Title: Power semiconductor device
Inventor: ISHIBASHI CHIHIRO
IPC: H01L23/44
Filed: 1990-11-02
Abstract: PURPOSE:To improve the cooling efficiency of a power semiconductor device by providing cooling pipes penetrating electrodes of the device to bring coolant into direct contact with the inside of the device and radiate the absorbed heat outside. CONSTITUTION:A power semiconductor device has copper electrodes 3 and 4. Alloy plates 6 and 7, extending from sides of the electrodes, are bonded to the upper and lower ends of an insulating package 5. A semiconductor substrate 1 and a heat buffer 2 are housed in the package. The alloy plates 6 and 7, forming part of electrodes, are penetrated by cooling pipes 9 and 10, which have many fins 11 on their ends and hold coolant to be charged into the insulating package 5. The coolant directly cools the inside of the device and radiates the absorbed heat through the fins 11. As a result, the cooling efficiency is increased, and thus the device sized is reduced.

Title: Method for suppressing formation of trihalomethane
Inventor: YAGI YASUYUKI
IPC: C02F1/78
Filed: 1985-12-27
Abstract: PURPOSE:To effectively remove trihalomethane precursors with a small amt. of the ozone to be injected by subjecting feed water to an ozone treatment in the presence of an iron salt, converting the dissolved iron salt to iron hydroxide and subjecting the water to a solid-liquid sepn. CONSTITUTION:The iron salt is injected into the feed water prior to chlorination in the stage of injecting the chlorine to the taken in river water to exterminate the bacteria in the feed water. The feed water is subjected to ozone oxidation in the presence of iron salt after pH of the feed water is adjusted to 3-5. The pH of the treated liquid is then made neutral to convert the iron salt in the liquid to the iron hydroxide and such liquid is subjected to the solid-liquid sepn. As a result, the amt. of the ozone to be injected is considerably decreased and the trihalomethane forming power is considerably decreased. The irin salt added to the water in the ozone oxidation state is converted to the iron hydroxide in the neutralization stage to adsorb and co-deposit the remaining trihalomethane precursors and therefore, the flocculation and settlement are efficiently executed and the frequency of exchanging activated carbon is made twice longer. The cost of maintenance and control during the installation of the activated carbon is considerably reduced.

IPC: G01R31/00
Filed: 1988-11-25
Abstract: PURPOSE:To speed up an output characteristic test by operating a self-operating clock incorporated type circuit forcibly with an external clock of higher frequency than a self-operating clock when a wait time is entered. CONSTITUTION:The self-operating clock incorporated type circuit is so constituted that a step n4 wherein a relay switch 6 is turned on so as to apply an external clock from an oscillation circuit for shortening the wait time to the self- operating clock incorporated type circuit 2 is added between steps n2 and n3. In this step n4, the relay switch 6 is turned on. Then, the external clock from the oscillation circuit 10 is inputted to the self-operating clock incorporated type circuit 2 through a driving circuit 8. Consequently, the self-operating clock incorporated type circuit 2 operates in response to the external clock. When the frequency of this external clock is set (n) times as high as, for example, an internal clock, the wait time is shortened to t/n.
Patent JP-S62195868-A (JP)
Title: Jack
Inventor: DENISU EMU BAAROOZU
IPC: H01R24/46
Filed: 1986-12-13
Abstract: The disclosure is directed to a coaxial jack having a make before break switch in a first conductive path between signal-in mechanism and first signal-out mechanism. The switch is functioned on insertion of a plug in second signal-­out mechanism which forms a second conductive path between said signal-in mechanism and said second signal-out mechanism. The jack not only matches impedances with the coaxial cables, but does so by equalizing inductive and capa­citive reactances and by maintaining an impedance match at each structural support between a conductor in the jack and the housing of the jack. The housing of the jack is modular thereby providing superior versatility with respect to various configurations and applications.

Filed: 1988-11-25
Abstract: PURPOSE:To prevent the generation of abnormal vibration more surly and to prevent the vertical vibration of a vessel by providing a decision device whereby it is decided that articles of washing are equally held in the vessel when a detection current reaches a setting value and it is decided that they are not equally held when it does not reach the setting value. CONSTITUTION:After a current flowing to a motor 8 is detected by a detecting device 11, it is inputted into a controlling device 10 through an A/D converter 12. The detection current inputted in this way is caught by the controlling device 10 after a time, t, where it elapses a little after a dehydrating operation is started. At that time, if the detection current I reaches a setting value I1 after decreasing, it is decided that articles of washing are equally held in an inner vessel 4, and if not so, it is decided that they are not equally held in the inner vessel 4. Furthermore, on the basis of this decision, when the articles of washing are equally held in the inner vessel 4, the dehydrating operation is continued. If not so, the dehydrating operation is intermitted and then an untwisting operation is started.

Title: Card collecting device
Inventor: MATSUMOTO MASAHIRO
IPC: G07B15/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To easily confirm whether or not a card is inserted into the card collection device and the kind of a deposit for the inserted card. SOLUTION: When a lift ticket 1 is inserted into the reader writer 2 of a lift ticket collecting machine 10, a main control part 3 makes a display part 4 start displaying the insertion of the card. After it is checked whether the ticket is genuine or not, a bill pay-back part 6 returns the deposit and when the reception of the bills is detected, the main control part 3 instructs the display part 4 to erase the display of the card insertion. Consequently, it can easily be confirmed whether or not the card is inserted and an illegal request to pay back without card insertion can be coped with. Further, the amount of the deposit is read out and displayed instead of displaying whether or not the card is inserted, and then even when there are plural amounts of deposits and the device gets out of order, the amount of money to be paid back can easily be confirmed, so that measures can speedily be taken in case of the fault.

Abstract: PURPOSE: To be used as a brake hose in a severe application area by embedding reinforcing yarns in a wall of the hose simultaneously at the time of winding it around a core in a crosshead, and heating an original compound at its vulcanizing temperature in the crosshead at the time point of embedding the yarns in a wall of the hose. CONSTITUTION: Reinforcing yarns follow a rotating motion of a cross mandrel 4. And, the yarns are automatically wound on a core 7 continuously moved in a direction of an arrow in an axial direction after outputting from its end face side opening 11. The yarns output from the opening are embedded in a melted state or pasty material.
