Patent JP-H0846504-A (JP)
Title: Relay
Inventor: NIWA MASAHISA
IPC: H03K17/78
Filed: 1994-07-29
Abstract: PURPOSE:To obtain a relay suitable for a self-hold circuit by forming a switching circuit with a photoelectric element and a MOSFET. CONSTITUTION:When an alarm pulse signal of a sensor is given to input terminals P1, P2, an input side light emitting diode 1 is lighted and a photoelectric element 21 receiving the light generates a phtoelectromotive force, a MOSFET 22 to which the photoelectromotive force is applied between a gate 22g and a source 22d is turned on and the part between the drain 22d and the source 22s is conductive. Then a load current is supplied from a power supply E and then an alarm buzzer Bz starts ringing and the load current flows to an output light emitting diode 3, which is lighted, the photoelectric element receiving the light generates successively the photoelectromotive force to self- hold the MOSFET 22 to be the ON state and then the buzzer Bz keeps buzzing. Moreover, when a normally-closed switch S is restored manually and open, the diode 3 is not lighted and the photoelectromotive force of the photoelectric element 21 is lost and the MOSFET 22 is turned off and released from the self-holding state and the buzzer Bz is stopped for buzzing.

Title: Production of wound coating material
Inventor: KOMATSUZAKI SHIGERU
IPC: A61F13/02
Filed: 1989-07-11
Abstract: PURPOSE:To obtain a wound coating material which accelerates clotting and scabbing by stirring and heating a raw material-contg. liquid to form a uniform soln., stirring and cooling this soln. to form the dispersion gel in which the raw material-contg. gel particles are dispersed and lyophilizing this gel in the presence of a frozen state control agent. CONSTITUTION:After cyclohexane is added to the compsn. of benzene and silver polysulfadiazine, the mixture is stirred until the uniform soln. is prepd. at the temp. at which the soln. does not structurally change without evaporating the benzene. This soln. is cooled under stirring to room temp. to prepare the dispersion gel 7. For example, a nylon mesh 3 is extended in a mold 8 and the dispersion gel 7 is cast in the state of the room temp. into the mold 8 and is lyophilized as it is. The freezing progresses from a rack 42 side and the free benzene 33 between the dispersion particles 4 crystallizes earlier. The crystallization progresses gradually from above to below so that a fibrous structure is formed on a wound surface side 31 and a network structure in the inside 30. The coating material included with pores in the three-dimensional structure is obtd. by the evaporation of the benzene.

Title: Superconducting electric apparatus
Inventor: TERANISHI TSUNEJI
IPC: H01F6/04
Filed: 1987-07-20
Abstract: PURPOSE:To prevent bubbles from being generated during an operating state and when a conductor generates the heat by a method wherein a container is constituted to be double-walled and a superconductor is cooled by a liquefied gas which has been filled into an inner container and whose boiling point is specific. CONSTITUTION:During a usual operation a temperature of a transformer inside a tank 4 is kept near a boiling point of a liquefied gas 8 which has been filled between the tank 4 and a tank 5. Because a boiling point of a liquefied gas 7 inside the tank 4 is higher than a boiling point of the liquefied gas 8 and a temperature of a conductor as a heat-generating part is lower than this, the liquefied gas 7 is not boiled and no bubble is generated. If a short-circuit current exceeding a critical temperature of a superconductor flows through a winding and a conductor has a transition to a normal conduction, the Joule heat is generated; a fault current is stopped after several cycles; if a temperature rise of the winding is kept within the boiling points of the liquefied gas 7 and the liquefied gas 8, no air bubble is generated from a part where the liquefied gas 7 comes into contact with the conductor of the winding even when a system is broken down due to a short-circuit.

Abstract: PURPOSE:To provide the color separating prism device which is small in size and light in weight and has decreased ghost flares while assuring a sufficient optical path length adjusting range with 2- or 3-CCD cameras. CONSTITUTION:The position of a third prism 23 is changed in a range of 23b shown by an alternate long and short dash line from 23a shown by a broken line by an optical path length adjustment and the sufficient optical path length adjustment quantity is assured by a notch 29 disposed on a first prism 21 without increasing the prism length as the notch 29 is a relief for the adjusting range of the third prism 23. The incidence of stray light exclusive of the effective rays to a solid-stage image pickup element 24 is prevented by positioning the front end part of the notch 29 near an effective ray range 30b. The excellent optical color separating prism device capable of exhibiting an effect in decreasing the ghost flares is realized.

The coefficient parameter is operated alternately at each sample period by the distributed signal. Through the processing method like this, the multiplication circuit required at each sampling time of the adaptive digital filter is decreased to nearly a half.
