Title: Crosstalk detecting device for recorded information reproducing device
Inventor: KANAMARU HITOSHI
IPC: G11B7/005
Filed: 1981-05-09
Abstract: PURPOSE:To detect the direction of the occurrence of crosstalk on a basis of the direction of oscillation of a pickup spot for detection of crosstalk, by oscillating minutely the pickup spot in a direction approximately orthogonal to the track at a period of about 30Hz. CONSTITUTION:Only the horizontal synchronizing signal period of a detection signal is gated by a gate circuit 3, and beat components to luminance signals of adjacent tracks included in the signal are extracted by a BPF and are subjected to envelope detection. This output B has the peak held at every horizontal period in a holding circuit 6. An output C of the circuit 6 is subjected to synchronous detection to detect a crosstalk quantity. Meanwhile, DC cut components of the peak holding output C and a tracking mirror driving signal (pickup spot oscillating signal) are multiplied in a synchronous detector 7 to detect the direction of the occurrence of crosstalk.

Title: Dissolving method for oxygen in water
Inventor: MIURA MITSUGI
IPC: B01F5/04
Filed: 1978-06-10
Abstract: PURPOSE:To considerably enhance the efficiency of dissolving oxygen in water by passing water through the inside of a porous pipe and by feeding pressurized air from the outside through the pores to mix fine air bubbles into the water. CONSTITUTION:Air bubbles fed through the pores of porous pipe 2 by water flowing through the inside of pipe 2 at such a high speed as 1-3 m/S are cut short without being made long columnar by the shearing force of the water. The bubbles rapid ly move on the water stream, and the adjacent bubbles are prevented from adhering to each other. Thus, much finer air bubbles than those of a conventional method are obtd. Accordingly, vapor-liquid contact area is considerably increased, resulting in enhanced efficiency of dissolving oxygen in water.

Title: Lsi circuit for interface
Inventor: WATANABE YASUHISA
IPC: G06F3/00
Filed: 1990-03-19
Abstract: PURPOSE:To easily form plural compact interfaces with high performance by setting a delay line into an interface LSI circuit for production of plural skew compensated strobe signals and providing the selection circuits. CONSTITUTION:Two types of interfaces are prepared and the interface type selection signals 16 and 17 are supplied from outside. The signal 16 is set at logic 1 in a type 1 and a strobe signal 11 is received by a receiver circuit 1. The output 12 of the circuit 1 is delayed via a delay line 2. The output 13 that secured the skew compensating time needed for the interface of type 1 is outputted to the output 15 by a selection circuit 3, the data bus signal received by a receiver circuit 4 is fetched by a data register 5. At the same time, the signal 17 is set at logic 1 with use of the interface of type 2 and the output 14 of the line 2 that secured the skew compensating time needed for the interface of type 2 is outputted to the output 15 by the circuit 3. Thus a sampling signal of the register 5 is obtained.

Title: Masked coating
Inventor: FURUYA HIDETOSHI
IPC: B05D1/32
Filed: 1987-03-26
Abstract: PURPOSE:To form a coating with a sharp parting line by applying pressure to a space formed between a mask and a molding, performing coating and preventing paint from penetrating between the molding and the mask. CONSTITUTION:The uncoated part 4 of a molding 2 mounted on a cradle 11 is covered with a mask 5, and a valve 14 is opened to feed compressed air from a cylinder 16 and thereby apply pressure to a space 12. The blow coating of the molding with paint 7 is applied from the external surface of the mask 5. At that time, if there is a clearance 8 between a member 5b at the tip of the mask 5 and the molding 2, air released through the clearance 8 from the space 12 and an air stream containing the paint 7 blown at the tip of the mask 5 are canceled against each other. Therefore, the paint 7 is not allowed to penetrate into the clearance 8, and subsequently, no disturbance exists in the parting line 9, thus making a superior-looking coating 3 available.

Title: Device for controlling optical signal and method for controlling optical signal in optical waveguide
Inventor: RICHIYAADO EICHI PANTERU
IPC: G02F1/35
Filed: 1993-03-29
Abstract: PURPOSE: To provide a coupler of optical mode equipped with an optical waveguide to which erbium doping is performed. CONSTITUTION: The optical signal of signal wavelength is propagated in the 1st and 2nd spatial propagation modes of a waveguide 302. The optical signal to be propagated through the waveguide 302 has a beat length. A coupler 300 is provided with pump sources 320 and 330 for the perturbing optical signal of perturbation wavelength to be propagated through the waveguide 302 in the 1st spatial propagation mode. Inside the wavelength 302, the perturbing signal has strength distribution enough for perturbing the effective refraction factor of the waveguide 302 in the 1st spatial propagation mode according to the optical Kerr effect. This perturbation changes differential phase delay in optical signals to be propagated in the 1st and 2nd spatial propagation modes.  The change in the differential phase delay is detected as a change in the strength distribution between two robes of optical strength distribution pattern of an output signal. The perturbing optical signal is selectively enabled/disabled and selectively changes the strength distribution of two robes of the optical strength distribution pattern.

IPC: H01F1/34
Filed: 1993-03-05
Abstract: PURPOSE:To obtain a Mn-Zn based ferrite high in permeability and excellent in temp. characteristics by restricting the composition of the Mn-Zn based ferrite and specifying initial permeability and the rate of change thereof.

In the ferrite, it is the reason why restricting the component that the initial permeability nearly at room temp. can not attain >=8000 since the secondary peak (Ts) becomes minus side due to the temp. characteristics of the initial permeability when Fe2O3 is >=53mol.% and when Fe2O3 is <=52.5mol.%, the secondary peak is in high temp. side and the initial permeability mu in the minus side can not attain >=8000.
