Title: Talking sound volume adjusting system for telephone set
Inventor: MORI TAKASHI
IPC: H04M1/76
Filed: 1987-05-13
Abstract: PURPOSE:To set an optimum speech level at all times by setting a gain of a reception amplifier to a prescribed value so that the speech sound volume is a preset value at the start or at the end of talking. CONSTITUTION:A gain control circuit 6 is provided, which varies the gain of the reception amplifier 3 to gain in response to the talking party thereby adjusting the sound volume. The gain control circuit 6, at the start or end of talking, resets the gain of the reception amplifier 3 to a predetermined standard value even when the sound volume adjustment during talking is any value. Thus, the gain level set in response to a talking party in the preceding use is restored always to the standard level at the succeeding talking. Thus, the optimum talking sound volume is set at all times.

Abstract: PURPOSE:To restart a processing without requiring a time when a trouble occurs, by writing always the data of a recording area in RAMs of both of dualizing systems. CONSTITUTION:The data of the recording area of sound information from a telephone exchange is written simultaneously in a RAM 102 and a RAM 105 from a central controller 100 through a data bus 106. If a trouble is detected in the controller 100 by a trouble detecting circuit 13, the detecting circuit 113 indicates switching between controllers 100 and 103. When receiving the switching indication, the controller 103 restarts the processing immediately and controls a disc control part 110 and a disc device 111 by a control part consisting of a RAM 104 and the RAM 105. Thus, a time is hardly required when the central controller restarts the processing.

IPC: G02F1/1341
Filed: 1994-05-27
Abstract: PURPOSE:To obtain a TN liquid crystal display panel having improved visual angle characteristics in which liquid crystal molecules are arranged in random directions without causing irregularity of display due to injection of the liquid crystal material. CONSTITUTION:A pair of transparent substrates 1 are disposed facing to each other with a space in between, into which a liquid crystal material 6 is injected to produce a TN liquid crystal display panel. The panel contains liquid crystal molecules distributed at random with small intervals and shows improved visual angle characteristics. In this method, an oriented film such as polyvinyl alcohol, polyvinyl butyral, or polymethyl methacrylate is used so that the arrangement of liquid crystal molecules on the interface of the oriented film is made isotropic in the plane of the transparent substrates by heat treatment. After the liquid crystal material 6 is injected at a room temp., heat treatment is performed to eliminate display irregularity 8 due to injection of the liquid crystal material 6. The same effect can be obtd. by applying a mixture of a polymer orienting material and a polymer soluble in water or an org. solvent to form a oriented film and then removing the polymer soluble in water or the org. solvent by washing to roughen the surface of the oriented film.
