Title: Engine ignition timing control device
Inventor: HARADA OSAMU
IPC: G01L23/22
Filed: 1985-04-24
Abstract: PURPOSE:To surely determines whether knocking occurs or not to prevent pre-ignition, by compensating a constant for calculating a reference value which determines the occurrence of knocking, with the use of the output of detection for the voltage of a battery, and by holding the reference value for determination at a fixed value. CONSTITUTION:When the rotational speed of an engine falls in a specific speed range and the voltage of a battery drops in such a condition that its electrical load is turned on, noise generated from an alternator 50 is superposed on the output of detection by a knock sensor 22, and therefore, the value of background becomes excessively large. Accordingly, a process in which a constant K is turned into 0.8XK is carried out to hold a reference for determination at a fixed value which is compared with peak values. Accordingly, even if the value of background becomes excessively large, it is possible to surely determine whether knocking occurs or not, thereby it is possible to prevent the engine from falling into its pre-ignition condition.

Abstract: PURPOSE: To increase the separation of paper from fixing roll, by selecting the surface effective hardness of the elastic body layer so as to be fixing roll ≤ pressurizing roll.  
     CONSTITUTION: Rubber layers of the same 0.75mm thickness are provided on a fixing roll and a pressurizing roll, and the heat response to the metal roll and rubber layer roll is improved, while maintaining the equivalent contact width, and increasing the effective hardness of the pressurizing roll by setting the hardness of pressurizing roll higher, i.e. JISA 45° for the pressurizing roll as compared with JISA 25° for the fixing roll, an excellent separation is obtained. Thus, by selecting the relation between the fixing roll and pressurizing roll to establish the relation of effective hardness of fixing roll ≤ effective hardness of pressurizing roll, the pressurizing roll bites into the fixing roll, so that the separation of paper may be enhanced.

Thus, the power consumption of the NTL circuit is reduced without disturbing its high speed operation.

Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To avoid local generation of eddy current and generation of magnetic saturation, by dispersing magnetic flux distributed on the winding start part and the winding end part of a silicon steel plate, along the longitudinal direction of the silicon steel plate. SOLUTION: End edges of the winding start part 2 and the winding end part 3 of a silicon steel plate 1 are obliquely cut so as to slant to the longitudinal direction of the silicon steel plate 1. It is considered that magnetic flux concentrates along end edges of the winding start part 2 and a winding end part 3 of the silicon steel plate 1, so that the shape wherein the end edges are slanted is used, and the magnetic flux is dispersed on the slant direction, i.e., along the longitudinal direction of the silicon steel plate 1. Thereby generation of eddy current is reduced, and magnetic flux density can be reduced.

Title: Black level correcting device
Inventor: KAWASAKI YOSHIO
IPC: H04N5/57
Filed: 1985-04-26
Abstract: PURPOSE:To eliminate the fluctuation of a black level even when the APL of a transmitting television signal is low by providing a diode in series with a black level correcting resistor which takes out a black level correcting voltage. CONSTITUTION:When the APL of a transmitting television signal is decreased, potential at a point A rises and the voltage of a terminal 2 on an IC5 in a video signal processing circuit rises through a contrasting volume 2 and contrast is controlled to be strong. However, at such a time, the voltage of a terminal 23 is not changed because the transmission of the rising share f the voltage rise at the point A through a diode 6 is interrupted and a luminance level is not changed. Namely, the black level is not changed. Thus, by providing the diode 6 in series with the existing black level correcting resistor 3, a stable black level reproducing operation is realized even when the APL of the transmitting television signal is decreased.

Title: Controlling method for operation of multiple core drill
IPC: B28D1/14
Filed: 1992-03-13
Abstract: PURPOSE:To raise the efficiency of operation by a method in which the operation of a multiple core drill for core-drawing operations is controlled according to the condition of wall on the drilling position. CONSTITUTION:A rotary plate-fixing base 1 to be fixed by an anchor bolt 2 to the drill center and attraction metal plate 15 to support the reaction of the core drill on the periphery of the base 1 are attached to the concrete wall on the drilling position. A core-drawing operation is made by using a multiple- type core drill in which a core drill is provided to the tip of a slewing frame 6 to be fixed to the metal plate 15 on a setting position and supported rotatably by the support shaft of the base 1, where a rotary bit 10 is pressed on the concrete wall for drilling by a preset pressing force. When an excessive load beyond a set value is applied to the bit 10 during the core-drawing operation, the times of the excessive load are counted and reach a set times, the bit 10 is separated from the concrete wall to restore it to a waiting position for the next drilling operation. The core drill can thus be protected and the core- drawing operation can be automatically made.

IPC: G03B21/14
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve light condensing efficiency without making the size of a reflector large by constituting the reflector of a first concave reflection mirror, a second concave reflection mirror reflecting a light component which does not irradiate the first reflection mirror toward a specified position in the vicinity of an optical axis, and a third convex reflection mirror provided on the specified position and reflecting light reflected by the second mirror ahead of the optical axis. SOLUTION: One part of a luminous flux emitted from an emitter 4 and going behind and above the optical axis X1 is reflected by the parabolic-surface-shape first concave mirror 1 as a luminous flux in parallel with the optical axis X1. A luminous flux going above and obliquely ahead of the optical axis X1 is reflected by the elliptic- surface-shape second concave mirror 2 toward the parabolic-surface-shape third convex mirror 3 disposed on the optical axis X1, and reflected by the mirror 3 in the vicinity of the optical axis X1 as the luminous flux in parallel with the optical axis X1. Thus, the luminous flux emitted from the emitter 4 can be efficiently reflected ahead of the optical axis X1 without causing omission in the optical axis even in the vicinity of the optical axis X1.
