Title: Digital broadcast reception system
Inventor: ABE MIKITO
IPC: H04B1/16
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To enable a user to always listen to reproduced sounds of a broadcast wave having a high priority even in the case of simultaneous start of a specific program with plural broadcast waves by preferentially outputting the specific program which is broadcast by a broadcast having a high priority base on designation of listening of the specific program to be broadcast and the precedence. SOLUTION: If it is discriminated that RDS broadcasting doesn't support a specific program, it is discriminated whether DAB broadcasting supports the specific program or not and if it supports the specific program, it is discriminated whether the specific program is started with the DAB broadcasting or not. In the same manner, if it is discriminated that the DAB broadcasting doesn' t support the specific program, it is discriminated whether the RDS broadcasting supports the specific program or not and if it supports the specific program, it is discriminated whether the specific program is started with the RDS broadcasting or not. Consequently, broadcasting having a low priority is taken into consideration only when it is discriminated that the specific program is not supported by broadcasting having a higher priority.

Title: Cryogenic freezer device
Inventor: KO NAOKI
IPC: F25B9/00
Filed: 1990-05-23
Abstract: PURPOSE:To provide a compact freezer device having a high freezing efficiency by a method wherein gaseous refrigerant is composed of hydrogen gas or the like and a small container containing metallic hydride therein is communicated with a high temperature end part of a pulse tube through a hydrogen filter. CONSTITUTION:Gaseous refrigerant flows from a pulse tube 8 into a small container 12 during a compression stage, a balanced hydrogen pressure is increased in respect to an expansion stage and absorbed. During an expansion process, the gas is forcedly discharged from the small container and an interior part of the small container is low pressurized and then the gas is discharged from the metallic hydride. Thus, an amount of absorbing or discharging is added to the pulse tube only by an amount of absorbing or discharging of the gaseous refrigerant and then an entire volume of the device is substantially increased. Accordingly, the pulse tube can be made small by an amount of increasing in a substantial volume. Since the small container is separated from the pulse tube, heat generated through compression in the small container can be prevented from being transmitted to the pulse tube and an efficient heat release from the small container to the outside part of the device can be attained. Thus, a freezing efficiency is further increased by an amount of efficiency improvement of heat release at the cryogenic freezer device.

Filed: 1983-07-22
Abstract: PURPOSE:To read a data code following a synchronizing bar code based on the stored synchronizing timing, by sweeping and reading a synchronizing bar code and store it as the reference synchronizing timing. CONSTITUTION:When a bar code label 94 is set at a regular position, four bits of the first bar code photodetecting signals 42-45 are read to the bar code photodetecting signals 42-51 and simultaneously with generation of the 1st line sweep start signal 52. These four bits are stored to a synchronizing signal memory circuit 105. Then bar code read timing signals 59-62 are produced based on the stored signal interval time and simultaneously with generation of the 2nd line sweep start signal 53. Then signals 46-48 which receive light during the 2nd line sweep mode are read, and data codes 67-69 are stored to the circuit 105. Furthermore the bar code photodetecting signals are read in the timing of the signal interval time stored in the circuit 105 also in the 3rd line sweep mode like the 2nd line sweep mode. Thus the data codes 70-72 are decoded.
