Title: Radiation temperature measurement method and radiation thermometer used for it
Inventor: ONO JIRO
IPC: G01J5/00
Filed: 1990-11-29
Abstract: PURPOSE:To enable temperature to be measured in that influence of radiation rate is reduced for wide measurement targets by using an output of a sensing element with a sensitivity for two or more measurement wavelength bands and then performing calculation from an interpolation table for correcting signal by a preselected standard sample. CONSTITUTION:A radiation luminance of a measurement sample is measured at two different wavelength bands and then a specific temperature Ta and a radiation rate epsilona are obtained assuming that this sample is a gray body. Then, using this value, a proper temperature is obtained from an interpolation table which was obtained previously from a spectral radiation rate of the sam ple. The interpolation table is created by calculating the temperature Ta and the radiation rate epsilona at a representative sample temperature Ta, thus achieving a temperature measurement with less error for wide measurement targets.

Filed: 1991-12-17
Abstract: PURPOSE:To surely prevent crimes and reduce the installation cost of an elevator without installing a window at a getting-on field by installing a means for correcting an aimed floor to the contiguous floor when a waiting passenger detecting means detects that a waiting passenger is present at the getting-on field on an aimed floor. CONSTITUTION:In the theft-preventive mode time region at present (S1), the detection value of a waiting passenger detecting sensor at each elevator getting-on field is inputted (S2), and it is judged that a waiting passenger detecting sensor at the getting-on field on an aimed floor detects a waiting passenger or not (S3). When no waiting passenger is detected, it is judged that the need of theft-preventive operation is unnecessary, and the ordinary operation control is carried out. Further, if it is judged that a waiting passenger is present at the elevator getting-on field on the aimed floor, it is judged if the aimed floor registered by the cage call is the uppermost floor or not (S4), and if the aimed floor is the uppermost floor, the aimed floor is corrected by the subtraction by -1 (S5). When the aimed floor is not the uppermost floor, correction is performed by adding +1 (S6). Then, a cage position display device at the getting-on field where a waiting passenger is present is put OFF (S7).

Abstract: PURPOSE:To make it possible to form precisely bumps on a circuit to the circuit by a method wherein bump exposure of one chip is repeated while a positional error generated in a circuit formation process is corrected by a pattern recognition CONSTITUTION:A recognition mark 5 is detected and thereafter, as the distances (x) and (y) between each bump 4 and the mark 5 are determined in a design, an X-Y table 9 is driven by a numerical control and at the same time, a laser spot light is irradiated by a laser beam output device 7 and a resist at bump formation parts on a board 1 is removed by the energy of the spot light. After a necessary bump exposure ends, the table 9 is moved by a necessary distance and the next chip mounting parts 2 are searched. At this time, as there is an error in the formation of a circuit, the formed error is corrected while the next recognition mark 5 is detected by a camera 6 and the bump exposure is repeated. Thereby, the bumps on the circuit can be precisely formed to the circuit.

Title: Communication network system
Inventor: YAMAMOTO KOJI
IPC: H04W24/04
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To avoid system-down and disable call origination/reception by allowing a standby node to receive a program, data and a normality certificate signal from each control node at all times and allowing the standby ode to execute substitute processing when the standby node finds out a fault. SOLUTION: A standby node 2 sends an access signal from a signal function section 27 to each control node via an access section 23. Upon the receipt of it by a signal function section 14, the control node 1 returns a program, data and a signal certifying normality in a storage section 11 to the standby node 2. The standby node 2 receives it via the signal function section 27 and stores it to a storage section 21 to update the contents and allows a substitute discrimination section 24 to discriminate the normality of each control node. When a fault is found out, an identification number is stored in an address storage section 25 and the standby node 2 executes substitute processing based on the program and the data stored in the faculty control node via an address changeover section 24 and a selection execution section 22.  Thus, the system-down and disable call transmission/reception are avoided to improve the reliability.

Further, the matter that the diffractive optical surface is provided with plural ring zone-surfaces around the optical axis, and boundary surfaces of respective ring zone-surfaces are vertical to the spherical surface is preferred. Further, the matter that the diffractive optical surface is a binary optical surface having a stepwise section is preferred.  In such an optical system, since main light is made incident from a direction nearly vertical to the diffractive optical surface, the diffractive efficiency isn't deteriorated, and the excellent image with less flare is obtained.
