Title: Twin switch
Inventor: KURIHARA TAKASHI
IPC: H04B10/27
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To build an inexpensive and customized communication and broadcasting system with two pieces of fiber pairs which is capable of arbitrarily switching one point to another point with a two-core batch by constituting two sets of 1×n optical switches arranged in parallel in such a manner that the optical paths of both are synchronously selected. SOLUTION: Two-core constitution is formed by combining two sets of the 1×n waveguide switches within the same substrate in parallel. The optical path switching of optical signal transmission and reception is executed by using a pigtail type module of the 1×2 thermooptical twin switching. The three points of users 1 to 3 are connected via the 1×2 thermooptical twin switch module. The user 1 and the user 2 are able to make information exchange without having any changes at all from point-to-point when the heaters A to C of the twin switches are synchronously lighted. The user 1 and the user 3 are able to make information exchange without having any changes at all from point-to- point when the twin switches are changed over (B and D are synchronously lighted).

Title: Intrusion alarm unit for person
Inventor: KAWAGUCHI HIROTOSHI
IPC: G08B13/19
Filed: 1990-09-18
Abstract: PURPOSE:To prevent an alarm tone from being issued suddenly even when a person enters a detection area accidentally by issuing two kinds of barking of dog when measurement is being performed for constant time from a decision point and after the measurement is completed when an infrared detector decides the presence of the person. CONSTITUTION:When the person enters the detection area of the infrared detector 1 and a decision part 2 decides the presence of the person from temperature difference between a background and the dimension of an infrared radiator, an alarm part 3 issues the barking of the dog such as (uh...) as a warning tone, and simultaneously, a time measurement part 4 starts the measurement of a time from the decision point. When it is decided that the person is still present after the completion of the measurement for constant time, the alarm part 3 issues the barking of the dog (bow-wow) as the alarm tone. Thereby, it is possible to prevent the alarm tone from loudly ringing, which reduces erroneous recognition even when a person who is not an invader enters the detection area of an intrusion alarm unit accidentally.

Title: Ice making method and ice heat accumulator
Inventor: NAKAZAWA YUJI
IPC: F25B13/00
Filed: 1988-10-03
Abstract: PURPOSE:To make it possible to produce ice efficiently without enclosing an ice making container and a heat accumulator by bringing non water soluble liquid into direct contact with water in order to cool said water and generating slurry-like ice at the same time while agitating water. CONSTITUTION:A refrigerant compressed by a compressor 8 is condensed by a condenser 9 and liquefied therein. Then, it is vaporized in vaporizers 11and 13, then it cools oil O. The oil O is brought into direct contact with water W positioned above and exchanges heat efficiently by agitating motion. The water W is cooled uniformly so that it may turn into excess cooling state. When this excess cooling state is cancelled by the impact of air E, the water W is frozen into ice, thereby generating slurry-like fine ice in the water layer. This ice I is fed into a heat accumulator 3 from a communication pipe 4. This construction prevents the generation of refrigerant leakage and the drop in the ice making capacity induced by mixed air even when an ice making container 2 and the heat accumulator 3 do not comprise an enclosed vessel.

Abstract: PROBLEM TO BE SOLVED: To provide a function of detecting cutting or coming off from a sprocket of a chain to stop rotation of a sprocket. SOLUTION: Retchet teeth 7 are formed around on a part of circumference of a boss 2b of a driven sprocket 2. An arm 10 has a shaft 8 parallel with a rotation shaft 2a of the sprocket 2, an idle sprocket 11 on one of two rotation ends across the rotation shaft 8 and a fork hook 12 to be meshed with the ratchet teeth 7 on the other end. A coil spring 13 is wound around the rotation shaft 8 of the arm 10 to keep the idle sprocket 11 meshing with a chain 3 and to prevent the hook 12 on the other end from meshing with the ratchet teeth 7. When the chain 3 is cut, the idle sprocket 11 moves away from the track of the chain 3 and the arm 10 rotates clockwise to make the hook 12 of the arm 10 mesh with the ratchet teeth 7 of the driven sprocket 2. Rotation of the driven sprocket 2 is thus stopped.

Title: Production of coke
Inventor: NAKAJIMA HIDEO
IPC: C10B57/00
Filed: 1985-11-11
Abstract: PURPOSE:To reduce the variation in carbonization time and to efficiently and stably operate a coke oven, by controlling the amt. of charging coal, i.e., changing the amt. of the charging coal according to the properties of the coal. CONSTITUTION:A process for preparing coke comprising carbonizing coal, wherein the amt. of coal per carbonization chamber in a coke oven is calculated based on the data on the properties of charging coal which has been previously determined so as to attain a constant coal carbonization time and that the amt. of the charging coal is controlled so that the actual amt. of the charging coal is equal to the calculated amt. The amt. of the charging coal has been currently determined by mounting a measuring instrument in each hopper of a charging car or by measuring the weight of the charging car. In the current method, an exact amt. of the charging coal cannot be determined, because the amt. of the coal practically charged in the oven is determined by subtracting the amt. of the output coal from the measured amt. The control of the amt. of the charging coal based on the calculated amt. of the coal enables the realization of exact, rapid and safe operation of a coke oven.
