Title: Method for inspecting volume of plastic bottle and bottle inspecting device for executing method thereof
Inventor: KURUTO MARINIKUSU
IPC: G01B11/02
Filed: 1993-07-06
Abstract: PURPOSE: To precisely measure the volumes of bottles by measuring the height of at least one bottle. CONSTITUTION: The height and the volume of, for example, polyethylene terephthalate(PET)-bottles in a prescribed shape have an extremely strict correlation and consequently, the volume of a bottle 1 can be estimated at good precision from the height of the bottle. A transmitter 4 sends out band like laser beam 5 and a receiver 6 receives the beam. In this case, the upper end 3 of the bottle 1 shuts the band-like laser beam 5 from the lower side of the laser beam 5. The higher the bottle 1 is, the more the bottle 1 enters deeply in the laser band and the more the light quantity to be received is lessened. In the case the height of the bottle 1 is short, the bottle 1 does not so much enter in the laser band and the light quantity to be received is increased. In this way, the height of bottles can be highly precisely measured.

IPC: B41J2/35
Filed: 1987-07-03
Abstract: PURPOSE:To enable electrolytic corrosion not to be generated to a thermal head, by supplying supply voltage to the thermal head only when a printing signal is outputted. CONSTITUTION:A printing signal from a printer circuit 5 is given a thermal head 3 via a signal wire 4. When this printing signal is outputted, the printer circuit 5 gives a control signal prior to the printing signal a photocouplor 7. A light emitting diode 7a of the photocouplor 7 emits light and makes a light receiving transistor 7b to be operated. A power source 8 is brought into an operation state thereby, and electric power is supplied to the thermal head 3. When output of the printing signal is ended, the printer circuit 5 stops output of the control signal. Therefore, electric power supply to the thermal head 3 by the power source 8 is stopped. Then, when printing is performed again, the control signal is outputted from the printer circuit 5, and electric power is supplied to the thermal head 3 from the power source 8.

Title: Device for correcting time
Inventor: KANEKO TETSUYA
IPC: G04R20/00
Filed: 1991-06-13
Abstract: PURPOSE:To provide a time correcting device capable of correcting the time of a clock according to radio time signals. CONSTITUTION:A 440 Hz detecting portion 3 detects from radio signals a signal of 440Hz which announces a time signal. After counting three signals detected by the 440Hz detecting portion 3 a counter 5 opens a correction signal output portion 6 comprising AND gates. A 880Hz detecting portion 4 detects a signal of 88OHz which announces a time signal following the three 440Hz signals. This signal detected is allowed to pass through an open AND gate and input as a first correction signal (a) to a correction time counter 8 so as to actuate the counter 8 with a delay of  t an hour. The correction time counter 8 counts (60- t1) minutes and outputs a second correction signal (b) to the correction terminal of a clock circuit 7a. The clock circuit 7a initializes the number of seconds when the second correction signal (b) is input to the correction terminal of the clock circuit 7a. As a result, the clock 7 has its time corrected after a delay of one minute from the time signal.
