Title: Valve timing variable tappet
Inventor: KATSURADA SHIRO
IPC: F01L9/14
Filed: 1985-01-22
Abstract: PURPOSE:To change valve timing by means of a simple and cheap constitution by making only an outer cylinder slide relative to a stantionary inner cylinder at an early period of cam-lift at the time for changing timing, at with a valve on the low pressure chamber side closed and a valve on the high pressure chamber side opened. CONSTITUTION:When the timing of a hydraulic tappet is to be changed, the first valve 18 is closed, while the second valve 31 is opened. When the bottom wall 8 of an outer cylinder 6 is pushed up by a cam 3 under this condition, a high pressure chamber 15 is compressed in a space between an inner cylinder 9 and the outer cylinder 6, and the oil in the high pressure cylinder chamber 15 is discharged via a high pressure chamber oil escaping hole 32 and the second valve 31. Then, at the early period of cam-lift, since the lift is absorbed by a sliding motion between outer and inner cylinders, the valve timing is changed. In other words, only the outer cylinder 6 moves up by a certain amount relative to the inner cylinder 9 that is in a stationary condition. As a result, a push rod 4 maintains a stationary condition. Therefore, the opening timings of air- inlet and discharge valves are delayed. With this contrivance, the valve timing can be changed by means of a simple and cheap constitution.

Title: Method for recording information signal
Inventor: TSUDA YOICHIRO
IPC: G11B7/30
Filed: 1991-01-31
Abstract: PURPOSE:To perform high-quality information recording by retrieving in advance a dropout area in the recording area of a recording medium and recording information signals in a normal area having no scratch nor contamination except the dropout area. CONSTITUTION:The address of an optical disk used for recording is managed in such a way by means of a recording/reproduction controller 21 that the addresses of the scratched or contaminated areas of the optical disk having addresses of recording areas are retrieved in advance and such areas are not used for recording when video and audio signals are recorded. Therefore, a retrieving mode is set before starting the recording of information signals and, when a dropout occurs in read signals obtained as a result of playing prescribed reference signals, such as sine waves, digital pulses having a 50% duty, etc., after the reference signals are recorded in all recording area of the optical disk, the address of the dropout area is stored. Then, in the recording mode, the information signals are recorded by detecting the address of the recording area so that the signals can be recorded in normal areas other than the dropout area.

Title: Method of spark erosion
Inventor: MITSUMIZU TAKAMURA
IPC: B23H1/10
Filed: 1980-02-01
Abstract: PURPOSE:To heighten the accuracy of spark erosion, by rotating an electrode while supplying a pressurized spark erosion liquid in between the electrode and a workpiece through a spark erosion liquid passage provided on the side or bottom of the electrode. CONSTITUTION:An electrode 4 for spark erosion is fitted in a rotary drive shaft 2 by a chuck 3 on the tip of the shaft 2 so that the axes of the electrode 4 and the shaft 2 are coincident with each other. A pressurized spark erosion liquid from a pipe 8 is introduced into a passage 6 through an input end 6f and a passage 9 and ejected from ports 6a-6e. Chips made between a workpiece 5 and the electrode 4 are forcedly removed out of the discharge gap with high efficiency. Since stress due to a tensil force which the electrode 4 receives in such a direction as to narrow the discharge gap is dispersed uniformly, the electrode 4 is efficiently prevented from being deformed and accurate spark erosion is enabled. Since the electrode 4 is rotated, the strain of the electrode itself is apparently corrected to prevent the accuracy of spark erosion from falling because the consumption of the electrode 4 would be nonuniform.

Title: Emphasis and de-emphasis circuit of chroma signal
Inventor: TAKASE OSAMU
IPC: G11B20/02
Filed: 1983-01-28
Abstract: PURPOSE:To use a combined emphasis and de-emphasis circuit by using feedback technology by constituting the emphasis and the de-emphasis circuit with a trap circuit comprising a variable impedance element where diodes are connected in parallel with an opposite polarity, L and C. CONSTITUTION:A voltage of Ae1 is produced to a VCV (voltage controlled voltage source) 3 by a signal voltage source 1. A chroma signal where a chroma subcarrier frequency component is suppressed and only a side band component remains and the maximum level is limited is produced to an input of a buffer circuit 6 having a resistor R4 and a nonlinear circuit 5 as a load to the voltage Ae1. The signal like this is extracted through the buffer circuit 6 and added to an original signal at an adder circuit 7. Thus, a signal obtained at an output terminal 8 is a signal in which the side band is emphasized and the degree of emphasis is increased more as the level of the side band of the original signal is small. Thus, the S/N cf a chroma signal having a small side band level is improved by passing the signal subjected to emphasis processing through a de- emphasis circuit having the inverse characteristic in the reproducing circuit.
