IPC: B42D15/10
Filed: 1983-07-22
Abstract: PURPOSE:To facilitate and speed-up the positioning of an information tape by providing a cassette positioning member which contacts a flank of a cassette for a filter at two points, and also providing tape positioning members which are arranged opposite to a jig body in specific relation with said cassette positioning member and position the information tape. CONSTITUTION:When the information tape is stuck to the cassette 3 for the filter, the cassette 3 is loaded firstly in the space encircled with a cassette positioning member and information tape positioning members 14a and 14b on the jig body 12 against a leaf spring 16.

Title: Picture input device
Inventor: MURANAKA MASAICHI
IPC: H04N1/19
Filed: 1992-05-26
Abstract: PURPOSE:To improve a picture quality by reducing the difference of a light receiving level among each chip of a contact type CCD image sensor, and reducing the uneveness of a light quantity by arranging rod lenses by shifting them by the same value as the deviation value among each chip of the CCD image sensor. CONSTITUTION:At the time of arranging rod lenses 3 in a row, the rod lenses 3 are shifted by the same size DELTAL' as the deviation value DELTAL of each chip of the CCD image sensor, and the shift position corresponds to the length of each chip of the CCD image sensor (L: length of a chip). That is, the rod lenses 3 are shifted only in the DELTAL' at every the same length as the length of each chip. Thus, the difference of the light receiving level among each chip of the CCD image sensor can be reduced, and the uneveness of the light quantity can be reduced. Moreover, an electric correction (shading correction) can be attained only by slightly reducing an output. The assembly of the rod lenses 3 may be rough according to the increase of the number of the rows of the rod lenses 3, and the fine control of the rod lens in three rows is less than those in one row.

Filed: 1979-10-18
Abstract: PURPOSE: To make it possible to electrically compensate for shortage of mechanical accuracy, by executing sampling of the amount which is equivalent to one rotation of the motor, averaging the sampling amount, and correcting the voltage by which the motor is driven.  
     CONSTITUTION: Four detection pulses P1WP4 are received in order per one rotation of the motor from the rotary head of the video tape recorder equipped with one tack coil and four tack magnets. The pulses P1WP4 are input to the sample holding circuits which are cascaded, after they have been converted to trapezoidal waves through the monostable multivibrators 32, 33 and the integral network 34. The sampling is executed whenever the pulses P1WP4 are input, and therefore, for instance, when P1 is input, the voltage obtained by sampling of one rotation is held in the sample holding circuits 35W39, and the voltage corresponding to one rotation can be input to the control amplifier 41 even if the tack interval is shifted.

IPC: F16H57/12
Filed: 1983-07-22
Abstract: PURPOSE:To reduce vibration at the time of high speed rotation by providing two worms for one worm wheel, by installing No.2 flat gear and a ring having a spiral groove on its periphery coaxially to No.2 worm, and thereby preventing vibration likely to be generated by the rotation caused by back-lash. CONSTITUTION:No.1 and No.2 flat gears 12, 13 are rotated by a motor 15 through No.3 flat gear 14 in the opposite direction to the motor rotation, and thereby No.1 and No.2 worms 9, 10 are also rotated. At this time, a ring 16 also rotates in a sealed trough 17, and lubricant contained therein moves by means of the pumping action of a spiral groove provided at the outside surface of the ring 16. This causes generation of pressure difference in a gap formed between said sealed trough 17 and ring 16. Thus vibration at the time of rotation caused by back-lash in a worm reduction gear can be eliminated according to the direction of provided spiral groove.

Title: Temperature detecting circuit
Inventor: NONAKA HIROSHI
IPC: G01K1/02
Filed: 1981-08-28
Abstract: PURPOSE:To enable to perform a simple detection of a centigrade and a Farenheit temperature, by switching a detecting time for temperature detection according to centigrade or Farenheit. CONSTITUTION:In the case of detection of a centigrade temperature, a switch S is brought to an ON state. An output signal phi4 of a second oscillating circuit 12 has a wide change volume against temperature, and if temperature changes, the output signal phi4 changes and a count value of a counter 3 also changes to enable detection of temperature. Then, in the case of detection of a Farenheit temperature, the switch S is brought to an OFF state. Meanwhile, a relation between centigrade and Farenheit is as shown in a formulaI. A time, for which a signal phi2 counts the signal phi4, is 1.8 times as long as a time for which a signal phi1 counts it. Additionally, by means of a correction signal phi3, a signal, corresponding to a constant 32 in the formulaI, is inputted to the counter 3, and this enables the conversion of the centigrade into the Farenheit. This permits the simple detection of a centigrade and a Farenheit temperature without the need for a special computing circuit.
