Title: Method and device for recording and reproducing information, and information recording medium
Inventor: OKABE MASAHITO
IPC: G11B11/105
Filed: 1994-06-24
Abstract: PURPOSE:To perform accurate and speedy composition by recording information for positioning at a non-image formation part on a liquid crystal recording medium and composing a color image on the basis of the information. CONSTITUTION:A prism 80 and a pattern electrode 70 for recording the position information are installed in the information recording device, and respective images of R, G, and B separated by the prism 80 are imaged on an optical sensor 10. The pattern electrode 70 and liquid crystal recording medium 20 are put opposite each other and a voltage is applied between both electrodes; when a read is made by an image reader, the electrode pattern can be recognized. Namely, the pattern electrode 70 and prism 80 are fixed to the information recording device, so crosses recorded by the pattern electrode 70 never changes in position relation at all times. Therefore, when image information is recorded and the images of R, G, and B are put together, the images of the three colors can accurately be put together by recording relative positions of the crosses recorded by the use of the pattern electrode 70.

Filed: 1992-05-11
Abstract: PURPOSE:To allow an object transmitter-receiver to surely receive a signal by allowing the transmitter-receiver to disconnect the connection between itself and a transmission line and to connect them again after lapse of a prescribed time. CONSTITUTION:When a transmitter-receiver 11 calls a transmitter-receiver 12 and the transmitter-receiver 12 cannot demodulate the signal because its reception level is small, the transmitter-receiver 11 sends a control signal C13 by a command of an external processing unit 8 connecting to the transmitter- receiver 11. The control signal C13 enters the transmitter-receiver 13, a logic circuit 5 discriminates the content of the signal to open a switch 2 and sends a count start signal S1 to a timer 6. With the switch 2 opened, the transmitter- receiver 13 is disconnected from a transmission line 9 and the reception level of the signal sent by the transmitter-receiver 12 is increased in the transmitter- receiver 11 in this state and the level of the signal sent by the transmitter- receiver 11 is increased in the transmitter-receiver 12, and then the transmission reception between the transmitters-receivers 11, 12 are attained. Furthermore, the timer 6 counts a prescribed time and the logic circuit 5 sends a command to close the switch 2 based on the time.

Abstract: PROBLEM TO BE SOLVED: To improve fuel corrosion resistance after working by forming cracks of specific density in a Zn alloy film of a surface treated steel sheet where a chromate film is formed on the Zn alloy plating film of specific composition. SOLUTION: A Zn-X alloy electroplating film, containing at least one kind selected from 3-18%, by weight, Ni, 0.02-3% Co, 25-45% Mn, and 8-20% Cr, is formed on a steel sheet by (5 to 50)g/m<2> coating weight per side. Then, a chromate film is formed on the above film by (10 to 200)mmg/m<2> coating weight expressed in terms of metallic Cr. At this time, cracking is allowed to occur in the Zn-X alloy plating film by means of chemical etching, etc. The density of cracks is regulated to <1000 pieces in the region of a visual field of 1×1mm at the surface of the plating. By infiltrating chromate into these cracks, the chromate film can be fixed firmly and weldability can be improved.

Filed: 1994-06-27
Abstract: PURPOSE: To improve measurement precision for a polymer electrolyte by connecting an ultrasonic oscillator to an outside wall of a cavity so that its vibration is transmitted in the radius direction to the axis of the cavity. CONSTITUTION: An ultrasonic wave oscillator is connected to an outside wall 38 of a cavity 31 so that its vibration is transmitted in the radius direction to the longitudinal axis of the cavity 31. A generated flow potential is transmitted to a control unit 22 via electrodes 34, 35 and an amplifier 56. This signal is processed by means of the control unit 22, and a measurement value is displayed by means of a measuring device 58. At the same time, a titrating action is carried out by using a duct 24. The ultrasonic wave oscillator 54 is turned on by means of the control unit 22 via a frequency regulation element, and as a result, ultrasonic wave vibration is introduced to a rinse liquid from an ultrasonic wave emitting element 43 and the ultrasonic wave oscillator 54.  When a frequency is properly regulated, an easily contaminated part in a sample vessel 30 such as an action area of a piston 33 and a floor 39 part can be washed thoroughly. Therefore, measurement precision and reproducibility especially are improved.

Filed: 1981-09-14
Abstract: PURPOSE:To obtain a strong power source without any environmental pollution by using a mechanism with the combination of a long frame and a push link to give force to promote the dynamic work. CONSTITUTION:A pulley 21 is connected to a prime mover via a belt, and a pulley 4 is connected to a driven machine via a belt. When the pulley 21 is rotated, a push link 14 is pushed by a shaft 18 fast fixed on a disk 20. Thereby, a wheel 19 is pushed to a central shaft 24 by a long frame 15, and a shaft 3 is pushed by a bearing 11 for rotating a disk 1. At this stage, because of the difference of the essential function of the wheel 19 from basic parts 6, 7, and 22, the wheel 19 works more dynamically than parts rotating at fixed positions. This construction permits to strengthen an output higher than an input for operating the driven machine.

IPC: H01L31/107
Filed: 1978-11-27
Abstract: PURPOSE: To reduce the diffusion process while eliminating any guard ring by making the thickness at the center of the epitaxial layer positioned under the pn- junction less than those in other parts in the formation of the junction on the layer grown on a semiconductor substrate.  
     CONSTITUTION: An n-type InP substrate 9 is projected only at the center by a mesa etching while a layer 10 of n-type InGaAsP or InGaAs is allowed to grow epitaxially on the entire surface. Then, a p-type region 3 is formed in the layer 10 by diffusion or ion injection corresponding to the projected area and a pn-junction is produced on the interface with the layer 10. Otherwise, in stead of the mesa etching of the substrate 9, the center of the epitaxial layer 10 may be etched deep. Then, the entire substrate is covered with an inductive material layer 7 and a window is given on the region 3, where an electrode terminal T 1  is mounted extending over the film 7 while an terminal T 2  is mounted on the back of the substrate 9 through an electrode 2. This reduces dark current and the junction capacity, making the device ideal for avalanche photo diodes very small in the light detecting diameter.
