IPC: B22C9/10
Filed: 1980-11-13
Abstract: PURPOSE: To easily remove a covering material, by using a hollow core grid whose outer periphery is covered with the prescribed covering material and disintegrating the covering material after a molten metal is poured into the mold by means of the difference in temperatures of the core grid and the casting after a cold fluid is passed through the hollow section.  
     CONSTITUTION: A hollow tube 8 made of metal is formed by winding up a wire 13 spirally, and the outer periphery of the tube 8 is covered with a covering material 9 composed of a low heat conductivity brittle material, such as ceramics, etc. The hollow tube 8 is used as a core grid and castings are made after the hollow tube 8 is installed throughout the mold. After the casting is completed, a low temperature fluid, such as water, air, etc., is poured into said hollow tube 8 and a large temperature difference is generated between an inner wall 11 and an outer wall 12 of the covering material 9, and then, the covering material 9 is self-broken by means of strains generated by the internal stress due to the temperature difference. After the covering material 9 is broken, said hollow tube 8 is pulled out and, at the same time, the covering material 9 is removed.

Title: Buried pipe labeling system
Inventor: SATOU KIMIATSU
IPC: G01V3/00
Filed: 1993-06-29
Abstract: PURPOSE:To extend the communicating distance of a buried pipe labeling system when the system communicates with a buried pipe in case the system uses a heating line as an antenna by providing a probing device which transmits electromagnetic waves and a labeling device attached to the buried pipe. CONSTITUTION:The loop coil (heating line) 210 of a labeling device generates modulated signals upon receiving modulated waves. An IC element 240 for data carrier starts operations upon receiving the modulated signals without loss through a transformer 220 and stores burying information after demodulating the information from the modulated signals. When the writing of the information is completed, the element 240 generates a carrier signal. The coil 210 transmits a carrier when the coil 210 receives the carrier signal without loss through the transformer 220. A probing device 100 displays the reception of the carrier. Therefore, the operator can recognize the updating of the burying information. Since the coil 210 can transmit and receive the signal to and from the element 240 in such a way, the labeling device 200 can extend its communicating distance to the probing device 100.

Title: Conditioning device of charged particle beam accelerating tube
Inventor: KASAHARA HARUO
IPC: H01J37/147
Filed: 1989-06-21
Abstract: PURPOSE:To prevent roughening of an electrode surface on the lower electric potential side due to the discharge between adjoining electrodes by preferentially applying voltage for conditioning only between specified electrodes, in the same direction as in used. CONSTITUTION:At the time of conditioning, each electrode 1a-1f is connected to a power source 7 for conditioning through a connection switching circuit 6. In the drawing, the conditioning between electrodes 1a and 1b is depicted, in which electrodes 1b-1f are commonly connected together by the connection switching circuit 6. An electric field of the same direction as in use is thus applied between the electrodes 1a and 1b, whereby conditioning is performed. As the voltage is applied between the specified electrodes in the same direction as in the normal use, through the discharge during conditioning, roughening of the electrode surface on the lower electric potential side can be prevented.

Title: Mis type semiconductor light emitting device
Inventor: TABUCHI KAZUO
IPC: H01L29/43
Filed: 1980-11-11
Abstract: PURPOSE:To prevent Au film separation at the time of wire bonding by a method wherein a substrate is sequentially covered with films of SiO2, Cr, and Au,  and then partially with an Al film. CONSTITUTION:Cr easily reacts with SiO2 at 450 deg.C, producing CrSi2. At temperatures not higher than 450 deg.C, the reaction proceeds slowly. Cr, in addition, adheres well to Au. Accordingly, an SiO2 film 6, Cr film 7, and Au film 8 stick to each other well. The Au film 8, together with the Cr film 7 whose resistivity is relatively high, can be made thin enough to transmit light with efficiency and, further, a wire 10 can be bonded to a sufficiently thick Al film. The wire bonding work does not cause the Cr film 7 and the Au film 8 to separate from each other.

Title: Manufacture of rare earth element-fe-b series alloy magnet powder
Inventor: TAKESHITA TAKUO
IPC: B22F1/00
Filed: 1988-06-28
Abstract: PURPOSE:To manufacture rare earth element-Fe-B series alloy magnet powder having excellent magnetic characteristic at high yield by occluding H2 into the alloy containing rare earth element, Fe and B as the main components and successively cooling after executing H2 removing treatment under specific condition. CONSTITUTION:An ingot or powder of the alloy having the rare earth element containing Y, and Fe and B as the main components is held at 500-1,000 deg.C under atmosphere of H2 gas or mixed gas of H2 gas and inert gas, if necessary after homogenizing treatment at 600-1,200 deg.C, to occlude H2. Then, it is desirable to execute H2 occlusion under pressure or partial pressure of H2 gas at 10-760Torr. Successively, the H2 removing treatment in the H2 storage alloy is executed at 500-1,000 deg.C under vacuum or the inert gas atmosphere up to <=1X10<-1>Torr the pressure or the partial pressure of H2 gas. Then, if necessary after executing the heat treatment to the alloy at 300-1,000 deg.C, it is cooled.

Title: Windmill device
Inventor: HASUI HIROSHI
IPC: F03D3/04
Filed: 1982-09-14
Abstract: PURPOSE:To allow a windmill to be driven at a low air speed, by surely catching wind blowing against an area remarkably larger than a projected area of a windmill body. CONSTITUTION:Assuming that wind is blowing from a lower portion, wind present in the range as depicted by (b), (b'), (c') and (c) is caught by wind introducing plates 17 and fixed guides 6, and a wind passage 20 is gradually reduced in width during pass of wind through three wind introducing passages 20, 20' and 20''. In reverse proportional to the above, air speed is increased, and wind blows against wind receiving surfaces of brackete 2 to rotate the backets 2 by wind pressure. The wind is inversed in a direction as depicted by arrows, and flows out in a direction of a back surface of backet guides 4 adjacent to the backets 2. However, the wind does not blow against the entire surface of the wind receiving surfaces of the backets 2 because of the provision of the backet guides 4, while the inversed wind does not collide with the entering wind, but is separated by the guides 4 to flow out, thereby preventing disturbance to an entering air speed. Further, when an air speed increases to a value higher than a predetermined level, a counterclockwise rotational force created by deviation of a rotary shaft 7 overcomes a tensile force of a spring 9 to rotate a movable guide 5 to a position 5a as shown by a phantom line, thereby gradually reducing the width of the wind introducing passage 20 to limit entry of wind.

Title: Setting car speed indicator for constant speed control
Inventor: MITAKE YOSHIMITSU
IPC: B60K31/00
Filed: 1983-08-31
Abstract: PURPOSE:To indicate the setting car speed even after temporal release of constant speed travel and to eliminate anxiety of driver through easy-to-see indication by providing an indicating circuit to be driven by the output from an oscillator then driven by the output from following signal forming circuit. CONSTITUTION:A timer 10 is started by the setting signal (a) of constant speed travel controller to feed an output signal (b) only for predetermined time. Following signal forming circuit 13 will not function during function of timer 10, thereby the output signal (d) of AND gate 12 is fed to an indicating circuit 15. Consequently, light emission body 32b in second indicating section will flicker with the repeating period of frequency division signal (c) in frequency division circuit 23 to notice the setting car speed to the driver. Upon stoppage of timer 10, said circuit 13 is turned on but since one of the input logic of AND gate 12 is 0, the output logic will also be 0. Consequently, the light emitting body 32b is lighted continuously by the output signal (e) of said circuit 13 to indicate the setting car speed continuously.

Abstract: PURPOSE:To avoid the recording beyond the width of the recording paper, by using the recording paper having a smaller width than the maximum width of paper of a device main body and recording the recording data in plural divisions on the recording paper. CONSTITUTION:The numerical data supplied from a keyboard 5 is controlled by a CPU6, and the recording equivalent to the width of the recording paper is stored in a register 8. The recording equivalent to the paper width is carried out on the recording paper by a printer 9. At the same time, a counter 10  counts the frequency of key inputs of the keyboard 5, and the count contents is compared with the paper width detection signal of an encoder 12 through a comparator. If the width of the recording paper can record 6 digits, a comparator 11 transmits a coincidence signal to a CPU6 when the count contents of the counter 10 reaches 6 and stores the record data of 6 digits in the register 8 to perform the recording of 6 digits. When the recording is over, the recording paper is fed by a line. At the same time, the counter 10 is reset by the above- mentioned coincidence signal. And the next key input is counted again from the start.
