IPC: G01D3/10
Filed: 1985-04-18
Abstract: PURPOSE:To detect movement of a pointer surely and stably by providing a light sensor at a position opposite to the pointer outside of the front glass and providing the light sensor at a tilt angle to the front glass. CONSTITUTION:Light sent out from a light emitting section passes through the front glass 3, reflected by the pointer 1, or dial 2, passes through the glass 3, received by a detecting section and outputted to outside by a cable 11. Light sensors 6, 7 are provided at a tilt angle to the glass 3. Thereby, it is possible to make light emitted from the light emitting section of sensors 6, 7 and reflected by the glass 3 not to be received directly by the detecting section. On the other hand, light came in from the glass 3 and arrived at the dial 2 is reflected diffusively and a part of it is received by the detecting section. By using diffused reflecting type sensors 6, 7 and considering reflection of a uniform glass of small unevenness, movement of a pointer can be caught by a dial of ordinary meter. For interception of sunlight etc. from outside, use of an acrylic plate 10 is considered.

This molten steel is charged together with a flux contg. metallic Al through an immersion nozzle into a mold for casting of <=1.5 flatness ratio and the molten steel in the mold is agitated electromagnetically by a constant magnetic force. As a result, deoxidation is intensified and accelerated by the c, Mn and Al that the molten steel per se possesses, and rotating forces are given to the oxide and foam formed in the mold, whereby the flocculation to a solidified shell is suppressed. In this state, the molten steel is drawn out continuously downward and is solidified, whereby the intended weakly deoxidized steel is produced.

Title: Load cell
Inventor: NISHIYAMA YOSHIHISA
IPC: G01L1/22
Filed: 1983-05-13
Abstract: PURPOSE:To prevent decrease in gain, by connecting a correcting capacitor to a resistor for correcting temperature and sensitivity coefficients in parallel, thereby correcting the delayed phase of an output voltage by utilizing an advanced phase. CONSTITUTION:An output voltage vL of a bridge circuit 4 is inputted to an AC amplifier 7 having a gain Gs. Its output Gs vL and an output ve through a transmitter 8 are inputted to a synchronous detector 9 together. Synchronous detection is performed by utilizing the fact that the ve and the vL have the same phase, and they are converted into a DC voltage. A correcting capacitor Cx is connected to a resistor Rs in parallel. When a load such as the AC amplifier 7 is connected to a load cell, the output voltage vL tends to delay in phase. Owing to the presence of the correcting capacitor Cx, however, the phase is advances, and the delayed phase of the output voltage vL can be corrected.

Title: Levitation controller for carrier
Inventor: NODA AKITAKA
IPC: B60L13/06
Filed: 1989-04-03
Abstract: PURPOSE:To perform levitation control of a carrier stably by correcting the gap length, detected through a detector, to be equal to a predetermined value based on the detected gap length every time when the carrier is fixed periodically on a rail through a fixing device. CONSTITUTION:When a carrier travels, while being levitated, on a rail 1 then stops at a predetermined position and fixed to the rail 1, correcting operation is carried out. Assuming that the output Gb from a gap length detector 4 is reduced to 1.5V (normal level is 2V), for example, due to variation of characteristic of the gap length detector despite of actual gap length of 2mm. Although G=1.5V at the instance when a relay contact RY1a closes, a subtracting/ integrating circuit continues integration until Gr-G=0 is satisfied and balanced state is achieved at a time point when Gc 1.33V. Consequently, output from a multiplier MPY goes to 2V (G=2V) and a corrected true value is obtained from the gap length detector 4.

Title: Production of mask for exposure
Inventor: HOSHI KEIICHI
IPC: G03F1/68
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To make the opening side of a light shielding film uniform within the plane. SOLUTION: A resist film 4 is formed on a quartz substrate 2 on which the light shielding film 3 is formed (a). This resist film 4 is patterned by executing development by a spraying method after electron ray exposure (b). The flow rate of the developer in development is controlled (the flow rate is decreased), by which the resist film opening size 101 in the peripheral part is made smaller than the opening size in the central part. The light shielding film 3 is patterned by RIE (c). The light shielding film opening size 102 in the peripheral parts tends to be formed larger than the opening size in the central part with RIE, but the resist patterns are previously so formed as to offset this tendency and, therefore, the light shielding film opening size 102 is made uniform within the plane. The resist film 4 is peeled and removed (d).
