Title: Inspecting device for optical disk
Inventor: TSURU TETSUO
IPC: G11B7/00
Filed: 1985-10-08
Abstract: PURPOSE:To allow an optical disk to collect information on defects of itself by providing a means which detects defects regarding the unrecorded position of the optical disk based on the level of the output signal of an optical head and stores position information related to the detected defects, which includes defect information, in a memory. CONSTITUTION:The defect information is read from the memory 38, and defects which are provisionally stored in the memory and then detected are classified by their size. Since the optical disk device has an error correction function, an error due to a fine defect can be correctable. Only the defects at a size developing an error which cannot be corrected by said error correction function are selected, and their number is counted by a sector. The disk is decided to be usable or not by the sector from the number of defects, and the optical disk is decided to be usable or not from said decision. Thus the defects of the optical disk are inspected, and the defect information including at least position information is obtained to analyze the occurrence cause of the defects, whereby said analysis can be reflected to the control of the optical disk process.

Abstract: PROBLEM TO BE SOLVED: To improve a driving frequency by obtaining a sufficient shift of a diaphragm to discharge ink even when a gap defined by the diaphragm and an individual counter electrode is narrowed so as to lower a driving voltage and driving the diaphragm without being in touch with the individual counter electrode. SOLUTION: When a voltage is not impressed, an individual counter electrode 2 and a diaphragm 11 are in a state (A). When a driving voltage is impressed between the individual counter electrode 2 and the diaphragm 11, the diaphragm 11 is shifted by a static electricity and a thick part 11a of the diaphragm 11 comes in touch with an upper face 7 of a step 5 as shown in (B). The thick part 11a of the diaphragm 11 faces the counter electrode 2 via a gap, i.e., a height L of the step. The thick part 11a of the diaphragm and the counter electrode 2 are equivalently in a state (C). In driving the diaphragm electrostatically, the diaphragm is instable to reach 1/3 the gap and collides with the counter electrode 2. For avoiding the collision, the diaphragm 11 is displaced in a range higher than 2/3 the height L of the step.

Title: Memory back-up device for microcomputer
Inventor: MORI YASUHIRO
IPC: G06F1/00
Filed: 1987-09-08
Abstract: PURPOSE:To surely back up a memory when a power supply is cut off by using the signal of a secondary voltage monitor circuit or a primary side open state detecting circuit to perform the back-up processing of the memory. CONSTITUTION:A primary side open state detecting circuit Tr transmits a signal in response to the open state of a switch means S1 which secures connection between the primary side of a switching regulator and a power supply. While a secondary side voltage monitor circuit 5 transmits a signal when the secondary side voltage of the regulator 3 drops less than a prescribed level. Then a memory 2 is backed up by the signal of the circuit 5 or the circuit Tr. Thus the sure back-up processing is secured for the memory 2 since the sufficient time margin is secured before the secondary side voltage drops less than the level of the action assuring voltage of a logic circuit. As a result, storage contents of the memory 2 can be protected.
