Filed: 1991-02-28
Abstract: PURPOSE:To eliminate variation in measuring a distance to a screen caused by the flickering of a fluorescent lamp in the case of automatically performing focusing in a projecting device such as an overhead projector, etc. CONSTITUTION:When a switch SW1 for focusing is depressed, the point of time when the phase of commercial AC becomes zero next is detected by a zero cross detection circuit 63, and a trigger signal is outputted to an action timing instruction circuit 70 from a 1st monostable multivibrator 65 in this phase. After the lapse of a specified time after the trigger signal is outputted, a rangefinding arithmetic circuit 50 fetches the intensity of external light, and removes it to measure the distance. In accordance with the measured distance, a stepping motor 37 is rotated to move a projection lens up and down, so that the focusing is performed. Therefore, the effect of intensity change in synchronism with the commercial AC, such as the flickering of the fluorescent lamp, is removed and the distance is accurately measured.

Title: Liquid drop jet device by use of rayleigh mode surface acoustic wave
Inventor: SHIOKAWA SACHIKO
IPC: B41J2/065
Filed: 1989-03-14
Abstract: PURPOSE:To miniaturize a device and to simplify a structure by providing an input electrode pair applying an AC voltage on the surface of a piezoelectric substrate and putting liquid splashed to a propagation path for a Rayleigh mode surface acoustic wave on the surface of the piezoelectric substrate. CONSTITUTION:An input electrode pair 2 exciting a Rayleigh mode surface acoustic wave with the aid of an AC electric signal provided on the surface of the substrate 2 with cut faces, which is composed of piezoelectric material generating the Rayleigh mode acoustic surface wave, and a liquid 3 to be splashed is put on a propagation path for the Rayleigh mode surface acoustic wave on the substrate 1. When AC electric signals obtained from an AC electric signal generator 4 and a pulse signal generator 5 intermitting AC electric signals are applied to the substrate 1 from the input electrode pair 2, the substrate 1 excites surface acoustic waves, which propagate along the surface of the substrate 1. When liquid is added to a Rayleigh wave possessing progressive wave characteristics out of the surface acoustic waves, it emits a longitudinal wave to the liquid while propagating along the interface between the substrate 1 and the liquid 3. Consequently, a part of the liquid 3 on the propagation surface turns into a liquid drop to splash out. Thus, the structure is simplified and the device is miniaturized.
