Title: Controller for induction motor type electric railcar
Inventor: OKAMATSU SHIGETOSHI
IPC: B60L9/22
Filed: 1984-10-04
Abstract: PURPOSE:To reduce the AC component of a specific frequency contained in input currents by dividing a plurality of variable voltage variable frequency inverters into sets of 2 units, and regulating the output voltages of the combined inverters. CONSTITUTION:Induction motors 9-10, 11-12 are respectively connected with variable voltage variable frequency inverters 7, 8, which are connected with a common filter capacitor. A rotating frequency calculator 17 selects the minimum value of the rotating speeds of the motors 9-12 at power drive time and the maximum value of the rotating speeds at regenerative time. An adder/ subtractor 19 adds a slip frequency fSP1 to a rotating frequency fr1 at the power drive time and subtracts at the regenerative time to output the output frequency fINV1 of the inverter 7. A phase difference setter 21 provides the prescribed phase difference in the fINV1 to output the output frequency fINV2 of the inverter 8.

Title: Sounding body controller
Inventor: KURITA HITOSHI
IPC: G10K9/12
Filed: 1988-08-23
Abstract: PURPOSE:To select user's favorite buzzer sound volume freely by operating a specific key among operation keys and varying the driving frequency of a sounding body. CONSTITUTION:The driving frequency of a ceramic buzzer can be varied by performing determined operation with operation keys, and consequently the sound volume of the ceramic buzzer is varied. For example, the buzzer sounds at a buzzer driving frequency f122, i.e. with maximum sound volume in a plug-in state, at a buzzer driving frequency f223, i.e. with intermediate sound volume when a buzzer key 19 is tapped once, at a buzzer driving frequency f322, i.e. with small sound volume when the buzzer key 19 is tapped twice. Further, when the buzzer key is tapped three times, the buzzer is turned off and does not sound. When the key is further tapped once more, the driving frequency returns to the buzzer driving frequency f1. Therefore, when the buzzer sound is too loud, the buzzer key 19 is tapped to reduce the sound volume and when the sound is not necessary, the sound is eliminated.

Title: Aluminum alloy clad material for brazing
Inventor: FUJIMOTO HIDEO
IPC: B23K1/19
Filed: 1989-08-11
Abstract: PURPOSE:To obtain the clad material having good brazability and corrosion resistance even by an 'nocolok(R)' brazing method by cladding an Al-Si series brazing material on one surface of an Al alloy core material contg. Mg at specific % or below and an alloy contg. Mg at specific % on the opposite surface. CONSTITUTION:The Al-Si series brazing material is clad on one surface of the Al alloy core material cong. <=2wt.% Mg as impurity and the Al alloy contg. 0.3 to 2.5wt.% Mg is clad on the opposite surface. Since the content of the Mg of the core material is low at the time of brazing, the brazability is not impaired. In addition, the Si in the brazing material diffuses into the core material and the Mg diffuses into the core material from the clad layer on the opposite surface at the time of heating for brazing. As a result, the MgSi is formed in the core material part and the strength after the brazing is improved. The concn. of the Mg is high and the concn. of the Si is low in the surface of the surface material and, therefore, the corrosion resistance is not degraded.

Accordingly, an optical output level where optical damage is generated is elevated remarkably.

Title: Electrostatic chuck
Inventor: KAYAMOTO TAKASHI
IPC: B23Q3/15
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic chuck which has high heat transfer efficiency and has excellent strength and durability. SOLUTION: Between a lower insulating layer 6 of an electrostatic chuck 5 and a base member 1, damper layer 2-4 are formed which are made of a composite material wherein the ratio of an addition agent to matrix metal varies in such a way that the coefficient of thermal expansion may become gradually higher from the lower insulating layer 6 side toward the base member 1 side in a specified range between the coefficient of thermal expansion of the lower insulating layer 6 and that of the base member 1. By forming the damper layers 2-4, the difference in coefficient of thermal expansion between the lower insulating layer 6 and the base member 1 is absorbed well and the appearance of thermal stress can be prevented and thereby the strength and the durability of the device are increased.  Especially, by brazing the electrostatic chuck 5 on the base member 1 or stacking the lower insulating layer 6, an electrode layer 7, and an upper insulating layer 8 on the base member 1 by flame coating or evaporation, the heat transfer efficiency between the layer is increased and thereby the cooling/heating efficiency of an object to be chucked such as a wafer is increased.

At the comparator 40, the difference between the early correlative value and the late correlative value is found and the differential value is compared with an internal parameter.  When the differential value is higher, moving width is secured wide and the speedy followup is performed.
