Title: Dynamic balancing device in press machine
Inventor: TOMITA SHOJI
IPC: B30B15/06
Filed: 1984-07-26
Abstract: PURPOSE:To provide a titled device which reduces the size of a counter weight (CW) and reduces the space for attaching said weight by attaching the CW via a link to said device and making large the length of said link and kinetic energy. CONSTITUTION:A crank shaft 1 of a crank type press machine provides linear forward and backward motion to the link 4 via a connecting rod 3 attached eccentrically thereto when the crank shaft rotates. Then the link 4 turns around a pivot 6 and moves back and forth the CW7 along a guide 9 in the vertical direction without rolling. The static and dynamic balance can be therefore obtd. by making large the length of the link and kinetic energy in accordance with the weight requiring balancing. The required balance is thus obtd. with the small-sized CW and eventually the smaller space for attaching the CW is required.

Title: Section control circuit for sorter
Inventor: YAMAUCHI YASUSHI
IPC: B65H39/11
Filed: 1986-07-02
Abstract: PURPOSE:To execute efficiently a software processing by comparing sorter section information with the information outputted from the priority sequence memory part of the section box of a sorter and discriminating a present priority code. CONSTITUTION:A selector 4 selects and outputs the sorter section information of registers 31',32'.35 by a selecting signal from the internal command register. AND gates 60-610 obtain the AND of the output of a memory 5 and the output of the selector 4. A buffer 7 inputs the output of the memory 5 and respective outputs of the AND gates 60-610, and adds a minus code to the data of the memory 5 coincident to the output of the selector 4. A CPU sets the address corresponding to the value to store the priority sequence of a present time point to a counter 11, and inputted until a minus code comes to disappear. Thus, the processing of the software can be efficiently executed.

Title: Strengthening of weathered rock bed
Inventor: MURAYAMA SAKUROU
IPC: E02D3/115
Filed: 1980-11-07
Abstract: PURPOSE: To form a uniformly frozen rock having a high strength and a high deforming resistance by filling a weathered rock with water prior to the freezing of the rock.  
     CONSTITUTION: A cut-off wall 1 is provided to a weathered rock G. Water is spread through a water injection pipe 3 buried in the rock G in such a way as to give sufficient moisture to a region A to be strengthened of the rock G and also to fill the cracked portion of the rock with water. In this case, the water- holding power of the rock and the regulation of the flow rate of water can be easily attained when water mixed with a thickening agent, e.g., CMC, etc., is used. When a refrigerant is started to flow through a freezing pipe 2 and the amount of water to be spread from the water injection pipe 3 is reduced, the rock in the region A is started to be frozen from its cracked portion around the freezing pipe 2 and the passage of water, filled with water, is frozen and blocked, whereby the frozen water plays a role of an adhesive in the region A to form a frozen rock F having a high strength, a high deforming resistance, and a high homogeneity.

The light guides 4 and 21 transmits the light with high efficiency since a part  of the circular section of a ring in parallel to the surface forming the ring is scraped off to obtain a plane 40 which is then polished. In such way, a rotary transformer of a rotary magnetic head having excellent characteristics is obtained with a simple assembly.

Title: Power converter and uninterruptible power supply
Inventor: YAMATO IKUO
IPC: H02M5/27
Filed: 1992-06-16
Abstract: PURPOSE:To provide a high frequency link system power converter in which distortion of output voltage waveform caused by dead time is suppressed sufficiently. CONSTITUTION:The power converter comprises an inverter 1 and a cycloconverter 3 coupled through a transformer 2, wherein driving signals for the inverter 1 and the cycloconverter 3 are produced based on a carrier signal (ec) generated from a carrier generating means 12 in order to convert DC power from a DC power supply into three-phase AC voltages vuv, vvw, vwu. The power converter further comprises means 15 for delaying PWM signal at least by an amount corresponding with ON delay of the inverter 1 caused by an ON delay means 18. Since dead time of the inverter 1 is prevented from being included within PWM interval of the cycloconverter 3, distortion can be suppressed without requiring dead time compensation of the inverter 1.

Filed: 1985-07-18
Abstract: PURPOSE:To make the detection of slant screwing, screw breakdown and 'no screw' performable, by measuring the driving time of a motor screw where a voltage drop by the driving current detected is more than the discriminating reference voltage, and making is detect whether the screw-down is good or not. CONSTITUTION:When a motor driver of an automatic screwing operates and such voltage VR as having a waveform 22 appears in a resistor R, it is compared with output voltage VO of a digital-to-analog converter 17 by a comparator 14, and a pulse 23 is inputted into a counter 15. Here, when it is set down to an input pulse Na=4, the counter 15 counts square pulses as four pieces, outputting to an - input terminal of a collator 16, setting it down to a minimum pulse Nb=2 in advance. On the other hand, a computer 18 outputs Nb=2 while it a timer 19 to a screwing completion expected time To and since, transmitting to this To so that the Na is within the To at the collator 16 and judged as larger than the Nb, and it comes under a criterion 1 whereby screw-down is judged as good, outputting it from the computer 18. If Na=1 is the case, it comes to 0<Na<=Nb so that it is judged as a defective by a criterion 2.

Title: Annealing device for semiconductor
Inventor: MACHI YOSHIO
IPC: H01L21/26
Filed: 1980-11-10
Abstract: PURPOSE:To recover a defect of a semiconductor by heating at a low temperature for a short time by heating the semiconductor at the prescribed temperature and emitting a flash light. CONSTITUTION:An Si semiconductor having a defect is heated to the prescribed temperature of 300-1,200 deg.C in non-oxidative gas atmosphere, and is emitted more than once by flash light of a xenon lamp. Since the Si semiconductor absorbs the flash to heat itself at this time, the defect can be abruptly recovered at a lower temperature than the conventioal temperature.

Title: Method for joining ceramics to metal or ceramics
Inventor: UCHIDA SHIRO
IPC: C04B37/02
Filed: 1991-06-03
Abstract: PURPOSE:To join a ceramic article to a metal or ceramic article in a high joining strength. CONSTITUTION:Joining plates consisting of ductile metal plates each having a chromium thin film layer are placed between a ceramic article and a metal or ceramic article, and heated and pressed each other so that the reaction layer between each chromium layer and each ceramic article has a thickness of 1-3mum. The chromium layers of the joining plates are brought into contact with the ceramic articles to metallize the surfaces of the ceramic articles and simultaneously react the chromium with nitrogen atoms contained in the ceramic articles, thereby forming CrxNy bonds between the chromium thin films and the ceramic articles to join the ceramic articles to each other. When the thickness of the produced layer is 1-3mum, the joining strength of the joining part is most improved.

Title: Nitric acid pickling solution for metal
Inventor: KOTAKE MASAYOSHI
IPC: C23G1/08
Filed: 1980-11-10
Abstract: PURPOSE:To obviate the abrupt generation of gases during replenishing of a concd. nitric acid and provide sufficient effect for suppression of production of gaseous NOx by contg. a proper amt. of hydrogen peroxide to a nitric acid pickling soln. added with a sulfamic acid. CONSTITUTION:Hydrogen peroxide of an amt. to be contained at 0.01-10% in the liquid is contained in a nitric acid pickling soln. of <=0.5wt% residual sulfamic acid concn. This liquid composition obviates the abrupt generation of gases despite replenishing of a concd. nitric acid of >=20% directly to this soln. This soln. shows a blue color as it contains hydrogen peroxide, and when the hydrogen peroxide is consumed on continuation of metallic pickling, the liquid shows a yellow color and therefore the timing for replenishing of the hydrogen peroxide is known. The replenishing of the sulfamic acid for suppressing the production of gaseous NOx is simply required to be carried out at the point of the time when the colored gaseous NOx is easy to be produced, and the need for quantitative analysis of the residual amt. of the sulfamic acid is eliminated.
