Title: Tracking controlling device of video tape recorder
Inventor: HARIHARA SHIYUUGOROU
IPC: H04N5/7826
Filed: 1983-06-01
Abstract: PURPOSE:To reduce considerably the variation of a time until a tracking servo is stabilized by resetting a signal generating circuit by the output signal of a band-pass filter and forcedly making the frequency of the output signal of the signal generating circuit to coincide with the frequency of a pilot signal. CONSTITUTION:When the 4th pilot signal is given to a selecting circuit 14, an output signal having a frequency of f1 out of output signals of a signal generating circuit 13 is given to a mixer 6. Such a condition is regarded as resetting of the signal generating circuit 13. In this way, the frequency of the output signal of the signal generating circuit 13 which is selected by the selecting circuit 14 and given to the mixer 6 becomes f1. On the other hand, a pilot signal which is given to the mixer 6 through a low-pass filter 5 becomes the 1st pilot signal and, eventually, the frequencies of the pilot signal and output signal given to the mixer 6 become coincident with each other. Therefore, the tracking servo when a video tape 1 is set to the reproducing condition from the stopping condition is stabilized, because the frequencies of the pilot signal and output signal become coincident with each other.

Title: Supercooler
Inventor: YAMASHITA KATSUYA
IPC: F24F5/00
Filed: 1990-04-17
Abstract: PURPOSE:To make it possible to reduce its size by installing a heating device which is provided with a curved flow passage and heats this curved section in a subcooler which exchanges heat between water and refrigerant or brine, passing the water through a flow passage, and continuously generates supercooling water with a temperature of 0 deg.C and below. CONSTITUTION:Water 21 is fed into a water supply port 13 of each heat transfer tube. This water 21 exchanges heat with refrigerant 20 by way of the heat transfer tube 12 and gets cooled when flowing through the heat transfer tube 1. The cooled water is turned into supercooled water 22 of 0 deg.C and below and drained from a drain port 14. The supercooled water 22 is accumulated in a heat storage water tank after it is discharged. Therefore, each heat transfer tube 12 act as a flow passage which carries supercooled water 22 obtained from cooling water 21. The supercooled water 22 is stagnated at a curved section when flowing in the heat transfer tube 12. However, the curved section is submerged with an antifreezing solution 17 of 0 deg.C or over, which prevents the subcooling water 22 from being frozen even if its flow is stagnated. More specifically, the anti-freezing solution 17 whose temperature exceeds 0 deg.C and a freezing prevention vessel which houses the solution plays the role of a heating device for the supercooled water 22.

Abstract: PURPOSE:To apply pinching force in a film width direction and to exactly read bar codes without causing a deflection on a film even when a sensor is made to follow such symbols as the bar codes and the symbols are read by bending a film longitudinal axis at an intermediate part in a longitudinal direction. CONSTITUTION:When a negative film F is arranged in a guide groove 14 with a camera opened and it comes to a condition that an arm 18 is turned and the film F can be conveyed, the film F is pinched between driving rollers 34, 36 and 92 and a pressing roller, driven in a direction shown as the arrow A, passes between pinching blocks 56 and 58 and between pinching blocks 44 and 46, and moved in the direction of a printing aperture 24. In this condition, since the longitudinal axis of the film F is bent between the guide groove 14 and a bevel 14A, resistance force against compression force in a width direction is large at a bending part and the deflection in the width direction never occurs on the film F. Therefore, the bar codes are exactly read by a sensor 82 and a picture is protected from being cut on its surface.
