Title: Photographic camera
Inventor: DONARUDO MARUKOOMU HAABEI
IPC: G03C3/00
Filed: 1989-09-12
Abstract: PURPOSE: To discriminate whether a film roll inside a camera is exposed or partially exposed by magnetically encoding and recording information controlling the movement of a film which succeeds when a film leader is placed outside a cassette shell to the film leader. CONSTITUTION: A film belt F is entirely exposed, data for preventing double exposure(DEP) are magnetically written on the film leader nearly just before the film leader 43 is taken up again. When the film belt F is quickly taken up inside the film cassette 1, data for roll interruption(MRI) are magnetically written on the leader 43 instead of the DPE data. When the cassette 1 is loaded inside a loading chamber again, first the film leader 43 is taken out from the film cassette, and which data of the DEP data or the MRI data are encoded is checked. Thus, whether the film roll inside the camera is exposed or partially exposed is discriminated.

Title: Laser oscillator
Inventor: TAKAGI SHINICHIRO
IPC: H01S3/131
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a laser oscillator by which the overshooting of an optical power is avoided and a stable laser output can be obtained. SOLUTION: An oscillator control unit 5 receives a laser output command signal 23 from an NC apparatus 3 and outputs a voltage waveform command signal 25 which is supplied to a power supply unit 9. The power supply unit 9 supplies a discharge power to an oscillation head 15 which outputs a laser beam LB. The outputted laser beam LB is detected by a laser beam detecting means 17 which supplies a detection signal to a comparator 19. On the other hand, a simulator unit 21 simulates the operation since the oscillation control unit 5 receives the laser output command signal 23 till the laser beam detector 17 outputs the detection signal V2 and supplies a simulation signal V1 to the comparator 19.  The comparator 19 detects the deviation between the detection signal V2 of the laser beam detector 17 and the simulation signal V1 and the negative feedback of the deviation is performed by an adder 7 to correct the voltage waveform command signal 25.

Abstract: PURPOSE:To enhance productivity by preforming a spherical recessed part with respect to a first prepared hole to prevent damage of a coining die, and forming a predetermined slit-like recessed part in the peripheral part of a beam passage hole to align hole centers of a first and a second members with each other. CONSTITUTION:Coining is applied sequentially to a prepared hole 2 in a second member 7, to a prepared hole 4 in a recessed part 3 of a depth L and to a hole 5 whose center is aligned with a center of the hole 4. The second member 7 is welded to a first member 6 to constitute a third grid electrode. Since the coining work is used, work pressure can be restrained to a small value, and a thin slit-like recessed part having a depth of 40-60% of material thickness and 0.4mm or more and recessed part volume of 2mm<3> or more can be formed without deformation in the peripheral part of an electron beam passage hole. Since the third electrode is formed of the members 6 and 7, centers of the holes 10, 11 can be precisely aligned with each other. With this constitution, astigmatism correction can be adequately performed and productivity is enhanced.

Title: Particle measuring device
Inventor: FUJITA AKIHIRO
IPC: G01N15/14
Filed: 1989-09-14
Abstract: PURPOSE:To obtain the particle measuring device having a spherical cell window which can easily be worked and has an excellent performance and can be manufactured simply at a low cost by using a specific optical material separately on a fluid side and the outside of a measuring cell as a material of the cell window. CONSTITUTION:Cell windows 22, 23 on a fluid side (the right side in the figure) and the outside of a measuring cell (the left side in the figure) are constituted of different optical materials, and a structure for joining them by the center plane is adopted. As for the cell window 22 having a concave surface 22' coming into contact with a fluid, for instance, a sapphire is used, and as for the window 23 having a convex surface 23' on the outside of the measuring cell, an optical material in which a refractive index n'2 in wavelength of an incident laser light is almost the same as a refractive index n2 of the cell window 22 is used. The corrosion resistance of the fluid side of the cell window 21 can be improved, and by adjusting the refractive indexes of the cell windows 22, 23, a refraction in the boundary of the cell windows 22, 23 can be disregarded. The concave surface 22' and the convex surface 23' can avoid the influence of the refractive index in the case the fluid is changed by allowing the center of curvature of the concave surface 22' to coincide with a condensing point of the laser light. The cell windows 22, 23 are ground and polished separately, and thereafter, both of them are joined.
