Inventor: IWASAKI HIDEJI
IPC: C07B61/00
Filed: 1995-03-28
Abstract: PURPOSE: To industrially, efficiently and inexpensively obtain 2,3-dimethyl-2- butene useful as a raw material for a perfume, an agrochemical, etc., by isomerizing 2,3-dimethyl-1-butene in the presence of a prescribed derivative in a vapor phase without causing danger in a reaction, environmental pollution, etc. CONSTITUTION: This compound is obtained by isomerizing (B) 2,3-dimethyl-1- butene in the presence of (A) magnesium oxide as a catalyst. For example, the reaction is carried out by supplying 0.01-100 pts.wt., especially 0.1-20 pts.wt. of the component B based on 1 pt.wt. of the component A per unit time to a vapor-phase reactor containing the component A at 100-500 deg.C, especially 150-300 deg.C under atmospheric pressure.

Title: Heater for single crystal pulling-up device
Inventor: HORIO TAISHIN
IPC: H05B3/14
Filed: 1995-03-27
Abstract: PURPOSE: To provide heater having a structure joining the heater body and a thermal section for power supply thereto, designed to prevent silicon, etc., from intruding into the joint by furnishing the heater body above the joint with a flow circulating part. CONSTITUTION: The amount of silicon, etc., adhered to the heater body is increased due to repeated use of a single crystal pull device and sags are developed, and even in case such impurities are creepingly allowed to go down toward the terminal section of this heater, since a flow circulating part is furnished on the body above the joint, the flow circulating part serves as a penthouse, stopping the above-mentioned creeping of the impurities and thus preventing the impurities from intrusion into the joint. Even if the amount of silicon, it falls right under from the tip of the flow circulating part, thus avoiding the intrusion into the joint. The figure illustrates the sectional view of this heater for a single crystal pull device. The terminal section 11 is jointed via a bolt 12 to the body 13. Above the joint, the flow circulating part 14 e.g. in a finned fashion is furnished.  Thus, even in a case that scattered silicon, etc., is creepingly allowed to go down along the body 13 and comes to the flow circulating part 14, it never comes to the joint 15.

Title: Cylindrical winding for self-cooled gas-insulated transformer
Inventor: ICHIKAWA MOTOYASU
IPC: H01F27/28
Filed: 1986-04-25
Abstract: PURPOSE:To facilitate transferring and connecting works of a self-cooled gas- insulated transformer by composing a cylindrical winding by lap connecting outer conductor on an inner conductor and inner conductor on an outer conductor at the transferring positions of the inner and outer conductors. CONSTITUTION:The insulating member of insulating coating of a first conductor 2 formed by lap winding two conductors has high heat resistance, and the insulating member of a second conductor 3 has low heat resistance. The first and second conductors 2, 3 are composed by lap connecting the second inner conductor 3 on the first outer conductor 2 by brazing and the second outer conductor 3 on the first inner conductor 2 by brazing at transferring position 7 where the inner and outer conductors at the center of a cylindrical winding 10 are transferred. Thus, since radial position is automatically displaced, the conductors may merely be axially bent, and radial conductor bending work required for high accuracy can be eliminated. Further, since the conductors are not necessarily opposed at the connecting work, the bonding and connecting work is also facilitated.

Title: Manufacture of oxide superconducting material
Inventor: YAMAZAKI SHUNPEI
IPC: C01G3/00
Filed: 1991-04-01
Abstract: PURPOSE:To form a ceramic superconducting material into a coil or plate or wire by momentarily dissolving a material and then generate single crystal or crystal growth approximated it in the dissolved region with the un-dissolved region other than the dissolved area used as a core. CONSTITUTION:A substrate 1 having formed a film 2 is irradiated with the YAG laser beam 3. Irradiation is gradually shifted to the predetermined direction 11 so that a pulse beam causes one circular spot to be overlapped in the greater part with the next circular spot. Only the part irradiated with the laser beam is selectively dissolved and after the laser beam is not irradiated, recrystalization occurs. Therefore, single crystal or the crystal approximated to single crystal of the ceramic superconducting material may be manufactured into a coil or plate or wire.

IPC: H04B1/40
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To use a local oscillation circuit in common. SOLUTION: A frequency synthesizer 105 generates a 1st local oscillation frequency for orthogonal transformation and a 2nd local oscillation frequency in the case of analog reception based on a control signal from a changeover control section 300. An orthogonal demodulation circuit including multipliers 103, 104 of a digital IF section 100 is active in the digital mode and a reception wave from a high frequency section is orthogonally transformed and the result is fed to a base band processing section. In the analog mode, a buffer 109 gets through and the 2nd local oscillation frequency is fed to an analog IF section. Similarly, a modulation section 200 uses a frequency synthesizer 206 to generate a 3rd local oscillation frequency for orthogonal modulation to drive the orthogonal modulation circuit such as multipliers 204, 205.  In the case of analog signal transmission, a frequency synthesizer 105 generates a 4th local oscillation frequency and it is frequency-modulated by an analog modulation signal and the result is outputted to a high frequency stage via the multiplier 205.

IPC: G03G15/047
Filed: 1987-04-18
Abstract: PURPOSE:To omit complicate key operation by specifying a development color according to plural input means for specifying coordinates. CONSTITUTION:A table 5 has resistance wire arranged at fine intervals in an X-axial and a Y-axial direction, an optional point is pressed to form a short circuit, and a resistance value determined by the X and Y coordinates of the optional point is detected in the form of a voltage level. Light pens 1 and 2 incorporate switches which operate by the depression of their pen tips (pressure pins) and opening/closing signals are sent to the circuit part of the tablet 5 through conductors 6 and 7. This circuit part generates a coordinate signal only when a switch is pressed. Further, a main circuit part generates a black signal when receiving the depression signal from the conductor 7 or a red signal in the case of receiving the signal from the conductor 6. An erasure key 901 specifies full erasure in a specified area and a trimming key 902 specifies full erasure outside the specified area. A clear key 903 erases an input and an end key 904 registers input data. Consequently, a development color is specified without any complicate key operation.
