Title: Work transfer mechanism
Inventor: TANIGUCHI YUUZOU
IPC: B65G43/02
Filed: 1980-01-25
Abstract: PURPOSE: To make a device in the next step to perform sure operation when works contained in guides side by side are transferred by pushing action of a transfer pawl, by providing an overload detecting mechanism in the transfer pawl and detecting that there is no work to be fed.  
     CONSTITUTION: A work 1 contained in a magazine 3 is transferred by pushing action of a transfer pawl 5 and fed one by one into an inspection device in the next step. The transfer pawl 5 makes a reciprocating motion given by a moving block 6 that makes a reciprocating motion along guide bars 7 by a driving wire 17. Though the driving wire 17 and detecting wire 19 are mounted to coaxial sprockets, a shaft 12 stops in rotary motion and a shaft 11 still continues rotation when a work is blocked and stopped in a groove, then the loosened wire 19 is detected by a detecting rollr 20 as an abnormal state, thus occurrence of trouble can be early detected to carry out correct control of the feed operation.

Filed: 1988-01-19
Abstract: PURPOSE:To inhibit the overshoot or undershoot of speed by adjusting the phase of command pulses so that a phase deviation reaches a final phase deviation when the differential value of the phase deviation is brought to zero. CONSTITUTION:A phase comparator 2 supplies a power amplifier 5 with a phase deviation between command pulses (a) and feedback pulses (b) through a low-pass filter 3 and a loop filter 4. On the other hand, a phase deviation (c) passing through the low-pass filter 3 is differentiated by a differentiator 8. A phase-shifting circuit 9 advances or delays the command pulses (a) so that the phase deviation (c) reaches a final phase deviation when an output from the differentiator 8 is brought to zero. Accordingly, the overshoot or undershoot of speed can be inhibited.

Title: Liquid level detecting method
Inventor: SUZUKI HARUHIDE
IPC: G01F23/00
Filed: 1986-01-17
Abstract: PURPOSE:To detect the liquid level in a sealed container without moving a probe by using a variable probe as a transmitting probe and an array probe as a receiving probe and using the both in combination. CONSTITUTION:An ultrasonic wave transmitted by a probe 21a is reflected by an acoustic wave reflecting surface 11b and its reflected wave is received by the array probe 21b. At this time, the level and reception position of the received acoustic wave change with the transmission angle theta of the probe 21a. Namely, when the reflecting surface 11b contacts air 15, the 1st reflected wave of the ultrasonic wave is reflected totally, so the output of the probe 21b increases in peak output as shown by C. On the other hand, the 1st reflected wave is reflected by the reflecting surface contacting liquid 16 at a varied angle theta, there is an ultrasonic wave transmitted in the liquid, so that output of the probe 21b has a small output peak as shown by D and shifts in peak position. For the purpose, the angle theta of the probe 21b is varied stepwise, bit by bit, to find an angle where a large peak shown by C is not obtained and the position of the liquid level 14 can be detected from the angle.

Filed: 1994-01-27
Abstract: PURPOSE:To obtain a video reproducing device in which a video image is not interrupted even when a storage device is replaced with other while the video image is being reproduced. CONSTITUTION:Plural drive units 10, 12 of this video reproducing device read video data from a CDROM 11 storing a video image and transfer the data to a video data expansion circuit 18. However, when a drive unit is switched while the video data are transferred to the video data expansion circuit 18 and any of the plural drive units 10, 12 is being selected with each other, before a CPU 2 finishes the transfer of the video data from the CDROM 11 read at present, the CPU 2 allows succeeding drive units 10, 12 to prepare the read/ transfer of the video data. Thus, even when the drive units are changed over during reproduction of the video image, the video image is not interrupted and the video image reproduction most suitable for a background video BGV or the like is realized.

Filed: 1992-01-21
Abstract: PURPOSE:To obtain an optimum focus even on a cathode-ray tube having a high curvature by using a multiplier to set the horizontal parabolic focus voltage amplitude in the central part and the peripheral part of a picture to an arbitrary value. CONSTITUTION:The horizontal parabolic focus voltage is multiplied by vertical parabolic focus voltage in a multiplier 5 to set the horizontal parabolic focus voltage to an arbitrary amplitude in the peripheral part. The horizonal parabolic voltage has DC cut by a coupling capacitor 2 and is converted into a current by a resistance 4 and is inputted to the multiplier 5. At this time, the resistance value of the resistance 4 is varied to adjust the horizontal amplitude. The vertical parabolic focus voltage which controls the horizontal parabolic focus voltage has DC cut by a coupling capacitor 1 and is converted into a current by a resistance 3 having the variable resistance value to adjust the horizontal amplitude in the peripheral part. Thus, the voltage resulting from addition in an adder 9 of the output voltage of the multiplier 5 and the vertical parabolic focus voltage is used as a synthesized parabolic focus voltage.

Filed: 1986-01-17
Abstract: PURPOSE:To prevent the aluminum wirings of a resin-sealed semiconductor integrated circuit device from being disconnected by selectively forming insulating films on both sides of aluminum wirings, and protecting them against lateral stress.

Title: Bore-hole type axial direction strain gage
Inventor: SAKATA MASAHARU
IPC: G01L5/00
Filed: 1989-01-19
Abstract: PURPOSE:To measure strain in the axial direction highly accurately by bonding a linking post having high rigidity to the bottom plate of an expansion detecting part, and amplifying and transmitting the relative displacement between the upper end of the linking post and an intermediate plate to a signal transducer part through the intermediate plate. CONSTITUTION:A strain gage 1 is divided into two parts, i.e. an upper signal transducer part 7 and a lower expansion detecting part 6 with an intermediate plate 4. A linking post 8 having high regidity is bonded to a bottom plate 3 of the detecting part 6. When strain is changed in a rock bed wherein the strain gage 1 is embedded, the change in interval between the intermediate plate 4 and the bottom plate 3 is transmitted as the expansion and contraction of a large bellows 9 through the linking post 8. Silicone oil in the inside is inputted into or outputted from a small bellows 11 through a path 10 by the expansion and contraction of the bellows 9. The displacement of the bellows 11 is transduced into voltage change through a differential transformer 12. The signal is transmitted to an apparatus on the ground through a signal cable 17. The distance change  l between the intermediate plate 4 and the bottom plate 3 obtained in this way is divided by the distance l. The result becomes approximately equal to the strain change in the up and down directions.
