Title: Production of information recording medium
Inventor: ENDOU ATSUSHI
IPC: G11B7/26
Filed: 1978-04-11
Abstract: PURPOSE:To improve resolution and signal S/N at the reproducing of an information recording medium using laser light by recording and forming undulation patterns having high accuracy on recording tracks of a substrate such as glass substrate or the like. CONSTITUTION:An Al layer 11 is formed to about film thickness 400 Angstrom  on a glass substrate 10. Ar laser light 14 for recording having been modulated according to video information is focused by a lens system onto the recording tracks of the layer 11 and is radiated to the substrate 10 while it is being rotated at a specified speed. The heat energy thereof causes the Al of the layer 11 to melt and evaporated, thus recording and forming the first undulation patterns 12 having the pits 12a, 12b corresponding to the information beforehand on the recording tracks. Next, with this layer 11 as a mask, the substrate 10 is ion-etched by a parallel electrode type plasma dry etching apparatus, whereby the second undulation patters 13 having pits 13a, 13b of depths 1200 to 1600 Angstrom corresponding to the patterns 12 are formed.

Title: Propeller damper device for outboard engine and the like
Inventor: OOTANI HIROAKI
IPC: B63H1/20
Filed: 1983-03-17
Abstract: PURPOSE:To make it possible to prevent vibration in the direction of thrust from being transmitted to the side of a casing, by disposing an auxiliary damper member between the inner cylinder or a boss section and a thrust receiving member. CONSTITUTION:An auxiliary damper member 28 is disposed between a supporting section 27 arrangement in an internal boss section 18B and a collar 23. Accordingly, if the thrust of a propeller 16 upon advancing is below a predetermined value, the propeller displaces forward with respect to a propeller shaft 14 by a distance M which is shorter than space distances W10, W20, to compress and deform the auxiliary damper member 28 between the supporting section 27 and the collar 23. The thrust of the propeller 16 is transmitted to the collar 23 through the auxiliary damper member 28, and therefore, vibration generated in the propeller 16 in the direction of the thrust is absorbed by the auxiliary damper member 28, thereby the transmission of the thrust to the side of a casing 11 is inhibited.

Title: Squelch circuit
Inventor: KAWAKAMI TOSHIKAZU
IPC: H04B1/10
Filed: 1984-03-06
Abstract: PURPOSE:To prevent malfunction of squelch depending on a received modulation signal by controlling a squelch gate from the result of comparison between an AGC voltage and a reference voltage. CONSTITUTION:A high frequency (RF) input 1 becomes an intermediate frequency (IF) signal by an RF amplifier 2, a local oscillation section 3 and a mixer 4 and amplified/detected by an IF amplifier detection section 5. The IF amplifier detection section 5 generates an AGC voltage, and a comparator circuit 11 for an AGC voltage and a reference voltage switches a squelch gate 6. Since the response speed of the AGC voltage is set sufficiently slower than the frequency response speed of a noise component and a voice component, the effect by the modulation frequency component is not given.

Title: Charge throttling device for diesel engine with supercharger
Inventor: IMAMORI TOSHIICHI
IPC: F02B3/06
Filed: 1985-03-04
Abstract: PURPOSE:To control the occurrence of pale smoke at low speed running by throttling a charge path at low speed running to generate internal exhaust gas recirculation, and providing a charge throttle valve to enlarge its opening at middle and high speed running downstream from a supercharger. CONSTITUTION:A charge connecting pipe 4 to connect a supercharger 2 with a charge cooler 5 is provided with a charge throttle valve 11. The charge throttle valve 11 is actuated only at the low speed running to throttle charge quantity and generate internal exhaust gas recirculation. Consequently, the internal exhaust gas recirculation causes exhaust gas including unburned gas to remain in a combustion chamber 17 and charge path 3, and then the above exhaust gas is burned during the following cycle. Thus the structure of Diesel engine becomes simple, and pale smoke occurring at the low speed running can be reduced.

Title: Discharge lamp lighting device
Inventor: NAGAKI TOSHIICHI
IPC: H05B41/02
Filed: 1993-03-04
Abstract: PURPOSE:To allow a stable operation and downsize a device by connecting a current regenerative arresting part to at least one of one terminal and the other terminal of the input winding of a transformer, and controlling a switching element and the current regenerative arresting part to apply a voltage to a discharge lamp. CONSTITUTION:When a switching arrester 21 is ON, a current is carried from a DC power source 1 through the input winding 311 of a transformer 3 and a current regenerative arresting part 91. The arresting part 91 is controlled into short-circuit or low impedance state, and a switching element 22 into OFF state. The output winding 313 of the transformer 3 is laid in impedance infinite state and in non-load state since a discharge lamp 5 which is a load is not broken down. Thus, exciting energy is stored in the transformer 3, and at the moment the element 21 is OFF, the exciting energy is applied to the discharge lamp 5, and the discharge lamp 5 is broken down. Thereafter, the impedance of the discharge lamp 5 is lowered, and the lighting is started. After the breakdown, the arresting parts 91, 92 are controlled into short-circuit or low impedance state, the elements 21, 22 are controlled to be alternately ON/OFF, and the discharge lamp 5 is stably lighted.

Inventor: KANG DONG-HEE
IPC: H04B14/06
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To isolate an error and to restore the original signal even when the error propagates by satisfying a specific relation among the input vector included in a window of an estimator, the number of middle point sub-filters, the constant that is optionally set and the operating characteristic expression of the i-th middle point sub-filter. SOLUTION: The SAM(subset average middle point) estimators 13 of the same constitution are used for an encoder 10 and a decoder 20 respectively, and the input vector included in a window is referred to as X with the number of middle point sub-filters, the constant that is previously set and the characteristic expression of the i-th middle point sub-filter referred to as P, (ai) and Fi (X) respectively. Thus, every estimator 13 can show its operating characteristic expression as SAM (X)=Σ<p> i1 ai Fi (X). It is possible to design a stable DPCM system which is used for the voice or image compression, to induce an operating expression for isolating an error and to minimize the estimation error by using the estimators 13.
