Title: Phase locked loop device
Inventor: SAKASHITA SEIJI
IPC: H03L7/093
Filed: 1987-08-25
Abstract: PURPOSE:To prevent the change of an alternating current signal even when a voltage is changed by adjusting the central frequency of a voltage controlled type oscillator without changing the loop gain of a phase period device and making the sensitivity lower than the conventional one. CONSTITUTION:A signal from a terminal 1 is compared by a phase comparator 2 with an oscillating signal from a voltage controlled type oscillator 5 and a difference signal is generated. Only the component necessary to a phase synchronization out of them if loop-filtered 3 and supplied to the base of a transistor Tr11. Differential amplifying is executed by Tr11, 12 and 16, inputting is executed from the collector of the Tr12 to the base of a Tr19 and a demodulating signal is removed through a Tr30 to execute the emitter follower from a terminal 7. From the collector of the Tr19, a signal is inputted through a Tr28 to the voltage controlled type oscillator 5. A signal to control the oscillating frequency of the voltage controlled oscillator 5 is inputted from a tarminal 6 through a Tr25. Thus, even when the central voltage is changed, the change of the alternating current signal is prevented.

Abstract: PURPOSE:To reduce a heat loss and simplify a piping work by undertaking both heat recovery from the exhaust gas of a fuel cell for use as a heat source for an absorption refrigerator, and condensed water collection for supplying to cell cooling water, using a single direct contact type heat exchanger. CONSTITUTION:Exhaust gas from a fuel cell 1 is introduced to a heat exchanger 3 and rises to enter a heat exchange section 12.

Heat recovery water accumulated in a heat recovery water storage section 14 is used as a heat source for the absorption refrigerator 16. Then, low temperature exhaust gas after heat exchange with the heat recovery water, further rises through the heat exchanger 3 and enters a heat exchange section 4. On the other hand, cooling water flowing from a cooling tower 9 recovers heat in direct contact with the low temperature exhaust gas at the heat exchange section 4 in the form of a counterflow via a cooling and sprinkling means 5. Then, cooling water accumulated in the section 7, together with exhaust gas condensed water, is supplied to a distilled water tank 19 via a distilled water feed pipe 20.

Filed: 1982-12-02
Abstract: PURPOSE:To improve control accuracy of the smoke, by providing a means for heating a transparent window for emitting or receiving light or a light reflecting plate so as to heat the transparent window or a reflective plate. CONSTITUTION:Laser light from a light emitting element 51 of a detecting part 34 is transmitted to a light projecting part 36 through an optical fiber 38 and emitted into an exhaust passage 23a from a transparent window 43.

The light receiving element 53 outputs voltage in accordance with the received amount of light, and the voltage is amplified by an amplifier 55 and output as a smoke detection sigal SA. The smoke detection signal SA changes in accordance with the amount of smoke in exhaust to detect the concentration of smoke. A smoke detector 33 contains heaters 42, 47 to be built inside the light emitting and receiving transparent window 43, 48 facing the exhaust passage 23a, and the transparent windows 43, 48 can be heated. In case of a carbon particle adhering to a side surface of the exhaust passage 23a, if the heaters 42, 47 are electrified, the carbon particle, being immediately sublimated because of high temperature of the transparent windows 43, 48, enables the concentration of smoke to be accurately detected.

Title: Charging method for sealed lead-acid battery and charger
Inventor: YAMAGUCHI KOJI
IPC: H02J7/02
Filed: 1988-08-25
Abstract: PURPOSE:To surely perform trickle charge within an optimum time by detecting surrounding temperature of a storage battery and changing the time applying reserve voltage so as to be inversely proportional to the change of the surrounding temperature. CONSTITUTION:Switches SW1, SW2 are switched to contacts b side by a signal S5 from a voltage polarity switching circuit 7, and voltage of reverse polarity is applied to a storage battery B. A temperature corresponding timer circuit 6 stops a signal S4 after one hour from closing a switch SW, and signals S5, S6 from the circuit 7 are stopped, and switches are switched to contacts a side to finish reverse charge. Charging voltage of normal polarity is applied to the storage battery B for charging. When charging voltage reaches final charging voltage, a final charging voltage detector 4 outputs a signal S2, and a current value switching control circuit 3 outputs a signal S1 to a current value switching circuit 2. Charging current is switched to very small charging current and trickle charge starts. If surrounding temperature of the battery is low, satisfied performance recovery can be obtained by lengthening reverse charging time compared with that at high surrounding temperature.

Title: Optical transmission tube
Inventor: ISHIHARADA MINORU
IPC: C08L27/12
Filed: 1995-07-27
Abstract: PURPOSE: To obtain an optical transmission tube using a fluoro-rubber, which is prevented from the deterioration of optical transmission property as much as possible, as a clad material by incorporating a trapping agent for a residual halogen compound in the clad material. CONSTITUTION: The trapping agent for the residual halogen compound is incorporated in a vulcanized fluoro-rubber and/or rubber elastic body in the clad 2 made by forming the inner surface at least in contact with a core 3 out of the vulcanized fluoro-rubber. Since bromine atom is better than iodine atom in the view point of reactivity though iodine atom is more preferable than bromine atom in the view point of coloring, the vulcanized fluoro-rubber made by vulcanizing the fluoro-rubber having intramolecular bromine atom inferior in the view point of coloring is effectively used as the clad of the optical transmission tube by removing a residual bromine compound from the vulcanized fluoro-rubber obtained by vulcanizing the fluoro-rubber having bromine atom in the molecule.  And since the trapping agent captures also decomposed materials of a vulcanizer, a cross-linking agent or various additives in the rubber elastic body, the deterioration of optical transmission property is prevented.

Abstract: PURPOSE:To prevent the generation of noise no broadcast wave nor a subchannel signal  is available, by providing a squelch circuit, which contains a switch circuit that supplies or cuts off each channel signal given from a secondary demodulator the subsequent voice processing circuit, to a TV receiving circuit. CONSTITUTION:The noise contained in a main carrier wave which is supplied from a main demodulator 6 of a TV receiver is applied to the 1st comparator 12 after the shaping of waveform. The comparator 12 delivers L and H levels alternately to trigger a monostable multivibrator 13. The output of the vibrator 13 is applied to one side of a gate circuit 14. At the same time, the AGC voltage is applied to the 2nd comparator 11 from an AGC amplifying circuit 5b and compared with the reference value. The output of the comparator 11 is applied to the other input of the circuit 14. The output of the circuit 14 is applied to the 1st and 2nd switch circuits 15 and 16 respectively. The subchannel signal which is demodulated by a secondary demodulator 10 is supplied  or cut off to the subsequent audio signal processing circuit in response to the output of the circuit 14. Thus the generation of noises can be avoided in case no subchannel signal nor broadcast wave is available.
