Title: Liquid crystal driving device
Inventor: KOBAYASHI MAMORU
IPC: G02F1/133
Filed: 1991-06-21
Abstract: PURPOSE:To easily reduce the offset voltage between the input and output of the data-side driving circuit of an active matrix liquid crystal panel without any external control. CONSTITUTION:The common potential of a sampling capacitor 113 is selected by a changeover switch 115 between two voltage values and one potential is an output at the time when the other potential is inputted to a 2nd buffer 116. At this time, the common potential is the output potential of the 2nd buffer at the time of sampling and the input potential of the 2nd buffer at the time of output. Consequently, the offset voltage between the input and output can be reduced by cancellation between the offset voltage of the output buffer 114 and the offset voltage of the 2nd buffer.

IPC: H04B14/04
Filed: 1988-06-17
Abstract: PURPOSE:To eliminate a noise in the nonaudio section of a voice by transmitting the voice after inserting a specific pattern to the nonaudio section of the voice at a transmission side, and eliminating the output of a decoder for the section from which the specific pattern is detected at a reception side. CONSTITUTION:An analog voice signal impressed on an input terminal 1 is encoded by an encoder 3 at every frame, and is sent to a data inserter 22. The inserter 22 substitutes the specific pattern not used in the encoder 3 for an encoded signal corresponding to the nonaudio section detected by a nonaudio detector 21. A digital signal from the inserter 22 generated in such way is modulated 4, and transmitted. Meanwhile, a reception signal is detected 7, and the decoder 9 regenerates an original voice signal, and sends it to a signal suppressor, 24. A nonaudio detector 23 detects the pattern same as or similar to the specific pattern at every frame of the signal as a nonaudio pattern. The signal suppressor 24 eliminates a decoded signal from the decoder 9 from the section where nonaudio is detected by the detector 23, and sends it to a voice signal output terminal 10.

Title: Manufacturing of adiabatic wall body
Inventor: TANIDA TOSHIHIKO
IPC: F16L59/05
Filed: 1978-12-04
Abstract: PURPOSE:To provide adiabatic wall panel having uniform strength and adiabatic property without necessity of after-treatment in a method that a melt liquid material of adiabatic substance is poured into a frame whose upper side is opened and obliquely positioned, and is repositioned in a horizontal status after pouring the said liquid which will foam thereafter to complete wall panel with cured adiabatic layer. CONSTITUTION:Wall panel blank 1 is first inclined by angle theta1, and melt of foaming insulation substance is poured on the inner bottom 1a of blank 1 from nozzle 4. When the melt dropped to a point 7 just under the nozzle 4 flows down to a point 8 which has nearly equal distance l2 from flange 3 to that l1of the point 7,  the pouring from nozzle 4 is terminated and the blank 1 is reprositioned to horizontal status. As the melt is foaming, its upper surface is gradually pressed by press  member 9 so as to stretch the foaming melt until it reaches at inner faces of both  flanges 3 and to fill up whole inner bottom 1a uniformly. This process can prevent insulation substance from its scattering away, and contributes to make excellent  adiabatic wall panel with uniform adiabatic feature and strength as a whole

Title: Magnetizing method of magnetic material
Inventor: OOMURA YOSHIMOTO
IPC: G11B5/325
Filed: 1982-08-31
Abstract: PURPOSE:To form magnetic poles with a small space to a ferromagnetic material of high coercive force, by shifting in steps and intermittently a magnetic head device to a magnetic material with each magnetic pole array pitch (p) in a single direction of a magnetic pole pattern and reversing the current polarity for each shift of the magnetic head device by the pitch (p) for magnetization. CONSTITUTION:When the magnetic pole array pitch (p) of a magnetized pattern is set at about 400mum, for example, it is sufficient to set (a) and (g) at about 150mum and 250mum with the depth (d) set at about <=500mum respectively. A magnetic head device 10 is successively shifted in steps in a fixed direction (arrow A) with each magnetic pole array space (p) to a ferromagnetic material 1, and at the same time the direction of magnetizing current is reversed for a magnetic coil 15 for each step shift of the device 10. Then the polarities of magnetic poles energing at arm parts 13 and 14 of magnetic cores are successively reversed, and the magnetic poles of same polarity are formed at the same part of the material 1. For a magnetized pattern recorded to the material 1, the poles N and S are distributed alternately along a fixed direction A with a fixed length (p) defined as the array pitch. Therefore each magnetic pole is magnetized with equal polarity for each intermittent shift of the device 10. In this way, the magnetization is never attenuated but increased for the magnetized magnetic poles. Thus, the efficiency of magnetization is improved.
