Title: Fault detecting method of knocking detector
Inventor: SUEMATSU TOSHIO
IPC: G01H17/00
Filed: 1982-02-04
Abstract: PURPOSE:To simplify the detection of faults of a knocking device, by controlling the knocking at an idling time and at the same time supplying a pseudo knocking signal to a knocking sensor to detect whether or not the ignition time point is delayed. CONSTITUTION:The level of the electric signal delivered from a knocking sensor 18 is compared with the level set previously. Then a pseudo knocking signal is supplied to the sensor 18 by striking the engine main body with a hammer while the knocking control is carried out to control an igniter 28. A timing light is used to detect whether or not the ignition time point is delayed. When the ignition is delayed, it means that the knocking control is carried out, i.e., the sensor 18 is normal. While it means that the sensors 18 is faulty if the ignition time has no delay.

Title: Motor controller
Inventor: ISHIMARU NOBUYUKI
IPC: H02P29/00
Filed: 1987-01-29
Abstract: PURPOSE:To obtain a servo motor having substantially no speed variation under a rotation control in a high speed range by extracting only a speed variation component, amplifying it, and applying it to a control loop. CONSTITUTION:A low pass filter (LPF) 13 is a filter made of a primary delay circuit having a transfer function of 30Hz of a folding point. Accordingly, the speed variation component having 30Hz or higher, which passes the LPF 13 is extremely small. An F/V converter 16 which inputs an electric command pulse (p) has the same primary delay circuit 20 as the LPF 12 at its output unit to stably hold the operation of a control system at the time of starting or stopping a servo motor 1. The output of a differential amplifier 17 is input to a high pass filter (HPF) 19 through a regulator 18 for regulating its phase. The HPF 19 removes a DC component contained in an input signal, extracts the speed variation component of the motor 1, amplifies it and outputs a phase- regulated signal. With this configuration, the motor 1 can be so controlled as not to substantially have a speed variation component.

If this incident direction is shifted from the prescribed direction, a control circuit 9 revolves the scanner 4 to change the direction of the beam 2. Thus the prescribed incident direction is secured for the beam 2.

Abstract: PURPOSE: To enhance the reliability of a current collector for a third rail and reduce the noise of the collector by supporting a current collecting shoe through an elastic member such as rubber or the like and reducing the impact vibration to be transmitted to the portions of the current collector.  
     CONSTITUTION: A rubber bush 11 is engaged with a bearing 9 provided at the central end of a supporting arm 3 and a current collecting shoe 2 is pivotally secured through a pin 10 to the bearing 9. The shoe 2 is elastically supported by an elastic member such as a vibration-proof rubber through supporting springs 12, 12 mounted at the arm 3. Impact vibration caused by the sliding contact between a third rail 1 and the shoe 2 is exactly shut off through the bush 11 and the springs 12, but is not transmitted to the arm 3. Therefore, the dynamic stresses occurred at the portions of the current collector are reduced to improve the reliability of the current collector and to lower the noise of the collector.

Title: High-frequency transformer
Inventor: TANABE KENZO
IPC: H05K1/16
Filed: 1986-01-30
Abstract: PURPOSE:To make a balancer hard to be influenced strongly by a conductive layer for electromagnetic field, even if it is arranged in the vicinity of a toroidal type coil, and yet to enable a thin type electromagnetic shielding, by closely coupling a multiple number of thin toroidal type coils having a rectangular cross section, using either a both-side or multilayer circuit substrate. CONSTITUTION:In the balancer, for instance, the primary winding consists of radial conductors 3A, 4A, 3C, 4C, 3E, 4E, etc. and thru-holes 5A, 6A, 5C, 6C, 5E, 6E, etc., having their electrodes 7A, 7B. The secondary winding consists of radial conductors 3B, 4B, 3D, 4D, 3F, etc. and thru-holes 5B, 5B, 5D, 6D, 5F, 6F, etc., having their electrodes 7C, 7D (central tap electrode), 7E. As mentioned above, this balance is of a close coupling of two pairs of toroidal type coils having a rectangular cross section. The main magnetic flux generated by a current running through the primary and secondary windings composes a closed magnetic route and is confined in the insulator 2 parallel with the substrate surface and composing the substrate. For this reason, even arranging a conductive layer for electromagnetic shield in the vicinity of the balancer can hardly influence the balancer strongly.
