Title: Semiconductor device
Inventor: OGURA MOTOTSUGU
IPC: H04N5/335
Filed: 1986-07-22
Abstract: PURPOSE:To obtain good matching of Si for a manufacturing process and reduce cost, by laminating distorted super lattice layers comprising two or more species of II-VI semiconductors on a surface which is formed on one main surface of a semiconductor substrate and which contains insulating materials and metallic materials. CONSTITUTION:By organic metal vapor growth method (MOVPE method), for example, a distorted super-lattice 8 made of ZnTe and CdTe is formed as a base of single crystal epitaxy, and then hetero junction comprising single- crystal thin films 9 and 10 made of p-type ZnCdTe and n-type ZnSe is formed thereon. Because both ZnCdTe and ZnSe on this groove are single crystals, and not shaped in ice columns, they have no trouble on water and organic washing, without their remnants generated by removal of photo-resist, so that this processing can be pretty easily done. Besides, sensitivity, because of single crystal, becomes extremely high, and this device becomes twice or more excellent in characteristics compared with the conventional ones.

IPC: H04B1/26
Filed: 1979-12-26
Abstract: PURPOSE:To prevent erroneous search operation, by setting the holding time of a holding circuit equal to the lock time of PLL. CONSTITUTION:Latch circuit 92 sets the value of frequency dividing ratio N from controller 12 as a time-division signal. For this purpose, counter 120 is divided into parts 120-1, 120-2 and 120-3, which are synchronized with timing signals T1, T2 and T3 by AND gates 121-1, 121-2 and 121-3 to send the frequency dividing ratio N value of counter 120 to a frequency divider. Frequency divider 9 performs sampling by AND gates 94-1, 94-2 and 94-3 with timing signals T1.t, T2.t and T3.t and stores frequency dividing ratio N in latch circuits 92-1, 92-2 and 92-3 divided corresponding to counter 120. Although the value of ratio N of latch circuit 92 has a discontinuous part generated during a search, the discontinuous part is detected by detecting circuit 122 and holding circuit 123 and until the output of holding circuit 123 is ceased, frequency conversion triggering and search stop detection are invalidated.

Title: Hydraulic impact type drilling device
Inventor: HONDA TOSHIYUKI
IPC: E21B1/28
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To improve strength by forming a drain passage among a housing, a control valve chamber and a cylinder, and making a piston solid. SOLUTION: When a piston 6 strikes a drill bit 4, an impact passage 15 and a drain passage 14 are connected, and a piston driving chamber 16 becomes low in pressure, while a cylinder lower part high pressure chamber 13 becomes high in pressure due to the passage 14. The piston 6 then ascends, and a feed water passage 12 and a signal passage 17 are connected. A lower part pressure receiving part 11 becomes high in pressure, and a control valve 9 ascends. Water in a chamber 16 thereby spouts out from a center hole 5 of the drill bit 4 through the passages 15, 14. A passage 12 and the passage 15 are then connected to make an upper part pressure receiving chamber 7 high in pressure, and the piston 6 descends to strike the drill bit 4.  A passage 17 and a low pressure chamber 21 are connected, and a control valve driving chamber 18 becomes low in pressure so as to make the control valve 9 descend. A center through hole of a conventional piston is thereby eliminated, and the drain passage 14 is arranged small. The cross-sectional area of the piston 6 is thereby enlarged so as to increase the strength of an impact part.

Abstract: PURPOSE:To obtain more kinds of control signal with a small amount of control bit data, and surely execute a decoding by making a decoder receive the bit of a prescribed figure position according to a latch signal, decoding it, and selectively operating one of plural control data latch circuits. CONSTITUTION:A control data latch circuit 14 is provided at a control subject correspondence, and one of them is selectively operated by decoding the signal of the prescribed figure position of a control data. Then, in a control signal decoding circuit 10, the bit number of the control data can be reduced for the amount of decode bit number. Also, the space is made small by resetting a latch bit by the opposite edge of a clock signal, so an accurate control data can be transferred to the desired control data latch circuit 14 from a shift register 11. Thus, there is no need to take the bit number of the control data latch circuit in the control signal decoding circuit for the amount of bit number transferred from a CPU 1, and more kinds of serial codes can be surely obtained.

Abstract: PURPOSE:To obtain a highly accurate resistance element which has low parasitic capacitance and high breakdown strength and then, cuts off the occurrence path of alpha ray soft errors by making desired regions have the first and second insulating films. CONSTITUTION:Desired regions which are provided at least at two places on a single crystal substrate 1 are equipped with the first insulating films 5 which are isolated by the single crystal substrate and are in contact with parts of side walls of the desired regions and, then, reach the single crystal substrate and, further, are perpendicular to the single crystal substrate as well as the second insulating film 8 which are prepared at the bottom face of the desired regions. Accordingly, active elements, such as a transistor and the like are constructed by causing them to be adjacent to the foregoing insulating films. Further, once a resistance is manufactured as a semiconductor element, a resistance element which is not very much dependent upon an operating temperature in the same way as that found for the resistance elements in conventional semiconductor substrates is obtained. Moreover, the region of the resistance element is regulated by insulators 6 and deeply grooved insulating films 5 filling horizontal and vertical pits 8 and 5; besides, its region is isolated completely from the semiconductor substrate. In this way, the depth of an impurity diffusion layer is not expanded by heat treatment during a manufacturing process and an introduction path of alpha ray soft errors is cut off completely.

Title: Treatment of radioactive waste
Inventor: SAKURAI MANABU
IPC: G21F9/12
Filed: 1987-07-13
Abstract: PURPOSE:To save a radioactive material adsorbent by cleaning the used radioactive material adsorbent with a sulfuric acid soln. and reusing the same. CONSTITUTION:The radioactive material adsorbent 2 in a column is laminated in packed layers 3 of upper, middle and lower stages 3A, 3B, 3C. The adsorbent 2 adsorbs the radioactive material from the radioactive fluid flowing therethrough and the radioactive fluid which is thereby decreased in the dose is discharged from an outlet 1b. The adsorbent 2 packed in the respective packed layers 3 increases its adsorption dose by adsorbing the radioactive material in the fluid. Said adsorbent is handled as the used radioactive material adsorbent 2a after a prescribed volume of the radioactive fluid is passed therethrough. The radiation dose of the adsorbent 2a exhibits a max. value in the upper layer 3A near the inlet 1a and a min. value in the lower layer 3C near the outlet 1b. Since the adsorbent 2 packed in the upper layer 3A has a high dose, the adsorbent is subjected to a prescribed treatment and is stored as the radioactive waste. The adsorbent 2a in the middle and lower layers 3B, 3C has a relatively low dose and is, therefore, cleaned with the sulfuric acid soln. to decrease the dose. The cleaned adsorbent is reused as the regenerated adsorbent. The adsorbent 2 is thus saved.
