Title: Photoelectric device
Inventor: MOMOSE HARUHIKO
IPC: G02B7/32
Filed: 1984-03-05
Abstract: PURPOSE:To easily make a front surface flat so that light is prevented from straying and stains on the surface are cleaned up easily by coupling tips of light shield cylinder parts for projection and photodetection with the light shield member of a dust protective plate. CONSTITUTION:The dust protective plate 3 consists of an insert plate 31 made of a light-transmissive member and the light shield member 32 which is formed integrally with the insert plate 31 so that the front and rear surfaces of the insert plate are covered. The light shield member 32 is formed to surround window parts 31a-31c on the front surface of the insert plate 31 and also separate them optically from one another. Tips of a light shield cylinder part for projection which contains a projection part A and a light shield part for photodetection which contains photodetection parts B and B' are coupled with the light shield member 32 of said dust protective plate. Consequently, light is prevented from straying between the projection part and photodetection parts and its front surface is made flat easily to facilitate the cleaning of stains.

IPC: H01L29/732
Filed: 1987-02-24
Abstract: PURPOSE:To prevent the growth of granules from a polycrystalline silicon film region at the side wall surface of a groove, by using both selective epitaxial growing and non-selective epitaxial growing, performing sequential lamination, and obtaining an intended structure. CONSTITUTION:An insulating film 2 is formed on one main surface of a single- crystal semiconductor substrate 1. A specified groove 4 is formed in the insulating film 2. One main surface is exposed. A first single-crystal semiconductor layer 5 is formed in the groove by a selective epitaxial growing method. A second single-crystal semiconductor 13 is formed on the first single-crystal semiconductor layer 5 by an epitaxial growing method. A polycrystalline semiconductor layer 6 is formed on the insulating film 2. In this way, it is not necessary to perform the selective epitaxial growing under the state a polycrystalline silicon intermediate layer is present as in a conventional method. A problem of impairment of the quality of a single-crystal silicon region due to the growth of granules from the polycrystalline silicon can be solved.

Title: Electrophotographic printer
Inventor: MIYAZAWA YOSHINORI
IPC: B41J2/46
Filed: 1990-02-22
Abstract: PURPOSE:To enhance dot positional precision without adding an optical correction and further to print a wide recording sheet by controlling the light emission of the prescribed light emitting point of an exposing head at a prescribed position on a photosensitive body. CONSTITUTION:Curve-scanning is carried out along a guiding shaft 31 while a photosensitive drum 1 is rotated in the direction of an arrow 10. In other words, an exposing head 2 shown by a broken line shows a scanning starting position and an exposing head shown by a full line shows a scanning completion position. In the exposing head 2, 64 pieces of light emitting parts 36 are arranged on a straight line in a direction perpendicular to the shaft of the photosensitive drum 1 in the pitch of 1/300 inches, and an inverted image is formed on the photosensitive drum 1 by an image-forming lens 33. Since the photosensitive drum is moved by a distance coincident with the effective exposing time of the head when one scanning action is carried out, it can be continuously scanned with the next exposing head scanning action. Thus, the dot position precision is enhanced, and further, this electrophotographic printer which can print the wide recording sheet can be attained.

Title: Gas flow rate measuring apparatus
Inventor: IGARI TAKEO
IPC: G01F1/56
Filed: 1986-02-28
Abstract: PURPOSE:To measure even a small flow rate accurately while reducing troubles, by gauging the flow rate of a gas from changes in the resistance value between a pair of electrodes as caused when the gas to be measured passes between the pair of electrodes as bubbles in a conductive liquid. CONSTITUTION:Large bubbles 16 a of a gas 16 to be measured as formed when it is injected into a conductive liquid 14 are deformed into small bubbles 16b while the gas passes through a sponge-like electrode 18. As the gas 16 being measured passes in bubbles between the pair of electrodes in the conductive liquid 14, the resistance value between a pair of electrodes 18 and 18' changes and hence, the change in the resistance is detected with a measuring circuit 20 to measure the flow rate of the gas 16. So to speak, as the gas 16 passes between the pair of electrodes 18 and 18.., the resistance value increases between the electrodes 18 and 18'; the larger the flow rate of the gas, the higher the resistance value. Thus, the flow rate of the gas 16 can be measured by detecting changes in the resistance value with the measuring circuit 20.

IPC: G03B17/00
Filed: 1983-03-16
Abstract: PURPOSE:To brake a motor electrically only for a specific time by operating a pulse generating circuit almost simultaneously with the power-off operation of the motor, and sending an obtained pulse signal to the short circuit of the motor. CONSTITUTION:While the motor 18 is powered off, the output of an OR circuit 92 falls from H to L and a falling detecting circuit 93 generates a negative pulse signal with a 0.1sec pulse width. This negative pulse signal is inverted by an inverter 94 and supplied to an NAND circuit 95. The output of the NAND circuit 95 is held at L only for 0.1sec, so the short circuit of the motor 18 is formed to brake the motor 18 electrically. Further, the negative pulse signal outputted by the falling detecting circuit 93 is inputted to a strobe circuit 16 through an OR circuit 72, so a strobe is charged only for a specific time. Then, the short circuit is operated only for the specific time after the motor is powered down to brake the motor electrically, eliminating the unnecessary consumption of a battery.
