Title: One-dimensional wide-field photodetecting lens
Inventor: AGATA TOMIO
IPC: G02B5/08
Filed: 1982-11-08
Abstract: PURPOSE:To obtain a compact lens with a wide visual field and a large diameter by fixing a focal surface on a slanting surface of a prism cemented to the parallel reverse surface of the upper part of an off-axis plano-convex cylindrical lens body. CONSTITUTION:A figure shows the photodetection characteristics of this lens. Namely, when the prism 4 with the slanting surface C is cemented to the top surface of the lens body 3, an optical system is separated at a surface F if deviation in focal surface from a surface C occurs owing to a size error of parts, thereby correcting the deviation easily by the movement of the upper-side prism 4. In a figure, a line detector 5 is shown.

Title: Optical disk recording and reproducing device
Inventor: HAMAGUCHI SHUNEI
IPC: G11B7/09
Filed: 1986-08-20
Abstract: PURPOSE:To obtain an optical disc recording and reproducing device of 'the two-stage coupled servo system' which is stable as the whole with a simple constitution by providing a phase delay circuit in the first servo system which controls the first driving mechanism which drives a converging lens in accordance with a tracking error signal. CONSTITUTION:The tracking error signal is given to the first servo system consisting of a low-pass filter 38, a phase compensating circuit 40, and a means 42 and the second servo system consisting of a phase compensating circuit 44 and means 48 and 18. In the first servo system, the tracking error signal has the phase delayed as prescribed by the phase delay circuit 38. In the second servo system, the tracking error signal passes as it is. Consequently, the phase difference between both servo systems is reduced, and this phase difference is held within 180 deg. up to a relatively high frequency area, and therefore, the gain of the second servo system is increased to perform stable control. Since complicated phase advance compensating circuits are not required for securing >=180 deg. phase difference, the constitution is very simplified.

Abstract: PROBLEM TO BE SOLVED: To enable accurate measurement of distance to the object by equipping a distance measuring device with a means for operating the interval between the object and one's own vehicle, interpolating the pulse count value, based on the propagation delay time and measurement discharge voltage. SOLUTION: The electromagnetic waves emitted from a light sender 6 are reflected from an object, and reflected waves are detected with a light receiver and detector 7. This detection signal stops a counter 8, and makes a discharger 9 start the discharge for interpolating the distance measurement by the counter 8. A distance arithmetic unit 12 interpolates the count value of the counter 8 by the value of a signal level detector 10 obtained by an A/D converter 11, and computes the distance to the object. Next, a correction determiner 13a operates the correction, using the maximum and minimum signal levels obtained by a maximum/minimum signal level detector 15. The compensator 14 performs the corrective operation of the distance of measurement outputted from the device 12, using the correction obtained by the device 13a.

Title: Preheating system for electric equipment
Inventor: KUROBA KATSUAKI
IPC: G06F1/00
Filed: 1985-09-06
Abstract: PURPOSE:To save electric power and to prolong the life of electric equipment by providing a timer which is inserted in series with a temperature sensor contact and closed in a set time, and preheating the equipment only when the contact of this time is made and inhibiting the equipment from operating during the preheating. CONSTITUTION:When a preheating period set by a timer 12 is elapsed, the contact k4 is broken, a relay 8 stops, and a contact k14 is also open, so a command for stopping mechanism part operation is not supplied to a control circuit 3. Consequently, the control circuit 3 puts a mechanism part 2 in initial resetting operation and self-diagnosing operation. An automatic teller machine (ATM) 1 enters a transaction state until an operation time thereafter and when the operation time ends, a power source disconnection switch 6 is closed and a current flows through the relay winding R of a relay 10 to break a contact k3, so that the ATM 1 stops. Then, even when a temperature sensor 7 is closed, the preheating operation is limited by the timer 12, and even when the contact of the sensor 7 is closed before the preheating time, an AC power source is limited by the timer 12.

CONSTITUTION:Stainless wires of 66-100 microns, for instance, can be used for electric heating wires 1 and common terminals 3. Heat-resistant synthetic resin such as Tetron is often used for a cloth 2. In the center part of a quilt A, a common heating and warmth-keeping cloth 2 is provided, while heating and warmth-keeping cloths 31-34 are respectively provided in the vicinities of four sides of a quilt. Since the quilt A itself performs heating and warmth-keeping opeations, a top plate is not provided to a Kotatsu frame 4.

Abstract: PURPOSE:To make precise positioning and mounting of a disc to a processing unit by once mounting/demounting the disc to/from an intermediate holding means on the unit side by a carrier means such as a robot hand and mounting/ demounting the disc to/from a disc fixing means connected to a spindle. CONSTITUTION:First, an intermediate holding means 14 advances from a retreat position shown with a chain line in the direction of an arrow (a) and at the same time a disc D1 is carried to the position of a disc D2 shown with a chain line by a carrier means. Then, the holding mechanism of the intermediate holding means 14 which has advanced as shown with a solid line operates, so that the disc D2 may be held by the intermediate holding means 14. Next, the carrier means retreats, a disc fixing means 7a operates while the disc D2 is held only by the intermediate holding means 14 and so the disc D2 is fixed by the disc fixing means 7a. Thereafter the intermediate holding means 14 stops its operation and retreat, so that the disc D2 is opened. Thus, the disc D2 is held by the disc fixing means 7a and rotated by a spindle 12.

Together with a setting action, a tip of a cassette cover opening/closing protrusion 6 abuts on a cassette opening protrusion. A cover 4 rotates clockwise around a rotational shaft 5 and the opening of the cover 4 is finished before completion of setting. Upon resetting, the cassette in the open state rises together with the cassette holding part 13. When a cassette ejection is carried out in this state, the cassette cover opening/closing protrusion 6 abuts on a closing protrusion 15, and the cover 4 rotates counterclockwise to close, thereby ejecting and taking out the cassette in the closed state.
