IPC: B21B39/14
Filed: 1981-07-17
Abstract: PURPOSE:To reliably position a guide roll, by accurately detecting a width of a coil material by bringing an electric contact into direct contact with a coil material conveyed. CONSTITUTION:A coil material 13 is inserted by widening a distance between bases 1, 1 and with a drive motor 11 rum, the bases 1, 1 are caused to advance toward the coil material 13. If electric contacts 5a, 5b, 5c, and 5d, protruding toward the coil material (13) side more than guide rolls 2, make contact with the side of the coil material 13, an electric path is formed through the medium of the coil material 13, and an output relay actuated. When the power source of the motor 11 is disconnected, an electric signal, simultaneously, is sent to electromagnetic valves 6, 6 for switching, compressed air is fed and bled to and from a body earth cylinder 3 to move backward the electric contacts 5, the motor 11 slightly runs through the force of inertia and stops running, and the guide rolls 2 are located in a position most suitable for guidance of both sides of the coil material 13.

Title: Pickup for optical disk
Inventor: TONO YASUSHI
IPC: G02B7/09
Filed: 1986-05-16
Abstract: PURPOSE:To drive a pickup by a simple driving system and to obtain fast response by varying a voltage applied between electrodes provided above and below an optical waveguide according to a focus error signal. CONSTITUTION:Laser light which is emitted by a laser diode 4 and passes through a waveguide layer 92 is converged by a diffraction grating 5 for convergence on the recording surface of an optical disk OD and its reflected is split into two by a waveguide type beam splitter 6 and incident on photodiodes 71-74. It is found that variation in focal length is proportional to the intensity of an electric field from the image formation relation of the diffraction grating 5 for convergence, variation in refractive index when a reverse bias is applied between the electrodes 10 and 11 provided above and below the waveguide layer 9, and variation in refractive index required to set the focus of the diffracting rating 5 for convergence on the recording surface of the optical disk OD. Consequently, a focus error signal is detected and fed back to between the electrodes 10 and 11 through a servoamplifier 12. Consequently, the focal length of the diffraction grating 5 for convergence can be varied so as to put the focus on the surface of the optical disk OD all the time and the pickup itself is provided with a focus servo function.

Title: Form separating device

IPC: G03G15/00
Filed: 1983-06-23
Abstract: PURPOSE:To prevent sufficiently a photosensitive body from deterioration and separate a form securely by providing a form thickness detecting means and allowing a separating pawl to contact a charge holding member only when form the thickness larger than specific thickness is detected. CONSTITUTION:A form thickness detection signal circuit 32 performs an operation to a detection signal from a form thickness detecting means 31 by amplification, etc., to generate such a signal as to suit to a succeeding step circuit. A peeling pawl control signal circuit 33 compares the signal from the form thickness detection signal circuit 32 with a reference value and sends out a control signal for bringing the peeling pawl 18 into contact with a photosensitive drum 1 only when the detected form thickness is smaller than the specific value. Namely, when it is judged that the peeling force is not sufficient because the form thickness is smaller than the reference value, the peeling pawl 18 is set at an operation position to separate a form securely, and when it is judged that the peeling force is sufficient because the form thickness is larger than the reference value, the peeling pawl 18 is held peeleds from the photosensitive drum 1 and prevented from damaging the photosensitive durm 1.

Title: Alarm device for replacing looper thread bobbin in sewing machine
Inventor: ISASHI HIROYUKI
IPC: D05B59/00
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To provide an alarm device for replacing a looper thread bobbin for enabling an operator securely to replace the looper thread bobbin by informing the operator of a need for a looper thread bobbin replacement when a product to be sewn is finished with sewing. SOLUTION: A pulse of stitch action signal 15 is issued at every stitch action from a sewing machine 1 to a stitch number subtraction circuit 12a where the number of stitches is decreased by one. When the number of stitches in the stitch number subtraction circuit 12a reaches zero or lower after repeated stitch actions, a signal 17 is sent to a buzzer actuation circuit 13. When a product is finished with sewing, a holder is shifted to an upper position to replace the product, a holder up signal 16 is issued to the buzzer actuation circuit 13. Here, if the signal 17 has been issued to the buzzer actuation circuit 13, the circuit 13 receiving both signals 16, 17 causes a buzzer 14 to sound, and a needlework operator is informed of a looper thread replacement timing.

Title: Display/image pickup device
Inventor: KURIKI MASATO
IPC: H04N5/30
Filed: 1992-04-06
Abstract: PURPOSE:To prevent the deterioration of picture due to reflections from a display screen or the like by using a lot of fine total reflection mirrors and constituting translucent mirrors with gaps with each other. CONSTITUTION:Fine total reflection mirrors 5 of which an inclination angle is theta are used instead of a minute translucent mirrors. In this case, since gaps W are set between the fine total reflection mirrors 5 neighboring to each other, light is transmitted from these gaps W, a function as translucent mirrors 3 is achieved so that the transmissivity of the translucent mirrors 3 is fixed by these gaps W. Also, at the cross-sections of the translucent mirrors 3, an user M watches the picture displayed at a display device 1 through the region of a sidewall 4, so that the transmissivity of the translucent mirrors 3 is decided by the area of the region of the sidewall 4, that is, the inclination theta of the sidewall 4. Since the transmission of the light from the minute total reflection mirrors 5 does not exist also in this case, the display screen of the display device 1 does not reflect on an image pickup device 2.

Filed: 1989-05-02
Abstract: PURPOSE:To make it possible to detect the movement of the sun highly accurate ly by providing a concave lens at the upper part of optical sensors, and aligning the central axis of the concave lens at the symmetrical point. CONSTITUTION:A double-concave lens 4 is arranged at the upper part of optical sensors TW and TE in an oblique-ray box 1. The central axis of the double- concave lens 4 is aligned with a straight line K. In the actual application, optical sensors TS and TN are also provided.

Namely, when the incident angle is smaller than theta1, the sunlight SL' cannot be defected in the conventional method. In this method, even if the incident angle becomes theta2 that is smaller than theta1, the sunlight SL can be detected. Thus, the movement of the sunlight can be detected highly accurately.
