Title: Pentagonal dach-prism
Inventor: MOMIYAMA KIKUO
IPC: G03B13/26
Filed: 1980-09-10
Abstract: PURPOSE:To facilitate and to reduce cost by combining a simple triangular prism as the 1st prism and another simple triangular prism as the 2nd prism in one body. CONSTITUTION:A pentagonal Dach-prism 4 is cut with a plane including vertexes 41, 45, 46, and 44 and separated into an upper and a lower part as the 1st prism and 2nd prism respectively. The vertexes 41', 44', 45', and 46' of the 1st prism 5 are the same as the vertexes 41, 44, 45, and 46 of the 2nd prism 6 before cutting. Here, the 1st prism 5 and 2nd prism 6 are manufactured separately and independently and those two prisms are combined to obtain one pentagonal Dach-prism. The 1st prism 5 and 2nd prism 6 are both manufactured easily by cutting a triangular prism properly. Thus, the manufacture is simplified and the cost is reduced.

Abstract: PURPOSE:To enable a capacitor element to be easily formed without imposing any load on processes and circuit design by a method wherein a thin insulating film of high quality is formed on an electrode wiring. CONSTITUTION:At least two insulating films 2 and 3 are formed on a first electrode wiring layer 4 to serve as interlayer insulating films. The lower insulating film 2 is left unremoved making use of a difference between the films 2 and 3 in etching resistance, a second electrode wiring is formed thereon, a part of the second electrode wiring is made to serve as an electrode 7a, and thus a capacitor element 8 is formed.

Filed: 1993-04-28
Abstract: PURPOSE:To reduce the cost and to enhance the energy efficiency in a turbocharger controller which uses an electric rotating machine fitted to a rotation shaft of a turbocharger for operation as a generator or a motor, as required. CONSTITUTION:A plurality of speed increasing mechanisms that use gears 15(16) are mounted on the rotating shaft of an engine 1 and a.c. machines 17, 18 are respectively connected thereto.

IPC: G01B7/16
Filed: 1979-09-28
Abstract: PURPOSE: To realize a high-accuracy measurement of load, by securing a parallel insertion of the reference resistor to one side of the bridge circuit forming the distortion gauge and thus giving a correction to the measurement through a comparison between the reference level of the output voltage caused by the above reference resistor and the sampling value right before measurement.  
     CONSTITUTION: The voltage of the power source 3 is applied between the terminals (a) and (b) of the bridge circuit 2 formed with the distortion gauge 1, and thus the output voltage between the terminals (c) and (d) is amplified 4. Then the reference resistor 5 is inserted between the transmission lines l a  and l c  of the bridge circuit via the relay contact 6a. And then the output voltage of the amplifier 4 when the contact 6a is closed after the installation and control of the detector is stored in the momory 10 in the form of the reference value E st  and by the control circuit 7. After the start of the detector, an intermittent closure is given to the contact 6a when the output voltage of the amplifier 4 is lower than the prescribed level, and thus the output voltage of the amplifier 4 is sampled 12. Then the compensation factor is calculated 13 from the sampling value and the reference value. In such way, the output voltage E x  of the amplifier can be corrected according to the sampling value right before the detection and when the load is detected.

Title: Motor rotational frequency detector
Inventor: MASUDA HIROYUKI
IPC: H02P27/06
Filed: 1989-05-22
Abstract: PURPOSE:To miniaturize a transformer through reducing the effect of an external magnetic field by constituting an apparatus in the manner of limiting the input voltage from an inverter on the primary side of said transformer. CONSTITUTION:A resistor 2 limits electric current flowing through a voltage- limiting circuit 50 during the operation of an inverter 21. As a result, a voltage across both ends of said voltage-limiting circuit 50 is limited by diodes 4-7 and the magnitude of Zener voltage of a Zener diode 8. In this case, the imbalance between positive and negative voltages is the difference between ON-state voltages of said diodes 4-7. However, when the diodes 4-7 respectively housed in the same package are used, they are diodes in the same lot and the difference between said ON-state voltages becomes smaller. In this manner, as the voltage is limited on the primary side of a transformer 9, the burden on the secondary side of said transformer 9 is only a comparator 10. Thus, the title apparatus can be operated with a little burden and a small number of turns. Accordingly, it is possible to reduce the effect of an external magnetic field and to miniaturize said transformer 9.
