Filed: 1990-09-20
Abstract: PURPOSE:To prevent a time delay due to a limiter circuit from being caused by eliminating high-order m-bits other than a VSB of a signal line on the way of an arithmetic loop so as to obtain a limiter characteristic. CONSTITUTION:Figure shows a 1-bit D/A converter employing a sigma-delta modulator, and X(z),Y(z),E(z) are respectively an input signal, an output signal and z-conversion of a quantization error. The input digital signal X(z) is added to a feedback data at an adder 11. An output of the adder 11 is fed to a quantizer 12, the quantized output signal Y(z) by the quantizer 12 and an output of the adder 11 are subtracted by a subtractor 13. The output data of the subtractor 13 is digitally processed by a filter circuit 15 to be a feedback data. The filter circuit 15 consists of an integration device 16 and a 1-clock delay circuit 17. Then a limiter circuit 14 is inserted in an inter-stage of the filter circuit 15.

IPC: G11B11/10
Filed: 1993-10-05
Abstract: PURPOSE:To realize an optical disk of high reliability and very high density recording by erasing recording domains formed with a test pattern under such conditions for erasing as to form the widest magnetic domain. CONSTITUTION:In the figure, level Pr is the power for reproducing and Pas is the power for preheating. Pas is controlled to obtain a constant thermal interference quantity. Thereby, by combining an edge detecting method and a detecting method to independently detect front edges and rear edges, the edge shift amt. is controlled to a specified value or lower. Levels PW1 and PW2 are recording levels which are determined by the structure and material of the optical disk. After the recording region and read-level region in Tw are passed, the power level returns to the preheat level again. In the controlling method of test writing recording by this constitution, the recording film in the test pattern recording region shows no changes in magnetic characteristics by structural relaxation nor causes jitter or flucturation of edge shit. Thereby, an optical disk of high reliability and very high density recording can be realized.

Title: Semiconductor integrated circuit
Inventor: NAGASHIMA KENICHI
IPC: H01L21/8238
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce unwanted radiated electromagnetic waves by providing an electromagnetic wave reducing means, for flowing a current reverse to a current flowing a current path in parallel to current paths in a semiconductor element near which this reducing means is disposed. SOLUTION: When an input signal voltage turns from L to H or vice versa, a pMOS101 and nMOS102 turn on transiently simultaneously to flow a through- current 107, causing an electromagnetic wave 108 to be radiated. A current 110 also flows at the same intensity as that of the through-current 107 flowing in a semiconductor element and in the reverse direction thereto in a conductor 109 disposed near this element, so as to flow the current 110 in reverse to the current 107, resulting in radiation of electromagnetic wave 111 which has the same intensity as that of the current 107 but reverse in phase thereto. Hence the electromagnetic waves 108 and 111 are mutually cancelled as being radiated nearby. This reduces the electromagnetic waves radiated from a semiconductor integrated circuit.

Filed: 1992-09-18
Abstract: PURPOSE:To measure nucleic acid exactly without interference of light due to the luminescence of neighbouring sample holes by providing a plurality of sample holes and processing for light shield at least the side of each sample hole. CONSTITUTION:In a plate 2 for measurement, the light emitted from chemical luminescence reaction liquid S added by a luminescence substrate to enzyme- labeled nucleic acid indexed with alkali phosphatase is radiated in all directions at the light reception part 24 of a luminometer L placed in the vicinity of the opening of each sample hole 21. As coating agent C is spread on coloring paint and metal material, etc., for example, as light shielding processing on the side 22 and the bottom 23 of the sample 21 to be mirror surface, the light is reflected on the side 22 and the bottom 23 and proceeds to the opening of the sample hole 21 to be condensed at the reception part 24. Owing to the light shielding processing, the light from outside, especially from the neighbouring sample holes is shielded. By this, an exact measurement is possible.

Title: Starter
Inventor: GOTO SHIRO
IPC: F02N11/08
Filed: 1984-11-26
Abstract: PURPOSE:To improve the engagement between a pinion and a ring gear by slowly shifting the pinion to the ring gear side by a retention coil only, by releasing a switch means by a position detecting means until the pinion contacts with the ring gear after a plunger shifts. CONSTITUTION:When the captioned starter is not in operation, a movable contact-point 38 and a fixed contact-point 40 are in contact state, and a microswitch 25 is in closed state. Therefore, when a key switch 3 is closed, an attraction coil 4 and a retention coil 5 are excited to conduction, and a plunger collection body 8 is suction-accelerated. When a rod 39 is pressed into the cam groove 30 of the plunger collection body 8, the fixed contact-point 40 and the movable contact-point 38 are separated each other, and the conduction to the attraction coil 4 is cut-off, and the attraction force is reduced to the load of the turn spring 35 of the plunger collection body 8. Then, since the plunger collection body 8 is transferred by the attraction force of the retention coil 5 only, a pinion 12 can be shifted slowly to a ring gear 12 side through a lever 9.
