Title: Production of phase difference plate
Inventor: TABATA HIRONORI
IPC: G02F1/1335
Filed: 1992-07-13
Abstract: PURPOSE:To provide the method which can easily produce the phase difference plate having the phase difference compensation performance and visual field angle characteristic uniform and excellent over approximately the entire area of a film. CONSTITUTION:The phase difference plate is produced by transversely uniaxially stretching a polysulfone film by using a tenter stretching machine, molding the stretched film p in such a manner that the sectional shape in the longitudinal direction of the film is a waveform and gripping both transverse ends of the film P in the state of maintaining the waveform shape, then subjecting the film to a heating treatment while controlling the variations of the reduction rate at every 1/2 pitch of the waveform to keep the fluctuations within a + or -25% range thereby reducing the longitudinal direction of the film. Since the film P is subjected to the heating treatment by gripping both the transverse ends of the film in the state of maintaining the waveform shape, the partial shrinkage (neck-in) in the transverse direction of the film P does not arise. In addition, the variations of the reduction ratio at every 1/2 pitch of the waveform are controlled within the + or -25% range and the unevenness of the phase difference values is therefore lessened.

Title: Method and device for manufacturing tin oxide film
Inventor: SATO KAZUO
IPC: G02F1/1343
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To make uniform film thickness or the like, without being affected by fluctuations in wind and air pressure around a device by mixing gas containing tin tetrachloride and gas containing water in advance and discharging the obtained gas essentially containing the tin tetrachloride and water by turbulence, and forming a tin oxide film on a glass substrate. SOLUTION: A gas containing tin tetrachloride and water is discharged onto a glass substrate that travels in one direction essentially by turbulence, and a tin oxide film is formed by the reaction with tin tetrachloride enriched water occurring on a high-temperature glass substrate. In this manner, since turbulent gas is used for manufacturing the tin oxide film, air current balance cannot be lost even if wind and air pressure around the device fluctuate, thus obtaining a tin oxide film with a uniform film thickness and crystal particle diameter. More specifically, when the flow of gas is a laminar flow, eddies or the like are generated due to the influence of fluctuation factors and the tin oxide film tends to become nonuniform. However, when it is a turbulent flow, the influence is suppressed.  In this manner, the obtained tin oxide film is uniform to the extent that it can be used as an electrode for a solar battery.

Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To increase the speed for starting up main output and to improve efficiency by closing a switch for dummy resistor when a DC-DC converter starts operating and at the same time opening it when the converter stops operating using a switching circuit. SOLUTION: In a circuit, a switch Tr1 for a dummy resistor RD is connected in series with a dummy resistor RD between the terminals of a smoothing capacitor C1, a switch rla is fumed on when RCC operates and a coil RL receives a remote on signal from a load, a switch Tr1 is turned off and a main output mode is selected, and resident output and main output are supplied. On the other hand, when the coil RL receives a remote off signal, the switch Tr1 is formed off and a resident output mode is set to turn off the switch rla, and only resident output is supplied and at the same time main output is stopped. However, the residual charge of the smoothing capacitor C1 cannot be consumed due to the switch Tr1 for dummy resistor RD, thus speeding up the start of main output and improving efficiency.

Title: Paper detecting circuit for optical character reader
Inventor: HIROSE TSUNEO
IPC: G06V10/10
Filed: 1981-11-20
Abstract: PURPOSE:To reduce the required amount of a picture storage memory, by providing a circuit omitting unnecessary picture information from a picture data at the out side of a designated reading region on paper. CONSTITUTION:A binary signal converted at a binary circuit is shifted at a shift register 15 and inputted to an AND circuit 18 and an NOR circuit 19. Since outputs of the circuits 18, 19 are inputted to J, K terminals of a JK FF20, the output of the FF20 is not inverted if a plurality of bits of binary signals are not consecutive, and the preceding state is kept. Thus, the FF20 is not changed at balck parts where only several bits are consecutive such as the character pattern, and changed only when a lot of bits are consecutive such as side and ridge of paper, then characters on paper can be regarded as omitted. When no reading field signal 14 exists, an input signal 24 to a data compression circuit can be obtained through an AND gate 21 and an OR gate 23. A shift register 16 corrects the delay in the circuit and when the signal 14 exists, a signal 24 is obtained through circuits 22 and 23.

Filed: 1988-07-27
Abstract: PURPOSE:To output a clamp pulse with an optimum pulse width corresponding to a synchronizing signal by controlling the clamp pulse width depending on the clamp width data commanded by a microcomputer. CONSTITUTION:A microcomputer 11 outputs a control signal with a clamp width as a clamp width data to a comparator 13. On the other hand, a counter 12 counts up a clock pulse 15 of a prescribed period while a clamp pulse 2 is at a high level and when the clamp pulse 2 goes to a low level, the counter 12 is reset. Thus, the clamp width data and the countup data are both given to the comparator 13, which compares them and outputs a reset signal when they are coincident to reset a flip-flop 14. Thus, the clamp pulse with an optimum pulse width with respect to a synchronizing signal is generated.
