Task - To provide a worker safety management system that can adapt itself to changes in the conditions of the workers and the machines in a flexible manner and can finely manage the safety of the worker. Means to Achieve the Task - Worker safety is managed by using safety management information stored in an ID tag. The safety management information includes a work area code indicating a work area permitted to the corresponding worker and a danger avoiding capability code indicating a danger avoiding capability of the worker. The danger avoiding capability indicated by the danger avoiding capability code is determined from a worker skill of the corresponding worker that is evaluated in a standardized manner from past work experience of the corresponding worker and credits earned in a safety education program, and a specific degree of danger in the work area permitted to the worker.

Task - To provide a two-hand switch device that requires only a small load for each operation cycle. Means to Achieve the Task - The device comprises a left hand RF antenna placed in such a position as to enable a communication with the first RFID tag worn on the pre-determined position of the left hand of the worker only when the left hand of the worker is placed in a pre-determined left hand safe position, a right hand RF antenna placed in such a position as to enable a communication with the second RFID tag worn on the pre-determined position of the right hand of the worker only when the right hand of the worker is placed in a pre-determined right hand safe position and an output signal generating means for generating an output signal according to signals received by the left hand RF antenna and the right hand RF antenna.
摘要:
A substrate (101) is coated with an aqueous solution of boehmite (AlO(OH)) which is an aluminum hydroxide to form a coating film (102), and the property of the coating film (102) is modified into α-alumina, thereby joining the substrate (101) to a substrate (103).
摘要:
That portion of an n-type single-crystal Si layer 1 which corresponds to a pressure-sensitive region is etched to an SiO 2 layer 2 by using the SiO 2 layer 2 as an etching stopper layer. The SiO 2 layer 2 exposed by this etching is removed. The pressure-sensitive region of the n-type single-crystal Si layer 3 is etched by a predetermined amount to form a diaphragm 4. Thus, the SiO 2 layer 2 is removed from the diaphragm 4 and a diaphragm edge portion 6.

This invention includes a first electrode (10a, 10b, 10c, 30) and a second electrode (20a, 20b, 20c, 20d) which are arranged to face each other so as not to come into contact with each other and a gap between which changes in accordance with a change in an amount to be detected, and a signal processor 4 for calculating the amount to be detected on the basis of an electrostatic capacitance formed between the first and second electrodes. The first electrode has a portion (12a, 14a) and a portion (12b, 14b), areas of which that face the second electrode increases and decreases, respectively, upon a positioning error that occurs in a direction (x, y) parallel to the first electrode. These portions have the same area.
摘要:
A pressure switch comprising an external force transmission mechanism separating a cover and a housing, a first pressure chamber sectioned by the cover and the external force transmission mechanism, and a second pressure chamber sectioned by the housing and the external force transmission mechanism. The second pressure chamber is provided with a movable piece having first and second movable portions located oppositely, and one or more fixed contacts. The first and second movable portions are coupled through a leaf spring. The second movable portion is provided with a contact functioning as a movable contact. When the external force transmission mechanism applies an external force to the first movable portion, the first movable portion is displaced, the second movable portion is reversed at the action point of the first movable portion, and thus the movable contact comes into contact with the fixed contact.
