passing air velocity distribution of an air blow-off grille and reduce an operation noise of outdoor equipment by dividing a blow-off air flow produced by an axial fan into two in the radius direction. CONSTITUTION: When an axial fan 1 is driven, an air flow W blown off from the axial fan 1 is adapted to flow especially smoothly through an air blow off enlarged space S of two layers divided into two directed at an air blow-off grille 3 by a horn-shaped flow control material 14 which turns together with an impeller 6 of the axial fan 1. It is, therefore, possible to produce no diverting flow portion in the passing air velocity distribution of the blow-off air flow W passing through the blow-off grille 3 and prevent a reduction in the passing air capacity without degrading the blow-off air capacity on the whole. This construction makes it possible to reduce a noise produced when the air is passing through the blow-off air grille 3. Therefore, the operation noise of outdoor equipment can be reduced.
