Title: Automatic corrector for die height of press
Inventor: ABE TOSHIO
IPC: B30B15/00
Filed: 1983-01-28
Abstract: PURPOSE:To enable forming with high accuracy with a relatively simple construction by detecting electrically the change in a die height and controlling the pressure of a protector hydraulic chamber with the resulting signal. CONSTITUTION:Press forming is performed between a die 3 provided on a bolster 2 and a punch 10 provided on the bottom surface of a slide 8. Oil is supplied from an air driving pump 12 to the inside of the protector hydraulic chamber 8a in a slide 8 and the pump 12 is run as the primary pressure of a pipeline 13 is regulated to a secondary pressure by a pressure regulating valve 14. A valve 14 is controlled by a die height detector 16 provided between the bolster 12 and the slide 8. The detector 16 is, for example, a potentiometer which detects electrically the vertical movement of the slide 8. When the set die height fluctuates on account of a change in the oil temp. or the temp. of the die 3 and the punch 10, the detector detects the fluctuation in the temp. and feeds a signal to the valve 14. Then the valve 14 regulates the secondary pressure to be supplied to the pump 12 according to the die height and therefore the oil pressure to be supplied to the chamber 8a changes thereby correcting the change in the die height.

Title: Speed sensor
Inventor: YOKOTA HIROYUKI
IPC: H01F7/02
Filed: 1994-02-03
Abstract: PURPOSE:To prevent cracks in a sintered material due to the tightening force of a magnet by forming a tightening force absorbing groove at a resin part between the magnet and a rotary shaft. CONSTITUTION:A resin part 24a between a magnet 23 of a resin part 24 and a rotary shaft 5 is provided with a plane-view circular tightening force absorbing groove 25. When a tightening part 5a on the top of the shaft 5 is tightened by means of punch, its tightening force is subjected to the resin part 24a on an internal circumferential surface 23a side of the magnet 23, and an external wall 24d of the resin part 24a is deformed toward the magnet 23 side by means of its compression stress; however, the deformation of the resin part 24a is certainly absorbed by means of the absorbing groove 25, and the magnet 23 is not subjected to the influence of the tightening force. Consequently, the cracking of the magnet 23 in the strong magnetic field made by the sintered material due to the deformation of the resin part 24a can be prevented.

Abstract: PROBLEM TO BE SOLVED: To realize a manufacturing method of a fitting type connection terminal capable of easily manufacturing a fitting type connection terminal with low insertion force, good crimping performance or solderability at low cost. SOLUTION: Both sides of a strip material are tin plated in different thickness, and a die material 5 is punched out from the strip. A tab 12, which is a fitting part, is bent in the direction indicated by an arrow A1, a wire barrel 11 which is a crimping part with electric wire is bent in the direction indicated by an arrow A2. Therefore, the tub 12 and the wire barrel 11 are bent inversely, the tub 12 is bent in a way that the thin tinning layer comes out side, and the wire barrel 11 bent in a way that the thick tinning layer comes out side. On the surface of the tub 12 a thin tinning layer is formed, and insertion force is reduced. On the surface of the wire barrel a thick tinning layer is formed and the crimping performance is improved.

Title: Detector for weld line
Inventor: ITOU TAKASHI
IPC: B23K9/127
Filed: 1983-01-26
Abstract: PURPOSE:To perform automatically a welding operation with high quality by providing a detector with a spot light source means which irradiates successively the light from three spot light sources to the surface near the weld line of materials to be welded and a detector for the position of two-dimensional light spot which receives the light reflected from the spot light source means, etc. CONSTITUTION:A spot light source means 3a of a detector includes three spot light sources 16, 17, 18 realized by light emitting diodes, etc. The light sources 16, 17, 18 are lighted successively by each piece and are so arranged that when one light source, for example, 16 is lighted, the remaining sources 17, 18 are put out. When one light source, for example, 16 is lighted, the beam light 16a thereof is reflected irregularly by the surface of materials 6 to be welded near the weld line 7 and the reflected light arrives at the photodetecting surface of a detector 13 for the position of two-dimensional light spot via a condenser lens 14. The position of the weld line is thus detected with high accuracy and the welding operation is accomplished automatically with high quality.

Title: Acoustic signal control system
Inventor: KODAIRA MITSUHARU
IPC: G10K15/04
Filed: 1993-01-27
Abstract: PURPOSE:To prevent the occurrence of an abnormal sound caused by a signal with a frequency component different from a prescribed frequency by synchronizing the switch timing between the generation time of a first sound and the generation time of a second sound succeeding to that with the phase change point of the frequency signal of the pitch of the sound to be outputted within the generation time of the first sound. CONSTITUTION:A note length signal outputted from a note length generation circuit 305, that is, an address increment clock 320 is synchronized with a preset signal from a sound generation circuit 309 in a delay flip-flop 101, and is shifted to the end timing of the preset signal. Thus, no sound generation circuit is set by the data in the transient state of the address change in a ROM since the timing when the address n of a melody sequence ROM 308 is changed to an n+1 address becomes after the preset signal is ended, and no frequency component different from the prescribed frequency appears in the output signal of the sound generation circuit, and no abnormal sound occurs.

Title: Optical comb type filter
Inventor: MURAI TSUNEO
IPC: H04N9/07
Filed: 1979-02-05
Abstract: PURPOSE: To achieve better characteristics and lower cost by constituting the optical comb-type filter by which the signal components of at least the basic space frequency are removed with respect to the incident light of linearly polarized light in the sate of less number of using 1/4 wavelength plates.  
     CONSTITUTION: The optical comb-type filter PC is constituted by a comb-type filter element PC2 composed of a crystal plate which attenuates the signal components twice higher than the basic space frequency, a λ/4 plate 2 and a comb-type filter element PC1 composed of a crystal plate which attenuates the signal components of the basic space frequency. When the incident light is linearly polarized light, the incident light passes straightly through the filter element PC2, is circularly polarized with the λ/4 plate 2, is removed of the signal components of the basic space frequency in the filter element PC1 and is sent to an image pickup tube. Here, the signal components of the frequencies twice higher than the basic space frequency exist but they are smaller than the energy of the signal components of the basic space frequency and therefore the hindrance that they give on the reproduced images is light. Hence, the filter of low cost and good characteristics is obtained.

Abstract: PURPOSE: To obtain a silicon based oxide having low dielectric constant and reflow type mesh structure by introducing a specified compound having Si-H radical and H2 O2 into a reaction chamber containing a semiconductor substrate, causing mutual reaction under specified conditions and subjecting intermediate reaction products to thermal dewatering. CONSTITUTION: After forming a lower layer metallization 12, a semiconductor substrate 10 is set in the chamber of a semiconductor production system. An aromatic or heterocyclic compound having Si-H radical of cyclic or mesh structure is then introduced, along with H2 O2 , into the chamber and caused to react each other in a vacuum of 665Pa or below at a temperature of -10 deg.C to +10 deg.C. Consequently, an intermediate product having high flatness, where reflow is accelerated by the Si-H radical, is produced on the semiconductor substrate 10. It is then heat treated to cause dewatering reaction in the intermediate product thus obtaining a low dielectric constant silicon based oxide 13 having reflow shape and mesh structure.
