Abstract: PURPOSE:To improve drain withstand voltage of a transistor by making thicker a drain region than a channel region constructed into a thin film having the same impurity concentration as the channel region and a width less than a depleted maximum distance of the channel region, between the channel region and the drain region. CONSTITUTION:An SiO2 insulating film 12 having a protruded portion is deposited on a single crystal Si substrate 11 at the center of the surface of the same, and there is formed a silicon-on-insulation type MOS transistor 13 comprising a single crystal and having excellent characteristics such as low stray capacitance. Then, a gate electrode 5 is provided on the protruded portion of the film 12 through a gate oxide film 14, and there are located drain and source regions 17 and 18 constituting the transistor 13 on opposite sides of a channel region 16 located under the electrode 15 putting the channel region 16 therebetween. With such arrangement, thickness T1 of the region 16 is defined as T1>=2[epsilonphiF/(qNs)]<0.5> where epsilon is a dielectric constant, F is Fermi energy eV, q coulomb is the amount of basic charges, and Ns is impurity concentration. Further, thickness T2 of the regions 17, 18 expressed as T2>T1 is obtained.

Title: Arithmetic unit for speed
Inventor: OOE HIDEMI
IPC: G01P3/489
Filed: 1981-06-30
Abstract: PURPOSE:To compute a speed signal quickly and easily with a simple construction by accessing a speed table with a microcomputer employing a clock pulse count as address according to the speed with a counter. CONSTITUTION:Clock pulses are counted with a counter 1 during one cycle of rotational pulses and the count thereof proportional to the speed of the counter 1 are used to access a speed table 2a contained in a microcomputer 2 therethrough for calculation of speed signals. On the other hand, when the count of the counter 1 is larger than the specified volume, it is shifted l times sequentially to lower bits and converted to 1/2Xl with the computer 2 so that it is kept within the specified value to access the table 2a. Information read out is multiplied by 2l to compute the speed with the computer 2. This eliminates multiplier/divider circuit and the like thereby enabling quick and easy calculation of speed signals with a simple construction.

Title: Welding device
Inventor: FUKUDA TAKUO
IPC: B23K31/00
Filed: 1978-08-16
Abstract: PURPOSE: To weld metal plates while revolving a pipe and fabricate the same to involute form by aligning the uppermost layer of the laminated metal plates to the axial center of the pipe.  
     CONSTITUTION: The laminated steel plates 2 are made to the height at which the steel plate of their uppermost layer aligns to the plane passing the axial center of a pipe 1. Next, while a table 14 is being gradually moved upward at a constant speed, the end edges of the inner side of the respective steel plates 2 and the outside of the pipe 1 are subsequently welded. Then, the welded steel plates 2 detach by subsequently turning from the laminated positions along with the revolution of the pipe  1. When the pipe ends one turn, the steel plate of the lowermost layer is welded,  thus the respective steel plates 2 are fabricated to the pipe 1 radially without producing any gap.

Title: Drive system of delta connection three-phase motor
Inventor: SAKURAI MIKI
IPC: H02P27/06
Filed: 1994-04-04
Abstract: PURPOSE:To reduce noise and vibration when driving a delta connection three- phase motor by adding properly combined pulse voltages to a delta connection three-phase motor and bringing the phase current waveform of a motor coil winding closer to a fundamental sinusoidal waveform. CONSTITUTION:Properly combined pulse voltages 10 are added to a delta connection three-phase motor 5 and a phase current waveform 9 of a motor coil winding is brought closer to a fundamental sinusoidal waveform. The properly combined pulse voltages 10 do not depend on the pulse width modulation system and are obtained by combining the a power supply voltage 2 (H), a grounding voltage 3 (L), and an open voltage by considering the operating characteristics of the delta connection three-phase motor 5. Therefore, a current closer to a sinusoidal waveform equivalent to the phase current waveform 9 flows in terms of a terminal current 4, thus causing three-phase current to flow in an improved balance and hence reducing noise and vibration when driving the delta connection three-phase motor 5.

Title: Multicolor printing method for thermal printer
Inventor: MIYAWAKI SEIJI
IPC: B41J2/32
Filed: 1986-04-30
Abstract: PURPOSE:To shorten a printing time, by moving a printing head in printing directions and thermally transferring two colors through the reciprocation of the head. CONSTITUTION:While moving a printing head 1 from the left end to the right end of a transfer recording paper 4, a first color 5 is thermally transferred onto the paper 4. Next, a multicolor ink ribbon 3 is taken up so that a second color 6 is located on a platen 2, when the head 1 thermally transfers the second color 6 onto the paper 4 while returning from the right end to the left end of the paper 4. Namely, the head 1 is reciprocated one time during printing in the first color 5 and the second color 6. The head 1 is again located at the left end on thermally transferring the second color 6. Then, the ribbon 3 is taken up so that a third color 7 is located on the platen 2, and the third color 7 is thermally transferred while moving the head 1 toward the right end of the paper 4. Thus, thermal transfer of four colors is conducted by only two reciprocations of the head 1, and accordingly, printing time is shortened.

Title: Velocity setting device for magnetic head
Inventor: TASHIRO KEIZOU
IPC: G11B5/55
Filed: 1978-08-17
Abstract: PURPOSE: To eliminate the discontinuation of the driving current at the speed reduction time by generating several units of pulses every time the magnetic head passes through a track and then varying the velocity setting signals with every counting of the generated pulses, thus preventing occurrence of the vibration and the noise at the mobile part.  
     CONSTITUTION: The position signal is applied every time the magnetic head passes through one track, and the pulses are generated through comparator circuit 12 and mono-multi 14. At the same time, the pulses are generated through comparator circuit 13 and mono-multi 15 with inversion at inverse amplifier 11. The both pulses are supplied to OR circuit 16 to obtain the logic sum and then integrated through integrator 17. Based on this output, the pulses are generated at comparator circuit 18 and mono-multi 19 to obtain the logic sum at OR circuit 20 with the pulse from circuit 16. For the subtraction, the shift track number is set previously to subtraction counter 21 via the shift track number setting signal. When the contents becomes lower than a fixed level, the contents of counter 21 is displayed directly at the output of gate 23a...to be supplied to DA comparator 24. As a result, the output is reduced by a fixed level, and the velocity setting signal is generated through  square root circuit 25.

IPC: B65G17/10
Filed: 1992-03-26
Abstract: PURPOSE:To remove a harmful influence by the inclusion of an article to be carried completely by positioning a clearance between aprons higher than the position of the article to be carried.

Title: Dual curl removal device
Inventor: KUO YOUTI
IPC: G03G15/00
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To reduce curl by selectively operating two adjacent curl removal nips or not operating both of them. SOLUTION: Two pairs of drive rolls 204, 304 and pinch shafts 202, 302 are arranged opposingly to form a bending nip. A clearance between two opposing nips forms a linear paper path. Shafts of two drive rolls 204, 304 are fixed on a side frame. However, two opposing pinch shafts 202, 302 are connected by two end caps so that they can move vertically for the drive rolls. Consequently, the first pair forms the bending nip which bends insertion sheet curled upward reversely for engagement, and an end cap moves to form a first nip, thereby opening the second pair.
