Title: Linearizer
Inventor: OBATA YOSHIHIRO
IPC: G01R15/00
Filed: 1978-08-04
Abstract: PURPOSE: To enhance the accuracy with the use of a smiple and inexpensive construction by generating the counted value of a counter, which is operative to linearly count when an input signal value becomes coincident with the counted value of a non-linearly countable counter.  
     CONSTITUTION: A hundredfold counter 4 and a programmable n-fold counter 10 start their counting operations in response to the output pulses of an oscillator 3 with the aid of a control circuit 11 so that the counter 10 acts as a counter for counting the value which is stored in the zero address of an ROM 9. The counters 4 and 10 generate one pulse, when they finish the counting operations of the count numbers set therein, and start again the counting operations of the initial values. The outputs of the counters 4 and 10 add and subtract one pulse to and from the content of a summing counter 5 and a subtracting counter 2. When the number of the input pulses of the counter 5 reaches a preset value as a result of the repetitions of those values, an address counter 8 generates one pulse to increase the content one pulse, and the addresses of the ROM 9 are shifted to the next so that the counter 10 is made to act as the counter of the fold, which is stored in the counter 10.

Title: Deaeration packaging bag and packaging method
Inventor: KAI HISAO
IPC: B65D81/26
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain the state of sterilization that is much more satisfactory with decline of temperature at the surface of contents prevented by a method wherein a deaeration part is provided at a weld part on a bag mouth, and an incomplete weld part is made weaker in welding strength than vertical weld parts and the weld part on the bag mouth and separable in accordance with rise of internal pressure. SOLUTION: The number of deaeration part 3 may be one, or two or more for one weld part 2 on a bag mouth. An incomplete weld part 6 is provided at the inside of the bag mouth weld part 2. The incomplete weld part 6 must be made with the bag mouth welded airtightly and there should be no omission in welding. Although the incomplete weld part 6 is virtually welded completely, it is weak in welding strength and must be separated easily when internal pressure rises with a sealed bag heated by microwave heating. Namely, welding in such case must not be such that a film, being a bag material, is torn up. As heating progresses and internal pressure in the bag exceeds a specified level, the incomplete weld part 6, weaker in welding strength as compared with other parts, separates, and water vapor is discharged through the deaeration parts 3 provided at the bag mouth weld part 2.

Title: Preparation of electric conductive structure
Inventor: KAJI ISAMU
IPC: C08J5/04
Filed: 1985-05-02
Abstract: PURPOSE:To ensure obtaining electric conductivity in such applications as floor materials where the surface is easily flawed, by packing a polymer material in the opening space between the meshy solid gratings of a loose thick fabric which consists of electric conductive fibers and molding it. CONSTITUTION:A powder or liquid polymer material or its precuser is packed into the opening space in the meshy solid gratings of a loos thick nonwoven fabric prepared by using at least partly electric conductive fibers such as copper- absorbed fibers and then molded. As the nonwoven fabric forms three dimensional conductive meshy solid gratings, the electric conductive fibers remain continuous in the structural molding even if its surface has been damaged by friction, scratching, cutting, washing and so on and the electric conductivity of the molding is therefore not lost and the excellent anti-static characteristics is kept.

Title: Optical disk
Inventor: OTA YASUHIRO
IPC: G11B7/24
Filed: 1987-04-20
Abstract: PURPOSE:To attain <=0.5mus erasing time by providing a thin film consisting of specific elements adjacently to the boundary face of a recording medium. CONSTITUTION:The thin film consisting of at least one element among the element group consisting of respective elements of Y, Zr, Sc, Ru, Re, Gd, Tb, Dy, Ho, Nd, Er, Tm, Lu, Pr, La, and Sm is provided adjacently to at least one boundary face of the recording film. Erasure of the information of an optical disk is executed by projecting an energy beam to the optical disk and transferring the state of the recording film of the optical disk from the amorphous state to the crystalline state. Formation of crystal nuclei and growth of crystals by migration of atoms. are necessary at the time of transferring the amorphous state to the crystalline state in such a manner. Crystallization of the recording film arises from the boundary face of the recording film toward the central part of the recording film. The thin film is, therefore, provided on at least one boundary face of the recording film so that the thin film plays the role of the crystal nuclei. The erasing time from the amorphous state to the crystalline state is thereby shortened and the erasure at, for example, <=0.5mus is attained.

IPC: H03J3/28
Filed: 1987-04-20
Abstract: PURPOSE:To attain effective tracking adjustment by correcting the capacitance characteristic of a varactor diode of a main tuning circuit in response to the increasing region change in a channel selection voltage through the provision of a voltage variable circuit. CONSTITUTION:An antenna circuit is formed by a main tuning circuit 1 and an auxiliary tuning circuit 4 using varactor diodes 2, 6 respectively as variable tuning components and a voltage variable circuit 7 is connected to the circuit 1.

Thus, the deficient capacitance of the diode 2 is corrected and the change in the combined capacitance is made small to prevent the deterioration in the linearity of the capacitance characteristic and the effective tracking adjustment is attained by the combined capacitance by the circuits 1, 4.

Title: Satellite broadcast receiver
Inventor: ENOMOTO YOSHIMI
IPC: H04N5/44
Filed: 1994-04-07
Abstract: PURPOSE:To provide a device excellent in operability and in electric power saving concerning a satellite broadcast receiver where a pay broadcast decoder is incorporated. CONSTITUTION:When the power source of a TV receiver body is turned on and a detecting circuit 11 detects no external wave-detection signal input even if an external BS change-over switch 5 is at an external wave-detection signal input side, a control circuit 14 changes-over a wave-detection change-over circuit 3 to an internal wave-detection signal side. Thus, an original operation as a BS tuner is obtained without changing-over the change-over switch 5 and the operability is improved. The control circuit 14 turns on a power source supply switch 13 only when the change-over switch 5 is at the external wave-detection signal input side and also the detecting circuit 11 detects that the external wave-detection signal exists when the power source of the TV receiver body is turned off. Therefore, electric power is hardly comsumed in the BS tuner itself at the time of recording stand-by when the pay broadcast decoder 7 is used so as to conduct automatic recording in an external VTR so that electric power is remarkably saved.
