Filed: 1986-05-31
Abstract: PURPOSE:To reduce the size and weight of a light emitting device by using a light transmission member having a function for correcting a light from a light source to parallel beam and an ellipse correcting function. CONSTITUTION:The second surface (plane of emission) 3b of a light transmission member 3 is brought in coincidence with the end 5a of an opening side, and a first surface (plane of incidence) 3a is disposed in a housing 5. Electrodes 6 are energized to emit a light beam L1 from a light source 12 toward a light transmission member 3. The beam L1 is refracted at the first surface ea of the member 3, corrected to a parallel beam (light beam L2) to the second surface 3b. lt is elliptically corrected by the second surface 3b to an emitted light beam L3 in which its perpendicular section is circular and its optical axis coincides with the axial direction of the housing 5. The beam L3 is applied as a spot S on a recording film 33 opposed to a guide groove 34, and the reflected light is introduced through the film 33 and a disk substrate 32 to an objective lens 22 side.

Filed: 1986-05-30
Abstract: PURPOSE:To improve an interference resistance characteristic by forming a demodulator to a shape of a double loop, and using two kinds of filters of a correlating filter for interference resistance, and a filter for absorbing a variance of an element for carrier tracking. CONSTITUTION:A PLL 16 of a double loop is used as a reverse spread correlator, a reverse interference is executed by the first loop, and an intermediate frequency signal which has become only a primary modulation is obtained, and inputted to the second loop used for extracting a data, through a correlation use band pass filter 2. An interference resistance characteristic is determined by the first band pass filter 2, and a variance of a circuit element which is realized is absorbed by a loop filter 10 of the second loop. A delay time of the band pass filter 2 of the first loop exerts no influence on the stability of the whole loop, therefore, the interference resistance characteristic can be improved by narrowing a band. Since the interference resistance characteristic is determined by the band pass filter 2 of the first loop, the loop filter 10 of the second loop can be made to have gentle characteristic, and it can be realized easily to lower the element sensitivity of circuit parts to be used.

Title: Power circuit
Inventor: KANEKO SHINJI
IPC: H02M7/217
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent surge currents and reduce power loss in a power circuit which converts alternating currents into direct currents. SOLUTION: A transistor 2a of a photo relay switch 2 is placed between a bridge diode BD1 and a smoothing capacitor C1. The transistor 2a is turned on by the emitted light of the light emitting diode 2a. When a switch SW1 is turned on, a relay control circuit 3 is synchronized with AC input and PWM (Pulse Width Modulation)-controls the on state of the photo relay switch 2, so that its duty ratio is gradually increased from 0%. As a result, currents are gradually passed through the smoothing capacitor C1, and the production of a surge current is prevented. In addition, since the transistor 2a of the photo relay switch 2 is no more than tens of mΩ in on resistance, its power loss is low.

Filed: 1988-05-26
Abstract: PURPOSE:To improve the measurement accuracy by providing relatively a magnet and a Hall element on a movable part and a fixed part, respectively, as an electric signal generating part. CONSTITUTION:As a movable part 1 and a fixed part 2 for receiving external pressure are brought to minute displacement relatively through a flexible part 3, a relative distance between a magnet 4a and a Hall element 4b is also brought to minute displacement. Subsequently, by a variation of the distance between the magnet 4a and the element 4b, a ratio of a line of magnetic force for passing through the element 4b among the lines of magnetic force emitted from the magnet 4a is varied, and Hall electromotive force of the element 4b is varied. Also, by setting so that the displacement at the time of a rated load does not exceed an initial gap between the magnet 4a and the element 4b, the magnet 4a and the element 4b always hold a non-contact state, therefore, initial characteristics of both of them are unchangeable permanently, and deterioration of the characteristic and damage do not occur at all. In such a way, by constituting an electric signal generating part of the magnet 4a and the element 4b, stable electromotive force being free from hysteresis can be obtained extending over a long period of time.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a smile display which can automatically create a smiling state by providing the proper points of a seal of a spectacle shape having a tacky adhesive layer with a pair of arcuate slits. SOLUTION: The seal body 1 is formed by providing the rear surface of a thin film made of a chromatic soft synthetic resin with the tacky adhesive layer and a frame 2 pretending to be a frame is formed by printing the edge portion of the seal body 1 with a color separate from the color of the seal body 1. The arcuate slits 3 which are the portions blanking the proper points of the seal body 1 to an arcuate shape are formed. At the time of use, a user sticks the arcuate slits 3 to the surface of the spectacles. The arcuate slits 3 are then easily recognizable as the eyes and a spectacle wearing person looks as if the person is laughing, arousing the interest of other persons. If such spectacles are worn, the user's eyeball portions are concealed but the user is able to view forward through the arcuate slits. The addition of the slit portions profiling the eyelashes is equally well.  In such a case, the forward recognition is easier.

Abstract: PURPOSE:To suppress the deterioration of the production control accuracy by deciding the operation carried out by a start/end transmission means as a misoperation when the work time is less than the minimum reference time. CONSTITUTION:When an operator operates an end switch 21b after the end of a prescribed work process, a control routine is controlled to decide whether a timer is started or not.
