Title: Controller
Inventor: OGAWA KENJI
IPC: G05D3/12
Filed: 1988-12-10
Abstract: PURPOSE:To execute other control operation without time delay by detecting the completion of feedback control and leading a stopping signal out of a stopping signal generating means. CONSTITUTION:The completion of the feedback control concerning the output level of a control load is detected by counting the output of a level discriminating means 14 in a counting means 15 synchronously with a clock signal.

Title: Optical recorder
Inventor: YONEZAWA SEIJI
IPC: G11B7/09
Filed: 1989-12-04
Abstract: PURPOSE: To record and to reproduce data while precisely tracking the center of a track by a light spot by compensating for the tracking signal based on the error signals detected from reflected light beams when a track deviation compensation mark is irradiated with the light spot. CONSTITUTION: The light spot by a tracking actuator 26 is scanned in the slanted direction across the track. One of the divided lines of the reflected light beams from a recording medium is received by a quadripartite detector 17 which is arranged in approximately parallel to the track. The output signals of the detector 17 are arithmetically processed so that the tracking offset, which is caused by the movement of the luminous flux on the detector 17 due to the movement of the actuator 26, is reduced. Moreover, the tracking signals are compensated for based on the error signals detected from the reflected light of the track deviation compensation mark. Thus, the light spot precisely tracks the center of the track and a data recording and a reproducing are conducted.

Title: Optical disk recording device
Inventor: KATSURAMOTO SHINJI
IPC: G11B7/26
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To record signals by using an ultraviolet laser beam without deterioration of the signal quality by removing scattering particles generated from an optical disk at the time of forming signal grooves on the optical disk by using a blow-off nozzle. SOLUTION: A gas pressurized by a gas pressure source 41 is led to a valve 43 through a conduit tube 42. The valve regulates a flow rate of the gas. The blow-off strength of the gas onto the optical disk 8 is thus controlled. The flow rate regulated gas is led to a blow-off nozzle 45 through a conduit tube 44, and is blown off from the tip of the nozzle 45 onto the position where a pit is to be formed on the disk 8. The nozzle 45 is arranged so that it always maintains a fixed positional relationship to an objective 6 and the optical disk 8 and also the gas blown out of the nozzle flows approximately in a fixed direction. Thus, articles scattered from the optical disk 8 associated with pit forming can be removed.

IPC: H03F1/52
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To obtain a high-frequency device which is constituted to prevent the breakage of a high-frequency amplifier. SOLUTION: When comparison amplifiers 17 and 18 discriminate electric power as reflected power 0 through the adjustment of a matching variable capacitor 7 and a tuning variable capacitor 8, the amplifiers 17 and 18 send matching signals to a comparison amplifier 20.

Title: Knocking detector for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02P5/15
Filed: 1989-12-05
Abstract: PURPOSE:To evade the acceleration of knocking due to a misjudgement of knocking occurrence in acceleration or a misdecision on no knocking in deceleration by setting a background level by using the weight set according to the extent of acceleration or deceleration. CONSTITUTION:A background level arithmetic means calculates the weighted mean of the detection signal from a knocking sensor at all times to set the background level as a reference for extracting a knocking component. A knocking discriminating means discriminates knocking with the detection signal of the knocking sensor according to the calculated background level. An acceleration/deceleration extent detecting means detects the extent of acceleration or deceleration of the engine and a weighted mean weight setting means sets the weight of weighted mean arithmetic by a background level arithmetic means according to the detected extent of acceleration or deceleration. Consequently, when the acceleration/deceleration extent is large, the weight of the latest detected value is increased to set a request value with good response while making the background level follow up variation in the load.
