Title: Vortex flowmeter
Inventor: WADA MASAMI
IPC: G01F1/32
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To make the burst wave number extraordinarily small and reduce the noises of a conduit and the power consumption by sample-holding wave detection signals in a predetermined time interval at a transient state before transmitted ultrasonic waves reach a stationary state. SOLUTION: In response to a reference signal VS1 , a driving circuit 29 impresses to a wave transmitter 22 a driving signal VD wherein a group of bust waves of an extraordinarily small burst wave number intermittently repeats in a cycle faster than a frequency of a vortex with a constant pause. The wave transmitter 22 transmits to a wave receiver 23 ultrasonic burst waves via Karman's vortex street 34 which have an envelope of a mountain-like waveform finishing in a transient state before an amplitude reaches a stationary state. Burst waves VR received 23 are turned to pulses by a waveform-shapind circuit 26 and a phase of the waves is detected 27.  A sample hold circuit 31 sample- holds a phase detecting signal VD in a fixed time interval a predetermined time later from a fixed position of the received wave VR in accordance with a gate signal VG output synchronously with a reference signal VS2 . An operational device 32 operates a flow rate with the use of the signal VD.

Title: Laser scanning optical system
Inventor: FUJINAWA MASAAKI
IPC: G02B26/10
Filed: 1982-03-12
Abstract: PURPOSE:To compensate the shift of position of the laser scanning with a simple constitution and without requiring super-precise processing of a rotary polyhedral mirror, by detecting the scanning position of the laser light, and controlling the light emitting position of a laser light source in response to the detected scanning position. CONSTITUTION:A laser light source 1 has three light emitting parts A, B and C. A rotary polyhedral mirror 2 leads the laser light given from the light source 1 to a prescribed direction. An image forming lens 3 forms the laser light reflected by the mirror 2 into an image on a photosensitive drum 5 for laser printer. The image-formed laser light scans on a laser scanning position detector 4 and the drum 5 with revolutions of the mirror 2. The scanning position of the laser light radiated from the part B varies like a', b' and c' owing to the face falling of the mirror 2. In order to avoid this effect, the light emitting position of the light source 1 is controlled by detecting the scanning position of the laser light due to the face falling of the mirror 2.
