Title: Optical recording method
Inventor: YOSHIIKE NOBUYUKI
IPC: G11B7/243
Filed: 1985-03-15
Abstract: PURPOSE:To improve the storage density of information by changing the light intensity or the light irradiation time in the stage of irradiating the light thereby controlling the change quantity of the light absorption band to several stages in the stage of using a material the light absorption band of which changes when irradiated with the light as a recording material and subjecting the material to optical recording. CONSTITUTION:A tungsten oxide layer 2 as the recording material is deposited by a vapor deposition method to 6000 Angstrom  on, for example, a glass substrate 1 (may be plastic, metal or ceramics) and further an SiOx film 3 is laminated as a protective film to 3000 Angstrom  thereon by which the recording material is formed. The color change density of the recording material can be stepwise controlled according to the stepwise irradiation when the irradiation light energy is stepwise irradiated to such recording material. The light irradiation energy is proportional to the intensity and time of the irradiation light and therefore the control of the irradiation energy is made possible by changing the intensity of the irradiation light or the irradiation time.

Abstract: PROBLEM TO BE SOLVED: To surely wash and remove the stuck material on the surface of a metallic strip by spouting washing water onto the surface of the metallic strip to become not more than the saturated vapor pressure to obtain the washing water containing the vapor bubbles, destroying the vapor bubble on the surface of the metallic strip to generate the shock wave and washing the surface thereof. SOLUTION: The washing water is spouted to a gap 4 between washing water spouting nozzles 2, 2a arranged at the front and the back surfaces of the metallic strip 1 and the metallic strip 1. The washing water is passed through a narrow gap (b) from a first wide gap (a) and shifted to a second wide gap (c) and drained. Dynamic pressure of the washing water is raised and the static pressure thereof is lowered on the way of shifting from the first wide gap (a) to the narrow gap (b) of the washing water with the Bernoulli's theorem. The static pressure is changed to not more than the saturated vapor pressure to generate the vapor bubble. When the washing water is shifted to the second wide gap (c), the static pressure is raised and the vapor bubble is broken and made to the shock wave. The narrow gap (b) is 10-10<3> μm and formed as a gentle convex curve.  The supplying pressure of the washing water is regulated to 1-10<2> MPa and the supplying quantity thereof is regulated to 10<2> -10<4> l/min.

Title: Thermal air amount measuring apparatus for internal combustion engine
Inventor: TANIMOTO KOJI
IPC: G01F15/12
Filed: 1987-03-09
Abstract: PURPOSE:To reduce the change of a thermal flowmeter with the elapse of time by reducing the amount of the dust particle adhered to a heat-sensitive resistor, by providing a conductive air pervious body to the air passage part on the upstream side of the heat-sensitive resistor in a thermal air amount measuring apparatus in an earthed state. CONSTITUTION:The dust particle introduced into an air cleaner passes through an air cleaner element 10 to be charged by the friction with the element 10 but the charge of the charged dust particle is neutralized by the ion formed by the discharge of a conductive fiber 11. Since the dust particle having residual charge not neutralized is collided with and adhered to a metallic distributing element 12 as an earthed conductive air pervious body and the residual charge is leaked, the charge of the dust particle reaching the detection element of a heat generating resistor 6 is reduced to a large extent. As a result, the electrostatic force acting on the dust particle becomes a negligible level and the adhesion amount of the dust particle to the surface of the detection element of the heat generating resistor 6 is reduced and the change of a thermal flowmeter with the elapse of time can be reduced.

Title: Discharging circuit of word line
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/415
Filed: 1983-03-31
Abstract: PURPOSE:To prevent the resise of the potential of a word line and the double selection by controlling to attenuate with a prescribed time constant the discharge characteristics of the discharge current of the word line which is to be extracted out of the word line when a selection mode is switched to a non- selection mode. CONSTITUTION:The discharge current IDIS is gradually attenuated with the prescribed discharge characteristics since the sudden turn-off of the current IDIS will cause the rerise Q of potential. A word line discharging circuit WDC consists of a dummy cell DC and a transistor TD for the control of a word line discharge current. The base potential V'B of a transistor TME rises up when the rerise Q of potential starts within a memory cell MC which is changed to an NS mode from an S mode. Then a transistor TD is biased deep and continues the extraction f the word line discharge current in response to the potential V'B. In such a way, a practical discharging circuit for the word line is produced with the extraction of the discharge current I''DIS corresponding to the change of V'B.
