Title: Flow sensor and flowmeter
Inventor: MIYAZAKI YOSHIRO
IPC: G01F1/20
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To measure flow rate reliably while keeping high detection accuracy and low power consumption. SOLUTION: A heating means 5 is fed with power externally to heat a fluid flowing through a nozzle 3. The heated fluid is jetted through the jet nozzle and collides against a shaker 4 to alter the flow path and oscillates at least between two pyroelectric sensor groups SG1 , SG2 . Based on the output signals G1 , G2 from respective sensor groups SG1 , SG2 , a processing means 7 generates a flow rate signal SFL corresponding to the flow rate of fluid thus detecting the flow rate accurately while suppressing the effect of noise. Since a plurality of pyroelectric sensors are employed and the flow rate is detected thermally, high sensitivity is ensured. Furthermore, power consumption can be reduced substantially by providing a power generating means for supplying the heating means 5 with power while superposing on the external power supply.

Title: Discharge lamp lighting device
Inventor: HAMAMOTO KATSUNOBU
IPC: H02M7/48
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device preventing a discharge lamp from flickering or dying out by making it easy to secure a relatively high lamp voltage even in the event of deep dimmed lighting, and reduced in cost by simplifying its circuit configuration. SOLUTION: In this discharge lamp lighting device, the use of a switching element Q1 is partly shared by a chopper circuit 8 for reducing distortion of input current from an alternating-current power supply AC and by an inverter part 2 for high frequency generation, a direct-current voltage obtained at a smoothing circuit C4 by the function of the chopper circuit 8 is used as the power source of the inverter part 2, the oscillation output of the inverter part 2 is supplied to a discharge lamp via a resonance circuit 3, and the discharge lamp is dimmed by the change of a resonance voltage caused by varied frequency.  The on-duty of the switching element Q1 in the chopper circuit 8 is decreased as an operating frequency increases so that the output voltage of the smoothing circuit becomes high at the time of full lighting of the discharge lamp and becomes lower as the optical output of the discharge lamp decreases.

Title: Manufacture of interior elliptic tube
Inventor: OKUI TATSUYA
IPC: B21B17/14
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain the interior elliptic tube with complete roundness in outside diameter, having arbitrary ellipticity by shifting the caliber center positions of adjacent roll stands from a pass center in the roll gap extending direction of three roll gaps opposed to the groove bottom center of each caliber roll composing the caliber. SOLUTION: In a first stand and a third stand which exist before and behind, a flange part 2b with a small draft is positioned on the lower part of the stand, and a groove bottom part 2a with a large draft is positioned on upper part of the stand. Consequently, in the flange part 2b on the lower part of the stand, a wall-thickness increase is suppressed, and in the groove bottom part 2a on the upper part of the stand, a wall-thickness loss is accelerated. Therefore, the tube thicknesses of parts corresponding to up and down of the stand, are made thinner than other parts because thickness change movements in the second stand, and the first stand and the third stand existing before and behind of the second stand are overlapped. Consequently, the interior elliptic tube with complete roundness in outside diameter, having an elliptic inside surface whose major axis is in the vertical direction, is formed.

Patent JP-S6473301-A (JP)
Title: Single-mode star coupler
Inventor: TAKATO NORIO
IPC: G02B6/12
Filed: 1987-09-14
Abstract: PURPOSE:To narrow down the gap of an optical waveguide for connecting an input and an output optical fiber and to reduce its loss by structuring the optical waveguide for a directional coupler which is formed on a substrate and distributes light beams equally so that the optical waveguides crosses each other through the directional coupler which provides 100% coupling. CONSTITUTION:The directional coupler 20 which has an almost 100% coupling rate is formed at the position of a conventional optical waveguide instead of the optical waveguide. For example, one of optical signals distributed equally by, for example, a directional coupler 15 is incident on the directional coupler 16 and distributed equally. The other light signal is incident on the directional coupler 20, but the directional coupler 20 distributes almost 100% of the light power to another optical waveguide, so the other optical signal is guided to a directional coupler 16' and distributed equally. The optical signal which is incident from an optical fiber 17a for input is therefore guided out of respective optical fibers 18a-18d for output while almost equal to one another. Consequently, the gap of optical waveguides to be connected to the input and output optical fibers is narrowed down and the loss is reduced.

Title: Phase comparator
Inventor: AKASE YOJI
IPC: H04J3/06
Filed: 1988-09-14
Abstract: PURPOSE:To obtain a phase comparator not causing any data error even if timewise fluctuation or deviation of a pulse takes place by providing an optional area between an inhibit area and stable area caused on a time axis so as to apply phase comparison control. CONSTITUTION:The phase comparator is provided with a function giving a time width over a time of timewise fluctuation and deviation to an optional area 12 and holding the preceding state when the relation of frame phase is located in the optional area 12. For example, the inhibit area 12 is maintained in the mutual transfer from the inhibit area 10 to the optional area 12 and keeps stable state at the transfer from the stable area to the optional area 12 to inhibit the occurrence of a delay in the optional area 12. As a result, even if the relation of frame phase is located at each border, the delay in the time width over the pulse timewise fluctuation and deviation is not implemented and the preceding state is maintained, then the timewise fluctuation and deviation of a pulse is absorbed thereby preventing a data error.
