Patent JP-S52133261-A (JP)
Title: Alarm sound generator
Inventor: YAMAZAKI HIROSHI
IPC: G04C3/14
Filed: 1976-04-30
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.

Filed: 1982-03-29
Abstract: PURPOSE:To reduce the load of a call processing program of a digital exchange by providing a common circuit in the exchange which corresponds to subscriber's lines with a means to detect a specific bit pattern and insert and send a  digital announce signal. CONSTITUTION:When an announce request call is outputted from a subscriber 1, a switching circuit 4 sends a specific bit pattern to a receiving side channel 7 in a common circuit 3 corresponding to subscriber's lines and a pattern detector 16 detects the sent signal. At the sending of said signal to an announce allowable line 18, an insertion circuit switching signal is generated from a detecting output 17 and an announce signal insertion circuit 19 sends an announce signal on an announce signal supplying line 20 to a decoder 10 in a subscriber's circuit 2. Since the means to discriminate the specific pattern in each subscriber is included in the titled system and announcing service is prepared, the load ordinarily applied to the call processing program is reduced.

Title: Solar heat collector
Inventor: KAWAMORI NOBUTAKE
IPC: F24S10/95
Filed: 1979-04-25
Abstract: PURPOSE:To prevent damage to a heat collecting element facilitating the conveyance and construction of the device by attaching a heat pipe to the heat medium tube through a flexible pipe water-tightly so that it can freely be set to or removed from the medium tube. CONSTITUTION:When the heat receiver 9a of the heat pipe 9 located in the vacuum tube 7 is heated by the solar light rays, the inner operating liquid is evaporated. And the evaporated operating liquid is moved in the heat medium tube 1 and the radiating part 9b located in the flexible pipe 4, and is condensed, resulting in the radiation of latent heat. The heat medium in both the heat medium pipe 1 and flexible pipe 4 is heated by the latent heat. At this time, even though the heat medium tube 1 is expanded or contracted in the axial direction by thermal expansion, the heat collecting element 6 is not affected by the expansion and contraction of the heat medium tube 1, that is, the vacuum tube 7 is not broken even by applying a stress to itself through the heat pipe 9 since the expansion or contraction is absorbed by the flexible pipe 4. Moreover, since each heat collecting element 6 is attached to the flexible pipe 4 so that is can freely be set to or removed from the flexible tube, the conveyance and construction of the device can be facilitated.

Abstract: PURPOSE:To simplify the constitution of a device for controlling the rotational drive of recording disks, by loop-controlling the number of revolution of the motor used in the device if the rotational pulse of the motor is issued until the counting value of a positional pulse of a cycle proportional to a position detecting signal reaches a prescribed value. CONSTITUTION:The frequency dividing ratio of a frequency divider 17 is controlled by a position detector 9 which detects the moving quantity of a pickup 3 from a reference position, AD converter 16, etc., and the frequency dividing pulse of a positional pulse of a cycle proportional to a position detecting signal is generated. When a prescribed number of the pulse is counted by counter 21 of a set cycle detecting circuit 19, a decoder 22 outputs the reset signal of the FF24 of a set cycle detecting gate circuit 23 and, if a rotational pulse from a frequency generator 13 united with a disk motor 2 in one body exists before the reset signal is outputted, it is discriminated that the motor 2 reaches its limit speed. Then a switching pulse from the gate circuit 23 is impressed and a closed loop for controlling the motor 2 is formed through a switch 7. Therefore, a simply constituted device for controlling the drive of recordinging disks which does not need any divider, frequency-to-voltage converter, etc., is realized.
