Title: Display device
Inventor: KAWACHI AKIHIKO
IPC: G02F1/1335
Filed: 1988-03-03
Abstract: PURPOSE:To obtain a black-and-white display at low cost by placing one sheet of sheet or film of PVA made by a flow extending method on the front or the back face of a liquid crystal cell, or both its sides. CONSTITUTION:An incident light 1 passes through a polarizing plate being a polarizer 2 and goes to a linearly polarized light, and passes through a liquid crystal cell being a display use panel 3. When a voltage is not applied to the display use panel 3, a passing light goes to a circularly polarized light, and when it passes through a film 4 or a sheet which goes to a phase plate for optical compensation, it returns to its linearly polarized light. Finally, said light passes through a polarizing plate being an analyzer 5, but since a polarization axis of the analyzer 5 is vertical to the polarizer 2, light does not pass through. Accordingly, a complete black display is obtained. When a voltage is applied to the display use panel 3, the incident light remains as a circularly polarized light even if it passes through the polarizer 2, the display use panel 3 and the PVA (polyvinyl alcohol) film 4, and passes through the analyzer 5, therefore, a complete white display is obtained.

Title: Method and circuit for service detection
Inventor: FRANK COLIN D
IPC: H04W16/24
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To surely detect the availability of a CDMA(code division multiple access) service with a simple circuit constitution. SOLUTION: A radio telephone 121 uses a service detection circuit 125 which measures the energy of self-correlation of a reception composite CDMA signal and uses a different time delay for each measurement of the energy and is provided with at least one chip rate detector 109. A threshold detection circuit 127 couples measured energies, and the circuit 127 discriminates that the service is available of coupled energies exceed a threshold, but the circuit 127 discriminates that the service is not available if they don't exceed. Chip rate detectors 109 are coupled in parallel to be able to simultaneously measure the energy of self-correlation of the reception composite CDMA signal, or a single chip rate detector 109 can measure the energy of autocorrelation of the reception composite CDMA signal in series.

Title: Character generating method
Inventor: TOYODA TADASHI
IPC: G09G5/24
Filed: 1992-03-09
Abstract: PURPOSE:To prevent the occurrence of a phenomenon where one part of a character is lost owing to the recovery shortage of a line width caused by the relationship between a reduction rate and a dot size, when a character is generated in a stroke dot method. CONSTITUTION:A negative width compensation flag, showing a reversely stored stroke because of the narrower line width than a standard value, is added to the pattern data of a pattern memory 1, and a negative line width compensating device 11 is interposed between a compensating adder-subtractor 6 and a stroke dot operating device 7. Even if the stroke, which is reduced by a multiplier 5 and is reversed to a negative line width recovery treated output by the compensating adder-subtractor 6, is left as it is, the negative line width compensator 11 detects the stroke referring to a negative width compensation graph, and forms a state existing no reversed stroke by performing a compensating processing for the left reversed stroke so as to send the stroke to the stroke operating device 7 after offsetting the stroke through a following stroke. The output is converted to a full dot signal by a converter 9 so as to be printed out through a printer 10.

SOLUTION: In a molding device P, a molder Q molds molded matters F. Since recessed parts 4c are provided so as to adhere the molded matters F to one split mold 2 of a mold 1, with which the molded matters F are molded, all the molded matters F adhere to the one split mold 2 through the engagement with the recessed parts 4c. The one split mold 2, to which the molded matters F have adhered, is transferred above a molded matter receiver S in the next process so as to cut off and finish the molded matters F, which are transferred with a molded matter releasing device R from the one split mold 2 onto the molded matter receiver S, with a separating finisher T by one shot into molded articles A and burrs. An annular and conical sprue passage makes it possible to charge through a large number of sprues directly into respective molding cavities, resulting in realizing a multi-cavity molding.

Title: Picture quality controller of copying machine
Inventor: NARUSE KATSUHIKO
IPC: G03G15/08
Filed: 1983-03-26
Abstract: PURPOSE:To improve the responsibility of picture density control not only by adjusting the toner density of a developer, but also by controlling the revolving speed of a developing roll. CONSTITUTION:When picture density decreases below set density by some extent, a controller A13 applies a voltage higher than a reference voltage to a motor 5, whose revolving speed increases. Therefore, the revolving speed of the developing roll 2 also increases and the amount of the developr 8 supplied to a developed area on the surface of a photosensitive body increases to make the picture density higher. Simultaneously, a controller B14 engages a motor 16 with a toner feeder 11 through a clutch 12 and toner is supplied to increase the toner density of the developer, increasing the picture density. Then, the revolving speed of the developing roll 2 is returned to a reference speed when the toner almost reaches the developed area of the photosensitive body to hold the set picture density.

Filed: 1992-03-10
Abstract: PURPOSE:To always discriminate a demodulated base band signal in a maximum aperture part of an eye by measuring the variance of the eye at a prescribed timing of the output of an FIR filter and controlling the tap coefficient of the FIR filter so that the variance value is minimum. CONSTITUTION:An FIR filter 1 whose tap coefficients ho to hm are variable filters the demodulated base band. A variance measuring part 2 measures the variance of the eye at each prescribed timing of the output of the filter 1. A control part 3 controls tap coefficients ho to hm of the filter 1 in accordance with the variance value of the output of the measuring part 2. Thus, a code is always discriminated in the optimum state even if the position of the maximum diameter part of the eye is varied by the change of the transmission characteristic.
