Title: Living body information measuring apparatus
Inventor: MINAMI SHIGETOSHI
IPC: A61B10/00
Filed: 1994-12-05
Abstract: PURPOSE: To provide a living body information measuring apparatus which enables measuring of a heart beat of a fetus with a simple operation. CONSTITUTION: A cardiac sound of a mother is detected by a dedicated microphone 1 for detecting cardiac sounds arranged separately from a microphone 1 for detecting cardiac sounds of fetuses. After the inversion of a heart heart waveform of the resulting mother cardiac sound signal S1, an opposite phase waveform adder 7 adds the waveform to a fetus cardiac sound signal S2 containing the cardiac sound of the mother as detected by the microphone 1 for detecting cardiac sounds of fetuses to remove the waveform attributed to the cardiac sound of the mother. This enables the picking up of a heart beat of the fetus alone thereby measuring the heart rate of the fetus accurately.

Title: Patterned roll
Inventor: YAMAGUCHI SHUICHI
IPC: G03B21/62
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a desired shape without spending much time for fabricating fine grooves by forming helical groove on the surface of a roll. SOLUTION: Fine grooves are formed, in a single strip or multistrip helical shape, on the surface of a patterned roll 1 and the helical angle is set depending upon the use applications of an optical sheet and the groove is of a V or U-shaped. The matrix of the patterned roll 1 is tool steel with a specified outside dia. and a specified length shaped like a roll. In addition, the surface of the patterned roll 1 is plated with a hard copper, for example, which is somewhat less durable than a non-electrolytic nickel-plated face but reduces the wear of a cutting tool. After cutting the surface, it is treated by plating a non-electrolytic nickel as a protecting film to a specified thickness, on the cut surface, so that the surface hardness and the durability are adequately secured without collapsing the groove shape.  Thus a continuous cutting fabrication process can be employed by forming the groove helically and the switching of cutting, rough and finish fabrications for every working pitch and the tool replacement are dispensed with. Consequently, the groove can be fabricated in the continuous cutting mode and also the edge wear of the cutting tool can be reduced and further, the manufacturing time can be shortened significantly.

Title: Jumper device
Inventor: YOSHIDA TOSHIHIRO
IPC: H02G7/20
Filed: 1992-11-18
Abstract: PURPOSE:To prevent a mechanical damage to a jumper device and the occurrence of a flashover between the arm of a steel tower and rigid member by supporting the rigid member by means of a plurality of supporting members arranged at intervals in the length direction of the rigid body so that the vibration of the rigid body in the length direction can be suppressed even when galloping, etc., takes place. CONSTITUTION:Supporting members 2 support both ends of a rigid member 1. In addition, the member 1 is extended by respectively fixing extension members 10 to both ends of the member 1 and one ends of supporting members 12 are fitted to the ends of the members 10. The other ends of the members 12 are fitted to insulator string yokes 4. As a result, the member 1 is restricted in movement in its length direction due the pulling forces of the plurality of supporting members 2 and 12, since both ends of the member 1 are supported by the members 2 and 12 at intervals. Therefore, the vibration of the rigid member in its length direction can be suppressed and, accordingly, a damage to a jumper device and the occurrence of a line-to ground fault can be prevented.

IPC: H01L29/786
Filed: 1990-11-28
Abstract: PURPOSE:To allow the sufficient supply of voltages from a scanning signal driving circuit to picture element TFTs and to improve a display grade by forming the N channel TFTs among the TFTs constituting the scanning signal driving circuit to a dual gate structure and executing counter driving. CONSTITUTION:The N channel TFT among the TFTs of the CMOS logic part and buffer amplifier part constituting the scanning signal driving circuit 1 forms the structure in which two pieces are connected in series and a gate electrode is commonly used. In addition, the pulse voltage of a reverse polarity is impressed to the counter electrode of a display part 3 when the TFT of the display part 3 is on. The amplitude range of the voltage to be impressed to a liquid crystal is so regulated as to be larger than the amplitude range of the output voltage from a data signal driving circuit 2. The pulses of the sufficient voltage amplitude are outputted to a scanning signal line 5 in this way and the amplitude of the output voltage to the scanning signal line is diminished while the display grade is well maintained by executing the counter driving.

Title: Method for thermal spraying on surface of roll
Inventor: SAWA MASAAKI
IPC: B23K13/01
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of sprayed coating, while a roll is rotated in the circumferential direction of a barrel, by heating and softening its surface by high frequency heating and executing thermal spraying. SOLUTION: While a roll 7 is rotated in the circumferential direction of a barrel, the opposite side of the roll is heated by a high frequency induction heating work coil 8. In the surface part of the roll 7, hardness reduces, and it is softened. Cermet, ceramics or metallic atoms in a thermal spraying material 6 eat into the surface of the roll 7, and, by an anchor effect, the adhesion of sprayed coating improves. Since high frequency heating is adopted, only the surface of the roll 7 is heated in a short time, and, as for the inside of the roll 7, heating is not executed to prevent the generation of thermal distortion in the roll 7. In accordance with the movement of a thermal spraying gun 1, the high frequency heating work coil 8 is moved in the width direction of the roll 7, and the whole body in the width direction of the roll 7 is applied with thermal spraying.  Its durability can be improved while the function of the roll 7 is securely shown.

IPC: D06F58/10
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To perform drying similar to natural one in a short time. SOLUTION: This drier is constituted such that hated air current is circulated in a drying chamber 4 to dry the washing 2. Then, during the circulation of the heated air current under the closed condition, a time taken for saturating the drying chamber with moisture evaporated from the washing 2 is selected according to one's own judgment to exhaust the atmosphere containing much moisture in the drying chamber 4 while introducing the open air. Thus, superfluous moisture is immediately exhausted while the washing are steamed and dried to shorten the drying time.
