Title: Optical disk device
Inventor: YAMAGUCHI HIROYUKI
IPC: G11B19/02
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To start up an optical disk device stably and in a short time by providing an address part detecting means to detect the address part for discriminating a region on a disk and a timer for measuring time intervals of an output signal of the address section detecting means, and then discriminating the kind of media based on the measured value of the timer. SOLUTION: A microcomputer 14 starts follow-up operation to a track. On this condition, a differential circuit 11 outputs a regeneration difference signal. A detecting circuit 13 of difference address part detects the envelope of the regeneration difference signal, detects the address part from the polarity change, and then outputs pulses of prescribed width to the microcomputer 14 every time an optical beam passes through the address part. The microcomputer 14 measures the cycle of output of this detecting circuit 13 of difference address part by a built-in timer, and then discriminates whether a disk 1 is a disk of a small capacity or a large capacity. Thereby, the microcomputer 14 is set so as to make setting of various elements for constituting device optimum.

Title: Inverter circuit
Inventor: YOSHIDA HIROAKI
IPC: H05B41/24
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient small-sized inverter circuit, which does not produce much noise at a low cost, without requiring auxiliary boosting means for a piezoelectric transformer. SOLUTION: Switching elements Q1 and Q2 are driven with control signals S1 and S2 from a control circuit 5 and switch the direct current from an input terminal 10 upon which a DC voltage Vin is applied. A capacitor C1 and a choke coil L1 constitute a first-stage resonance circuit section and the inter- electrode capacity C2 between a choke coil L2 and a piezoelectric transformer T1 constitute a next-stage resonance circuit section. The transformer T1 is driven at the resonance frequency generated from the two stages of serial resonance circuits. A resistor R1 is installed for detecting a tube current IL flowing to a cold cathode tube 4 and controls the switching frequencies of the switching elements Q1 and Q2, by applying negative feedback to the control circuit 50.  Consequently, the drive voltage of the transformer T1 is changed, and the outputted power is controlled correspondingly to the changed drive voltage.

Abstract: PROBLEM TO BE SOLVED: To withstand chemical and mechanical polishing by forming a central region on the surface of an insulation film buried into a wide trench so that it projects when forming a plurality of trenches and making nearly flat the surface of the insulation film that is left in the trench when selectively eliminat ing the insulation film on a protection film. SOLUTION: A plurality of trenches 6 are formed on a semiconductor substrate 1. Some have wide width, while others have narrow width. Also, some have a dense pattern, while others have a coarse pattern. More specifically, in a region A, a trench 6 with a narrow opening width and a narrow active region exist densely. In a region B, the trench 6 with a wide opening width and a narrow isolated active region exists. Therefore, a protrusion is formed at the central region of the trench width 6 with a wide opening width as seen in the region B, the protruding height of an insulation film 8 buried into the trench 6 is made small and uniform, and the surface is formed nearly flatly.  As a result, the surface of the insulation film being buried into the trench 6 is also formed in a protruding shape, thus preventing a protection film from being lost and the isolated active region from being cracked even if the insulation film 8 is excessively polished in a post process.
