Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent radiation area from decreasing by a condensed coolant remaining in a coolant passage. SOLUTION: This device has a coolant tank 3, provided with heating units 2 and a radiator 4 for condensing and liquefying coolant vaporized in the coolant tank 3, the radiator 4 having a flow-in communicating part 44, a flow-out communicating part 45, a coolant passage 42, and inner fins 391 provided in the coolant passage 42.

Abstract: PURPOSE:To prevent the loss of a cursor while an operator is recognizing the cursor by shifting the cursor with the control of a computer system, etc., displaying largely the cursor toward its shifting point when the shift value is large or the shift speed is high, and enabling the operator to visually recognize the cursor. CONSTITUTION:A cursor display device 10 displays a cursor 7 on a display 2 based on the contents of the X coordinates 11a and the Y coordinates 11b which show the present position of the cursor. The cursor 7 is shifted to an optional coordinate point continuously or at a jump with the control instruction of a computer. In this case, however, the cursor is displayed long and largely for several seconds after its shift as shown by a dotted line. In other words, the computer shifts the cursor 7 to an optional coordinate point and then displays the cursor 7 long and largely as shown by the dotted line if the shift value of the cursor 7 is larger than the prescribed value. Thus an operator can easily recognize the position of the cursor 7, and the loss of the cursor 7 is prevented.

Abstract: PURPOSE:To reduce unevenness at the interface between a second insulating film and first non-single-crystalline silicon film and to increase the withstanding voltage of the second insulating film, by irradiating light having a plural of wavelength onto the first non-single-crystalline silicon film before forming the second insulating film. CONSTITUTION:On the surface of a P<->-type silicon substrate 21, a field oxide film 22 is formed, and then a first thermal oxidation film 23 is formed. Next, a first polycrystalline silicon film 24 is deposited. At this time, phosphrus is doped while PH3 gas is flowed. When the depositing temperature is below 580 deg.C, or below 560 deg.C to make the ratio of amorphous portions large or to make amorphous, the surface can be more smoothly formed on thermal oxidation after lamp irradiation. Next, after a CVD oxide film 25 is deposited on the entire face, it is irradiated in two steps with halogen lamp light. The CVD oxide film 25 serves for preventing occurrence of unevenness by applying pressure to the first polycrystalline silicon film 24.

IPC: C23C14/14
Filed: 1982-05-31
Abstract: PURPOSE:To prevent an Fe-Ni metallic magnetic film from exfoliating during a heat treatment, by employing as a substrate a non-magnetic material represented by the formula, ZnxMn2-xNiO3 (0<=x<=1). CONSTITUTION:ZnO, MnO and NiO are weighed, mixed together and ground in water and then calcinated at 700-1,200 deg.C before being formed by means of a mold. Then, the mixture is sintered at 1,150-1,300 deg.C in N2 to prepare a material represented by the formura, ZnxMn2-xNiO3 (0<=x<=1). This material has the NaCl structure. The material is mirror-finished and provided with an Fe-Ni metallic magnetic film by sputtering and then annealed. The substrate formed in accordance with this constitution is equal in thermal expansion coefficient to the Fe-Ni metallic magnetic film; therefore, any desired annealing can be effected without any possibility of exfoliation. In addition, since the substrate has a hardness substantially equal to that of the magnetic powder in a magnetic tape, it is made possible to construct an excellent thin film magnetic head.

Then the output signal of a signal source 13 is outputted from a terminal 17 after amplification 14. It the grounding current amplification factors of emitter-grounded transistors(TR) Q1-Q3 is beta, an electric current of I1/2beta is made to flow to the base of the TR Q2 which is the negative input terminal of the amplifier 14 and an offset of R1I1/2beta is produced as compared with the DC potential at an output terminal. When the circuit 18 is set to another amplifier 12 side, on the other hand, another constant-current source 20 is driven and the output signal of another signal source 11 is outputted from the terminal 17. In this case, an electric current of I1/2beta is made to flow to the base of the TR Q3 and the DC potential at the negative input terminal of the amplifier 14 offsets by R1I1/2beta as compared with the DC potential at the output terminal.

Finally, the cross connect between an input end (g) and an output end (h) of the reception end cross connector 40 is changed to the cross connect from the the input end (y) to an output end (h.) Thus, the erroneous transmission is eliminated.

Abstract: PURPOSE:To efficiently transfer the status information to the arithmetic controller, by installing a selector which selectively outputs the status information of the input-output device to the input-output controller and a register which holds the status information. CONSTITUTION:When an input-output instruction is outputted from an arithmetic controller to an input-output controller 4, apparatus select signals UL1 and UL0 assigned from the controller 4 are outputted to I/O UNs 0-3 and a selector 10, and ready signals RDY0-RDY3 from prescribed I/Os are selectively inputted into the unit 4 through the selector 10, and thus, the processing is executed. This processing is performed only for a preset time.

After a prearranged time, a reset signal FWCLR is inputted into the controller 4 through a gate 30 and the processing for the 1st I/O is temporarily stopped, and then, the processing for the 2nd I/O is performed for a prescribed time. After the Prescribed time has passed, the processing, for the 1st I/O is again started.

Abstract: PURPOSE: To record excavation data simply and definitely by installing to an excavating machine sensors which detect such excavation data as depth, rotary speed, torque and hydraulic pressure and so forth and installing a personal computer or the like which computes and edits the aforesaid excavation data. CONSTITUTION: Various kinds of sensors 2, such as a rotary encoder, a pressure sensor, and a flow rate sensor are installed to an excavating machine 1, thereby detecting depth, advancing speed, advancing force, impact force, number of impact, hydraulic pressure and flow rate and so forth.

An operator of the excavating machine 1 can execute this recording work in parallel to an excavating work only by setting a non- contact type recording medium, thereby dispensing with any people for data recording. This construction makes it possible to compile data even under such adverse environments as dust, vibration and high temperature.  It is, therefore, possible to record data simply and definitely as well.
