Title: Radio selective calling receiver
Inventor: ASAI TAKAYUKI
IPC: H04W52/02
Filed: 1992-08-31
Abstract: PURPOSE:To extend the battery service life by optimizing an intermittent reception operating timing so as to reduce an average current consumption in the receiver implementing intermittent reception operation. CONSTITUTION:A reception operation rising time measurement section 105 measures an operation rising time of a radio section 102 at the start of reception.

Abstract: PURPOSE:To absorb the thermal stresses between a furnace wall panel on the high temperature side and a furnace wall panel on the low temperature side and prevent the generation of cracks, etc. by connecting a casing plate which is provided heat pipes at the adjoining section of both panels to a fin by means of a tapered bend plate. CONSTITUTION:A fin 3 between a furnace wall panel 1 on the high temperature side and a furnace wall panel 2 on the low temperature side which are mutually adjacent to each other is cut in the longitudinal direction of a furnace wall tube 7. At the adjoining section of both panels 1 and 2 a casing plate 9 is installed which is provided so as to project heat pipes 8 stepwise to the low temperature side with the heat pipes running perpendicularly to the furnace wall tubes 7. This casing plate 9 and both ends of the cut-off fin 3 are airtightly connected by a tapered bend plate 10 to constitute a thermal stress mitigating derive 11. Since the heat of the furnace wall panel 1 on the high temperature side is conducted to the furnace wall panel 2 on the low temperature side without generating a temperature difference by heat pipes 8, thermal stresses are alleviated.

Title: Electric lock control device
Inventor: FUJIMURA YASUO
IPC: E05B47/00
Filed: 1994-09-28
Abstract: PURPOSE: To make fitting work efficient in a construction site by installing a device for performing signal recognition and lock type judgment, at an electric lock controller, and judging whether an electric lock is a pulse control type lock or a level control type lock on the basis of a signal from the electric lock. CONSTITUTION: A present door state, that is, a door open unlocked state or a door closed locked state, is recognized by a signal recognizing device 17. In the door closed locked state, for instance, an automatic lock type judging start switch 19 is pushed down to apply negative potential between two lines for the fixed time (several seconds) by a control device 16 so as to recognize a change into the unlocked state from the locked state in the meantime. In the case of stopping voltage application to an electric lock 11 from the control device 16 to cause a change into the locked state from the unlocked state, this electric lock is judged to be a level type electric lock.  Positive potential is further applied in the locking direction and stopped, and in the case of the state being changed by the stop of applied voltage, the electric lock is judged to be a level control type, and in the case of the state being unchanged, the electric lock is judged to be a pulse control type. The electric lock can thereby be discriminated even without the knowledge of electric locks.

Abstract: PURPOSE:To confirm the contents of a broadcast and to return an 'understand' signal to a transmitting side by providing a switch to disconnect a direct current loop. CONSTITUTION:Positive polarity is impressed to a normal line L1 and negative polarity is impressed to L2. When a switch 5 is operated during speaking on a telephone set 6, the lines L1 and L2 are switched to a loud broadcasting circuit 11 side, simultaneously the direct current loop is held by a letter transformer 7, and a function can be shifted to the loud broadcast without disconnecting the lines L1 and L2. Next, when the polarity of the lines L1 and L2 are inverted, the direct loop is formed on the channels of the letter transformer 7, a relay 8 and a diode 9, the relay 8 is operated, and the lines L1 and L2 are switched to the loud broadcasting circuit 11 side. At such a time, since the direct current loop is disconnected, it can be used to return the 'understand' signal of the broadcast contents. Thus, the 'understand' signal can be returned to the transmitting side.

Moreover, a filter-forming material 7 is separated from the substrate 1 by dissolving the substrate 1 into an acidic soln., for example. A microfilter having <=0.1mu pore diameter and having <=20% variance of diameters is obtained in this way.
