Title: Characteristic measuring apparatus for light-pickup actuator
Inventor: KENMOCHI SUSUMU
IPC: G01J1/00
Filed: 1990-05-25
Abstract: PURPOSE:To shorten measuring steps by measuring the power of the light beam from an actuator, and measuring the increase and decrease of the optical power which a are associated with the operation as the speed and the stroke of the actuator. CONSTITUTION:The actuator of material to be measured 5 is connected to an operation amplifier 3. Thus the actuator is driven. A light pickup is further connected to a light-output adjusting amplifier 4, and the light is emitted. The light beam is detected with a photodetector 1. Under this state, the optical power is increased and decreased with the movement of the actuator. Namely, when the light pickup approaches the photodetector 1, the amount of the light increases. When the light pickup goes away, the amount of the light is decreased. Therefore, the increasing and decreasing speeds of the light power are corrected with an analyzer, and the speed of the actuator is obtained. The absolute values of the increase and the decrease are corrected with the analyzer, and the values are made to be the strokes of the actuator. The output of the photodetector 1 at the maximum level is measured as the amount of the light power.

Title: Air-fuel ratio control method for internal combustion engine
Inventor: MOCHIZUKI KENJI
IPC: F02D45/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To reliably shift an air-fuel ratio by a desired amount irrespective of an engine operation state by changing a control constant after the output of an oxygen sensor crosses a slice level and a prescribed time elapses. SOLUTION: When a control constant for correcting a fuel injection time is increased or decreased in response to the change in output voltage of an oxygen sensor mounted in an exhaust system of an engine to control an air-fuel ratio and the output voltage crosses a slice level to a lean side (or a rich side), the control constant is increased (or decreased). Next, if the output voltage crosses the slice level again to a rich side before the first specified time lapses, the control constant is decreased. If the output voltage does not cross the slice level again to a rich side before the first specified time lapses, when the second specified time elapses, the control constant is decreased.

Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To efficiently perform solid-liquid separation of a coating material sludge by extending a formed member of a water tank bottom plate of a scroll chamber front part to form a scroll chamber and further extending it to the scroll chamber rear part to form a waste water gutter so that a coating material mist is collected by liquid films and liquid drops formed in the scroll chamber. SOLUTION: The coating material mist 4 is sent to a gas-liquid contact part 10 by the sucked air 2 sucked by an air discharge fan 1. In such a case, because a partition plate 8 for forming a sucking space 9 between the scroll chamber 7 and a liquid surface 6a is mounted on the liquid surface 6a of circulating water 6 in a water tank 5a, the circulating water 6 is formed into the liquid drops at the time of passing the sucked air 2a containing the coating material mist 4 at high speed, and the sucked air 2a containing the coating material mist 4 and the circulating water 6 are brought into gas-liquid contact with each other and simultaneously the collection by the centrifugal force is performed in the scroll chamber 7.  As a result, the coating material mist 4 incorporated in the circulating water 6 is separated from the sucked air 2b by eliminators 11a-11c to flow out to a water discharge gutter 13 as the circulating water 12 containing the coating material mist 4.

Filed: 1977-11-15
Abstract: PURPOSE:To change frequencies depending upon the amounts of a plurality of materials without changing frequency temperature characteristics by coating said materials in such places where no influences are given to coupling between longitudinal vibrations. CONSTITUTION:A piezoelectric vibrator 1 consists of a vibrating part 2, supporing part 3 and bridge part 4 and its electrode employs a full face electrode system. Broken lines 5, 6 respectively indicate the tangents which occur when the vibrating part 2 vibrates longitudinally in its short side direction. This vibrator 1 is mounted by bonding a supporing material to a supporting part 3. This vibrator 1 is mounted by bouding a supporting material to a supporting part 3. Materials 7 composed of a metal or insulator are coated at four corners of the vibrating parts 2. If these coatings at four points are of the similar thickness and size, the change in frequency owing to mass effect may be caused without accompanying any change in frequency temperature characteristics. In order to change the frequency, the frequency is lowered until the desired frequency is obtained by removing the weights and matching or the frequency is lowered by gradually increasing the thickness of the weights.

Filed: 1982-08-09
Abstract: PURPOSE:To simplify the closing operation of power source for a vehicluar radio by using a system in which the power source is closed in an interlocking manner with the operation of switches other than the power source switch. CONSTITUTION:The positive terminal of a battery 14 in closed state is usually connected with a power source interruption switch 15 becoming opened state by off-operation of a power source switch and also with a power source line in a radio circuit 8 through the relay contact 6a of a power source relay 6.

Title: Repeating amplifier
Inventor: HAMADA YASUSHI
IPC: H04N21/647
Filed: 1992-05-29
Abstract: PURPOSE:To prevent up transmission quality from being degraded by jump-in joint noise latent in air in an up transmission band frequency by performing up transmission between the distributing input/output terminal of the repeating amplifier and a subscriber terminal at a high frequency normally used for down transmission. CONSTITUTION:The down transmission uses a down transmission band at the high frequency of 70-45MHz, and the up transmission uses the up transmission band at the low frequency of 10-50MHz. At a directional coupler 15, an up transmission signal at the down transmission band frequency for return to be outputted to a branching path (p) is inputted to a gate switch 22. Then, only when the detecting signal of an access signal is outputted from an access signal detector 21, the up transmission signal is outputted from a gate switch 22 and inputted through an up distributing path (n) to a directional coupler 20. Namely, in the case of returning the up transmission signal at the down transmission band frequency from the terminal by the repeating amplifier, the access signal is sent from a CATV center to the repeating amplifier, the switch 22 is controlled, and the signal is returned to a down trunk line (d) by the directional coupler 20; As a result, the up quality can be prevented from being degraded by the joint noise.
