Title: Variable resonance circuit
Inventor: OKABE KAORU
IPC: H01P7/04
Filed: 1989-04-24
Abstract: PURPOSE:To make the size of circuit small and to improve the characteristic by forming a center conductor of a coaxial mode resonator to be hollow, inserting a variable reactance element in the inside of the hollow part so as to connect it with a resonator in parallel or series in terms of high frequency. CONSTITUTION:The length of a coaxial mode resonator 11 is l and the resonator 11 consists of a hollow center conductor 12 and an outer conductor 13 and a dielectric material 14, and a variable reactance element (variable capacitive element) 16 is contained in the inside of the hollow part of the conductor 12 and one tip 15 of the conductors 12, 13 is terminated with a short-circuit. Then the variable resonance circuit is formed between an external connection terminal 22 and the outer conductor 13 of the resonator 11 and the resonator 11 and the element 16 are connected in parallel in terms of high frequency. Thus, from the definition of a coaxial mode resonator whose termination is short-circuited, the resonator acts like a series resonance circuit at a frequency in which the length l is 1/2 waveform length and acts like a parallel resonance circuit at a frequency in which the length l is 1/4 waveform length. That is, the element 16 is contained in the inside of the conductor 12 to save the circuit space, the resonator 11 and the conductor 16 are connected in a short distance to make the size of the circuit small and to obtain an excellent performance.

Abstract: PROBLEM TO BE SOLVED: To apply an excellent decorative design to the inner wall face of a cage by providing an optical fiber tube provided on the back face side of a translucent member provided at the connection portion of multiple panel members constituting the inner wall face of the cage and a light source unit provided on the cage to feed light. SOLUTION: Both ends of one optical fiber tube 14 are connected to a light source unit 15 provided on a cage. When light is fed to one end of the optical fiber tube 14 from the light source unit 15, the optical fiber tube 14 located on the back face side of a translucent joint plate 10 (translucent member) on a side panel is illuminated.

When the color filter of the controller of the light source unit 15 is variously changed, the joint plate 10 is illuminated in various colors. The joint plate 10 and optical fiber tube 14 exert a large effect in decorative design.

Abstract: PURPOSE:To treat a liquid material contg. solid foreign matters such as ice sludge without taking out said foreign matters out of the system by providing a horizontal cylindrical filtration tank and a heating means, melting the solid foreign matters and permitting the melted material to pass through a strainer. CONSTITUTION:Crude petroleum oil contg. sludge enters a filtration tank 1 from a liquid inlet 11 in the direction of an arrow mark. When the oil passes through a filter element 3, the sludge together with other solid matters (if any) sticks to the outside of the filter element 3. The part of the filter element 3 having deposited solid matters is turned to the opposite side to the inlet of the liquid, where the solid matters are scraped off continuously by a scraping means 4 and fall into the bottom of the filtration tank 1. There, the solid matters are heated together with accompanying oil and melted and transformed to the liquid state. The crude petroleum oil contg. the melted sludge passes through the filter element 3 at the top of the heating means 5 and is discharged together with the crude petroleum oil supplied from a liquid inlet 11 from a liquid outlet. Unmelted solid matters settle to the bottom of the filtration tank 1 and are discharged when accumulated from a drain port 13.

Title: Retrieving device for microfilm reader
Inventor: YAMAGUCHI TAKU
IPC: G06F17/30
Filed: 1990-04-20
Abstract: PURPOSE:To prevent the film from being fed to the end due to an input miss of an address by stopping a feed of the film, when it is decided that an address of a target frame cannot be taken as an address of the film. CONSTITUTION:When the film is running, the running quantity from the head of the film and blip information are integrated, for instance, by a counter in a running quantity detecting means 126 and a blip detecting means 70, respectively, and by these new data, the contents of a memory means 110 are always rewritten. When a blip discriminating means 124 detects a target frame, based on the contents of the counter of the blip detecting means 70, rewriting of the memory means 110 is inhibited immediately, and by using this stored information, the film is fed in reverse to the target frame. In the case an address of the target frame is inputted exceeding a range of an address which it can take, it is discriminated by a coincidence/noncoincidence discriminating means 130. In such a way, even in the case of an input miss of the address of the target frame, the retrieval can be stopped on the way of retrieval.
