Title: Position detector
Inventor: KANDA SHIGETO
IPC: G11B7/085
Filed: 1988-04-07
Abstract: PURPOSE:To enable movement of a light head eliminating any adverse effect otherwise caused on a tracking servo, by selecting an output by a selection means according to an output of a phase detecting means while an output of a variable voltage generating means is changed. CONSTITUTION:A multiplexer 1 selects a phase signal corresponding to the number at which it is equivalent to the contents of a first counter 5 from among those of first to fourth phases to obtain an output VS. An output C1 of a voltage comparator 2 is connected to a DEC terminal of counters 5 and 4 and the counters 5 and 4 are subjected to a decremental counting at a rising edge of the output C1. Likewise, an circuit C2 of a voltage comparator 3 is also connected to the counters 5 and 4, which 5 and 4 are subjected to an incremental counting at a rising edge of the output C2. Then, the contents of the counter 4 are converted with a D/A converter 6 into a voltage to be an output VD, which is added up to an output VS with an adder 7 to enhance a phase detection range of monotonous increase equivalently. This upgrades a resistance to vibration from outside in a position control to such an extent that no uselessly large acceleration is caused even when the phase is shifted thereby eliminating adverse effect on a tracking servo.

Filed: 1985-04-19
Abstract: PURPOSE:To eliminate a hazardous condition due to prompt steering by configurating a device in such a way that rear wheels are controlled by a regular mode when a car is running normally, but when the car is running on a road, sliding resistance of which is low, the mode is automatically switched to a special one which allows a steering angle of the rear wheel to be controlled. CONSTITUTION:Both a speed signal (a) from a speed sensor 12 and a front wheel steering angle signal (b) from a front wheel steering angle sensor 13 are inputted into a control circuit 11, and a rear wheel steering angle is computed based on the steering angle ratio between a front wheel and a rear wheel which are set in advance against the specified speed, and an actuator 7 is controlled allowing the rear wheel 10 to be steered. In this case, when a car is in a normal running, a reverse phase steering is effected between the front and rear wheels in a low speed range, but a same phase steering is effected at the moment when a steering angle ratio (k) between the front and rear wheels becomes zero as speed is in creased. And a regular mode 1 is effected in a high speed range where (k) is allowed to come gradually close to 1. In addition, when a road of low coefficient mu is detected by a road surface condition sensor (not shown), a mode switch is allowed to be changed to a special mode 2 where change characteristics of a steering angle ratio (k) between the front and rear wheels is switched from the regular mode 1 to a zone, in which the reverse phase steering angle between the front and rear wheels is made zero or minimum.

Title: Ghost eliminating device
Inventor: MURATA TOSHINORI
IPC: H04N5/21
Filed: 1982-05-21
Abstract: PURPOSE:To improve eliminating characteristics of the high frequency component of the ghost and to eliminate not only the luminance ghost but the color ghost, by using a device containing a transversal filter to use a burst signal as the reference signal. CONSTITUTION:A transversal filter is constituted with delay elements 21-26 connected to a video signal input terminal 1, tap amplifiers 31-36, switches 41- 46 and an adder 5. The delay time of the elements 21-26 is set 3 times as much as the frequency of a burst signal (3.58MHz). The output of the adder 5 is applied to a burst signal detecting circuit 7 to detect the burst part of a vertical flyback time. This burst part is applied to a 3.58MHz continuous wave generating circuit 8 and synchronous wave detecting circuits 11-13. While the signals given from the circuit 8 are converted into signals of different phases by 120 deg. phase shifters 9 and 10 and applied to the circuits 11-13. The outputs of the circuits 11-13 are written to a tap gain memory 18 via a shift register 16. Then each tap of the filter is controlled with the burst signal used as the reference signal. Thus the eliminating characteristics can be improved for the high frequency component of the ghost.

Title: Resin hose having excellent resistance to pressure deformability
Inventor: TATEYAMA MASARU
IPC: F16L11/11
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To attain a hose which is flexible and reduced in elongation when being pressurized by providing a bellows shape at least in a part of the hose, and making the section of an angled part of the bellows shape oval or elliptical. SOLUTION: A hose has a bellows structure at least partially, and the section of an angled part of the bellows part is oval or elliptical. The smaller the angled part height ratio (h1/h2) of the angled part height h1 in the minor axis direction to the angled part height h2 in the major axis direction is, the smaller the elongation of the hose while being pressurized is, which is effective for improvement in pressure and deformation tightness. Preferably the angled part height ratio is 0.75 or less. When it is too small, the flexibility is easily damaged. Accordingly, preferably it is at least 0.1 to more. the change amount in the direction of an elliptical axis of the adjacent angled parts is 3 degrees, preferably 15 degrees. Thus, excellent flexibility and resistance to pressure deformability can both be provided together.
