Title: Work machine control device of construction machine
Inventor: TOZAWA SHOJI
IPC: G05B11/32
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To enhance a position following ability of a work machine operation cylinder and secure a specified finishing accuracy even when excavation load is increased in horizontal leveling work or slope formation work. SOLUTION: A position following feedback control system comprises an operation lever 33, a controller 21, a control valve 36 and feedback groups 43bm, 43st and 43bk from each of angle sensors 16bm, 16st and 16bk of a front linkage or the like. A signal line 51, which is designed to adjust a feedback gain or a feed forward gain, responding to an excavation load, is provide in this control system. The load pressure of a stick cylinder 14st which works mainly for a slope formation work or the like, is detected with a pressure sensor 22st or the like, thereby adjusting increasingly the feedback gain or the feed forward gain by means of a look up table 52, responding to the increase in this cylinder's load pressure. When the excavation load is larger, the attenuation of the front linkage is also great.  It is, therefore, possible to protect the control system from being unsteady even when the gain is increased.

Title: High voltage generating circuit
Inventor: IMAMURA NOBUAKI
IPC: H04N3/185
Filed: 1989-02-14
Abstract: PURPOSE:To make a high output voltage stable by controlling the period when a switching transistor(TR) is turned on in response to the reduction of the high output voltage. CONSTITUTION:When a high voltage output current IH flows to an anode by the adjustment of brightness increase of a cathode ray tube 15 or the like and a high output voltage EH is dropped, the voltage drop is detected by a voltage detection section 9 of a switching control circuit 59. The switching control circuit 59 gives an ON signal with a pulse length proportional to, e.g. the voltage drop to a switching TR 43 of the switching circuit 23 based on the detected voltage. The switching TR 43 applies ON operation for the ON period of the control signal fed from the switching control circuit 59 and the summing voltage generated from a summing voltage generating coil 21 is fed to the high voltage output EH by the ON period only. Thus, the high voltage is made stable against a change in the high voltage current flowing.

Title: Input buffer circuit
Inventor: TANAKA TOSHIAKI
IPC: H03K19/003
Filed: 1988-02-16
Abstract: PURPOSE:To improve the resistance to radiant ray by connecting a gate of an N-MOST at an output terminal to an output terminal of a voltage detection circuit detecting the fluctuation of a logic threshold voltage so as to bring the N-MOST at the output terminal from the conductive state into the nonconductive state. CONSTITUTION:A threshold voltage of an N-MOSTQN1 is decreased by radiating a radiant ray such as gamma-ray and a logic threshold voltage of an inverter comprising a P-MOSTQP11 and an N-MOSTQN11 is lowered. Thus, an N- MOSTQN3 is nonconductive and an inverter comprising a P-MOSTQP1 and the N-MOSTQN1 is operated. This is equivalent that the gate width of the N-MOST is decreased, the threshold voltage of the N-MOST is not lowered and the logic threshold voltage of the inverter comprising the P-MOSTQP1 and the N-MOSTQN1 is not decreased. Thus, the margin between the rated maximum value of the low level input voltage and the logic threshold voltage of the inverter comprising the P-MOSTQP1 and the N-MOSTQN1 is increased and the resistance to radiant ray is improved.

Title: Device for producing high melting high toughness metal
Inventor: KIMURA ETSUJI
IPC: C22B34/12
Filed: 1983-03-04
Abstract: PURPOSE:To make the disassembly and assembly of a titled device easier, the construction cost lower and the function better by adopting a sealing por structure to shut off the passage in an intermediate connecting part which couples a reaction chamber for reducing the chloride of a high-melting high-toughness metal and a condensing chamber. CONSTITUTION:A melt 80 of a sealing material is introduced through a conduit 39 into a pot 36 and is solidified. A retort 10 is heated by a heating furnace 90 to melt the Mg charged preliminarily therein. A high-melting high-toughness metallic chloride is introduced through a conduit 61 in the furnace and is brought into reaction with said melt, thus forming a sponge-like metal. After the by-produced MgCl2 is discharged through a plug 14, electricity is conducted to the heater 70 of an intermediate connecting part 30 to melt the sealing material in the pot 36 and is discharged through a pipe 37. Air is then removed through a conduit 41 and the cooling chamber 40 for the condensing chamber is cooled to evaporate the MgCl2 in the sponge metal and unreacted Mg which are captured in a condensing cylinder 50. The sealing material is again introduced into the pot 36 to solidify and the cooling chamber including the part 30 is removed from the furnace 90. After the cooling, a bottom plate 23 is removed and the formed metallic sponge is taken out.

Filed: 1983-03-04
Abstract: PURPOSE:To enable protection of articles to be soldered against the thermal impact of molten solder by providing means for forming vapor atmosphere which covers the surface of the solder liquid with a high boiling liquid and filling the space above the high boiling liquid with the vapor thereof. CONSTITUTION:When, for example, a semiconductor device 14 as an article to be soldered is inserted into a frame body 10 through the opening on the upper side thereof, the device passes first the inside of the vapor of a high boiling liquid 11, for example, florinate vapor 12 before the device contacts with jet solder 9. As a result, the device 14 is first preliminarily heated by the heat of the vapor 12 having the temp. lower than the temp. of the solder 9 and thereafter the device contacts with the solder 9 having a high temp. Since the device no longer receives sharply the thermal impact by the high temp. of the solder 9, the generation of a crack in the package and sealing glass of the device 14 by the thermal impact is obviated and the decrease in reliability owing to leakage is prevented. The device 14 is not immediately exposed to the outdoor air and is slowly cooled in the stage of taking out the device after the deposition of the solder thereon.

IPC: H01L29/84
Filed: 1990-02-15
Abstract: PURPOSE:To form a boundary stress-strain layer on the boundary between a semiconductor substrate and a film being different in a thermal expansion coefficient from the semiconductor substrate and thereby to prevent substantially the breakdown of a recessed part even when a pressure is applied to this part, by providing this film on the surface of the recessed part of the semiconductor substrate. CONSTITUTION:A metal impurity is diffused in a silicon wafer 1 by heat treatment and then a nitride film 8 having a thickness of about 1mum is formed by CVD on the rear side of the silicon wafer 1 including the surface of a recessed part for forming a diaphragm part 7. When the wafer 1 is coold to a normal temperature after the formation of the nitride film 8, an interface stress-strain layer 100 having no dislocation is formed on the boundary between the silicon wafer 1 and the nitride film 8 due to the difference in a thermal expansion coefficient between the silicon wafer 1 and the nitride film 8. When a semiconductor pressure sensor is employed in a high temperature, the metal impurity 100 to cause a crystal defect is subjected to segregation by the gettering action of the boundary stress-strain layer 100, according to this constitution, and thereby the breakdown of the diaphragm part 7 being thin the thickness is prevented when a pressure is applied to the recessed part.
