Title: Optical information reader
Inventor: GOTOU AKIYA
IPC: G11B7/08
Filed: 1977-11-15
Abstract: PURPOSE: To achieve the miniaturization of pickup head part and simplification of focusing means by using optical fibers for transmission and reception of signal light and integrally providing focusing optical fibers.  
     CONSTITUTION: A read light source, a beam splitter and photo detector are disposed in the position away from a disc 1. A signal light transmitting-receiving optical fiber 6 1  as a pickup head part is disposed between these and the disc 1. In adjacent to this, forcusing optical fibers 6 4 , 6 5  whose end parts are so tilted as to view the focusing point of the read light beam are disposed. The disc 1 side thereof is held by holders 10 1 , 10 2  to be made elevatable. This causes the reflected light beam having been modulated with the read light beam and disc 1 to be transmitted through the optical fibre 6 1 . In addition, the output light detected in the optical 6 1  and the output light detected in the optical fiber 6 1  and the output light detected in the optical fibers 6 4 , 6 5  are compared and the holders 10 1 , 10 2  are so vertically moved as to balance both, whereby focusing controlling is accomplished.

Inventor: ASARI SHIGEATSU
IPC: H03J7/28
Filed: 1978-11-06
Abstract: PURPOSE: To ensure an accurate setting for the sweep frequency to the lower or upper limit as well as to increase the sweel speed by setting the pulse duration of the preset pulse larger than the reset time constant of the voltage control oscillator.  
     CONSTITUTION: Monostable multivobrator 23 is connected to the output end of preset pulse PP generator 22 to make the duration of PP larger than the reset time constant of voltage control oscillator VCO5. And no countings is given to clock pulse CP19 for the period when the output pulse of vibrator 23 is applied to counter 20, and the counting is started again at the time point when PP disappears after the oscillation frequency of VCO5 is reset to the lower limit. As a result, the reception unable range never exists, and the sweep is always carried out from the frequency of the lower limit. Furthermore, the sweel speed can be increased since the extension of the duration of CP is not necessary unlike and conventional case.

Title: 2-phase stepping motor
Inventor: SUZUKI YASUO
IPC: H02K37/12
Filed: 1985-06-24
Abstract: PURPOSE:To reduce the thickness and the manufacturing cost of a stator pole of a 2-phase stepping motor by opposing N- and S-poles to a radially magnetized rotor disk to concentrically dispose two doughnut plate-like stator poles of different radii. CONSTITUTION:A plurality of N- and S-poles are alternately magnetized radially to form a rotor disk 7. Two poles 4a, 4b arranged alternately in a zigzag manner on the inner and outer peripheral surfaces of a pair of annular yokes with pole teeth of the same number as the rotors are disposed at 90 deg. of electric angle displaced concentrically to form a stator pole plate 4. The poles 4a, 4b are magnetized by two annular coils 2, 3 disposed concentrically to rotatably drive the disk 7. Thus, since two sets of stator poles are disposed in the same plane, the flatness is enhanced. The poles plates 4 can be also manufactured by one punching work.

Abstract: PURPOSE: To provide an internal combustion engine of the type in which two suction valves are disposed side by side on the upper surface of combustion chamber for supplying mixture having different air-fuel ratio, wherein velocity of flow of these two mixtures and weight of air contained therein are controlled appropriately to produce a stable laminar flow of these two different mixtures.  
     CONSTITUTION: Mixture supply sources 10, 13 for supplying a relatively rich mixture and a relatively lean mixture are connected respectively to a first and a second suction ports 3, 5 which are disposed symmetrically in the upper surface of combustion chamber 1. Here, through control of a first and a second throttle valves 8, 11 disposed in respective mixture supplying sources 10, 13, amount of suction air at least in low-load operational range of engine is determined as follows. That is, providing that weight of air introduced from suction ports 3, 5 is G 1 , G 2 , respectively, G 2  is made greater than G 1 . Further, velocity of rich mixture supplied from suction port 3 is made relatively low whereas that of lean mixture supplied from suction port 5 is made relatively high. With such an arrangement, it is enabled to produce a stable laminar flow of two different mixtures and thus to purify exhaust gas effectively.

Title: Manufacture of electron tube and electron tube
Inventor: MIFUNE TATSUO
IPC: H01J29/07
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To resolve deterioration of an image quality by forming an electron reflection membrane formation amount below a specific amount, and inhibiting doming, by applying a coating compound which mainly contains sol-state oxide or alkoxide of metal having an atomic number of 40 and above, to the electron gun side of a shadow mask. SOLUTION: An electron tube which forms an electron reflection membrane formation amount of which is below 2 mg on the surface of an electron gun side of a shadow mask is obtained. At least one among sodium silicate, potassium silicate and lithium silicate are preferably used as a binder of the coating compound, and water is preferably used as a solvent. The shadow mask 1 is set in the physical relationship that a plane 1a opposes to a sputter target 7, because the membrane is formed on the surface 1a of the electron gun side of the shadow mask 1 by a sputtering device. For example, bismuth oxide is used as the target 7 and impressed with voltage by a high-frequency power supply 8.  The size of the target 7 is approximately twice as much surface area as one side of the shadow mask 1 in order to lower an effect caused by a distribution of membrane thickness at the time of the membrane formation.

Filed: 1988-06-03
Abstract: PURPOSE:To prevent abrupt starting as well as to make it simple to keep a running pedal fixed by allowing the footing of a brake pedal to disable automatically the footing of the running pedal. CONSTITUTION:When a running pedal is depressed, a continuously variable transmission is shifted in increment from its neutral position so as to be shifted to high speed running in order depending on the footing angle of the running pedal 2. When the running pedal 2 is returned back with the footing slackened, the transmission is returned back to the neutral position so that running is suspended. When a brake pedal is depressed, a running device is controlled. In this case, when the brake pedal 1 is depressed sufficiently enough, a running lock device is actuated while being interlocked with the action of the brake pedal, which situation disables the running pedal 2 from being depressed so as to be fixed so that the pedal is in a parking brake position.
