Title: Television system discriminator
Inventor: UCHIYAMA SHINICHI
IPC: H04N9/79
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To reduce a discrimination time at the time of starting power supply in a television system discriminator that automatically discriminates whether a subcarrier frequency of a chrominance subcarrier signal is about 3.58 MHz or about 4.4 MHz in a recording circuit of a VTR. SOLUTION: A tank circuit 14 of a television system discrimination circuit 50 has a resonance circuit that selects and sets a 1st resonance frequency higher than a subcarrier frequency of a low frequency conversion chrominance signal or a 2nd resonance frequency lower than the subcarrier frequency of a low frequency conversion chrominance signal, and a 90-degree phase shifter 15 shifts a phase of a signal outputted from the tank circuit 14 by 90 degrees.  A phase comparator 16 compares a phase of the low frequency conversion chrominance signal with a phase of the shifted signal and outputs a phase error signal to a system discrimination circuit 18 via an LPF 17, the system discrimination circuit 18 immediately discriminates whether the subcarrier frequency of the chrominance subcarrier signal included in a composite video signal to be received is about 3.58 MHz or about 4.43 MHz based on the signal from the LPF 17.

Filed: 1985-05-30
Abstract: PURPOSE:To make it possible to cover both the front and the back parts with the same outer skin material, by applying an adhesive on a cushion body or the outer skin material and by adhering the cushion body with the outer skin materials by pressing them in a press mold. CONSTITUTION:A cushion body 4 consists of a back resting part 4a and side supporting parts 4b rising frontward from both right and left sides of the back resting part 4a and thus forms a down-and-up shape. An adhesive 5 is applied on the front surface of the cushion body 4 to adhere an outer skin material 9 with the cushion body 4. Adhesion of the unnecessary parts and uneven adhesion are prevented by temporarily deactivating the adhesive strength of the adhesive after coating. The cushion body 4 coated with the adhesive is inserted into the opening part of the lower end of the outer skin material 9. The front part 1 of the outer skin material9 and the front side of the cushion body 4 are adhered together with the adhesive by pressing them in a press mold. When a hot melt adhesive is used, the press is carried out by heating the adhesive. It is possible thereby to adhere tightly the outer skin material 9 with the cushion body 4 along the down-and-up shape and to remove remarkably the limitation of the design.

Abstract: PROBLEM TO BE SOLVED: To suppress the doping of a non-doping layer with beryllium by avoiding the reevapolation of an evapoating material which is produced from a molecular beam cell for molecular beam epitaxial and adhered to the cell and the periphery thereof. SOLUTION: A shutter 5 is two-stage structured so that the reevaporation of the evaporated material adherent to the first stage shutter may be avoided by the second stage shutter. Accordingly, the reevaporation of the evaporated material adherent to the second stage shutter can be neglected so that the second stage shutter may not reach a high temperature since it is not directly radiated from a crucible 1. Through these procedures, the pollution of a non- doped layer due to reevaporated dopant can be avoided.
