Title: Method for cooling outer-fan-cooled sealed permanent magnet rotating electric machine
Inventor: NAKAMURA MASANORI
IPC: H02K9/04
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of heat from a stator by partitioning into rotor and stator core cooling parts, providing a pair of fans at both ends of a rotor core, and at the same time by providing a heat pipe in a rotor shaft. SOLUTION: Cooling air 1 generated by an electrically-driven blower 101 passes through a cooling fan 102 of an electric motor. At this time, stator and rotor core cooling parts are partitioned by shield plates 105a and 105b, thus preventing heat from being generated at the coil end of a stator coil 104 and at the end part of a stator core cooling part 103 from being moved to a rotor side. Furthermore, a pair of fans 205a and 205b are provided at both ends of a rotor core 202, and air inside the rotor is circulated. Also, a heat pipe 206 is provided in a shaft 208, and one end and the other of the heat pipe are allowed to project to the inside and outside of the electric motor, respectively, thus separately cooling each of the rotor and stator cooling parts, and hence reducing increase in the temperature of a permanent magnet.

Title: Estimation of wire capacity and designing of ic
Inventor: ITO HIROTAKA
IPC: G06F17/50
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To increase the estimation accuracy for the capacity of the wire. SOLUTION: Before determining an actual wire for connecting terminals, a path of a virtual wire is estimated using an easy method with short-circuits allowed. Congestion of wires is estimated for each of small regions A, B wherein the virtual wire exists based on the occupancy rate region of the grids. Moreover, the adjacency rate which is the ratio of the virtual wire being adjacent to the other wires, etc., is estimated as a value proportional to the degree of congestion of wires. By multiplying the increment of the capacity of the virtual wire per unit length caused by its adjacency to the other wires, etc., the adjacency rate, and the wire length of the virtual wire, the increment in the capacity of the wire caused by the adjacency can be estimated for each small area.  By adding this increment to the capacity to substrate and then calculating the sum of the increments of the capacity of the wire for all the small regions wherein the virtual wire exists, the capacity of the wire can be estimated taking adjacency into consideration.

Title: Digital signal processing circuit
Inventor: KURIHARA HIDEAKI
IPC: G06F11/28
Filed: 1986-07-18
Abstract: PURPOSE:To perform the debug with high efficiency by reading the internal data when a debug error of the firmware of a digital signal processing circuit is detected. CONSTITUTION:A digital signal processing circuit contains an instruction means 1, an internal memory means 2, an arithmetic means 3, an input/output control means 4 which controls these means 1-3, and an external memory means 5. If the means 4 receives an internal data output signal from outside when a debug error occurs, the means 4 resets an output address generating means 6 to inhibit the input/output with outside. Thus the internal data on the means 2 is outputted to the means 5 via an address designated by the means 6. Thus it is possible to refer to the debug result.

Title: Chucking device
Inventor: MATSUO SOICHI
IPC: B05C13/00
Filed: 1987-07-09
Abstract: PURPOSE:To prevent a liquid material, such as resist or the like from being introduced to the rear face of a material by providing a rear side cover separably provided from the support on the rear face of a support for a chuck body and having a flange in close contact with an extended rear face of the material at the side of the support when the chuck body approaches the support. CONSTITUTION:Since a substrate 8 is larger than the support 1a of a chuck body 1, its peripheral edge is supported in a state that it is extended outside from the edge of the support 1a. The substrate 8 is fixedly supported onto the surface of the support 1a through an O-ring 7 for attracting the substrate. The differential pressure in a cylinder bore 12a from the atmosphere overcomes the energizing force of a coiled spring 18 so that a piston member 14 is attracted into the bore 12a, a rear side cover 10 approaches the support 1a, and the upper face of a flange 10a is brought into close contact with the rear face 8a of the perlpheral edge of the substrate 8. Liquid resist is dropped on the substrate 8, which is rotated at a high speed and coated therewith. The rear face 8a of the substrate 8 is completely covered by the flange 10a to prevent the resist from being introduced to the rear face 8a of the substrate 8.

Abstract: PURPOSE:To provide large torque, by connecting a third drum to a second drum in such a manner that a rotational amount of an outer circumference of the third drum is larger than that of the second drum. CONSTITUTION:A third drum 25 is disposed in parallel with a second drum 24 in its vicinity and a first portion 27a of a string-shaped second elastic member 27 is wound at a portion where the second drum 24 is unwound out.

Further, the second drum 24 is connected to the third drum 25 in such a manner that an outer circumferential rotational amount of the third drum 25 is greater than an outer circumferential rotational amount of the second drum 24. With the arrangement, tensile distortion is produced in a first elastic member 26 and the second elastic member 27 simultaneously by a less number of drums. As a result, large torque can be provided by combining an elastic force of the two elastic members 26, 27.

Title: Method and device for expanding dynamic range including no spurious of analog-digital converter
Inventor: MYER ROBERT EVAN
IPC: H03M1/18
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain an expanded dynamic range (SFDR) which contains no spurious by converting a control analog signal into a digital signal on a 1st path for generation of a converted signal that includes a spurious distortion. SOLUTION: An A/D (analog/digital) system 10 receives an analog signal S which is converted into a digital signal, and the signal S generates the spurious of a level where the conversion of the signal S that is carried out by a 1st A/D 12 is allowed. An amplitude is secured at the outside of an SFDR of the A/D 12 to generate a converted digital signal. A limiting device 14 controls, i.e., clips the amplitude of the signal S at a step before the A/D 12 and generates an output signal S as a result including an allowable spurious distortion. A signal distortion D is generated when the amplitude of an input signal S is controlled. Then the distortion D can be eliminated from the output of the system 10 when a sample of the distortion D is sent to the preceding stage.
