Inventor: IKUMA KATSUMI
IPC: G09F9/35
Filed: 1985-08-30
Abstract: PURPOSE:To reduce the influence of external light and to improve the contrast of a display pattern by making the transmissivity of a front glass substrate smaller than the transmissivity of a rear glass substrate. CONSTITUTION:The transmissivity of the rear glass substrate 15 is nearly equal to that of normal glass and the transmissivity of the front glass substrate 14 is much lower than that of the normal glass. Then, external light is made incident on the front glass substrate 14 through a front polarizing plate 23 and further reflected and led out, but the transmissivity of the front glass substrate 14 is set lower, so the display screen 9 becomes dark. Therefore, the display pattern formed with light from an illumination light source 26 which is passed through liquid crystal 13, i.e. displays on a speed display part 10 and auxiliary display parts 11 and 12 appear sharply; on the display screen 9.

Title: Electrostatic detecting apparatus for paper-leaf-shaped body
Inventor: MASUDA NOBORU
IPC: G01B7/06
Filed: 1990-07-20
Abstract: PURPOSE:To perform the highly accurate detection of the thickness and the moisture absorbing state of a paper-leaf-shaped body by processing the detected electrostatic signals which are detected with an electrostatic detecting part provided in the passing path of the paper-leaf- shaped body. CONSTITUTION:When a paper-leaf-shaped body 1 passes through a passing path 2 and reaches the upper side of an insulating plate 8, the capacitance between electrodes 10 and 14 is changed. The change is applied into a first electrostatic sensor circuit 15. When an electric field (e) between second electrodes 11a and 11b and the reference electrode 10 passes through the inside of the paper-leaf-shaped body 1, the capacitance between the electrodes 11a and 11b and the electrode 10 is changed. The change is applied into a second electrostatic sensor circuit 16. The circuit 15 applies the voltage signal corresponding to the change in capacitance which is applied from a first electrode 14 into an operation correcting circuit 17. The circuit 16 applies the voltage signals applied from the electrodes 11a and 11b into the circuit 17 by the same way. The circuit 17 obtains the thickness and the moisture and water absorbing state of the paper-leaf-shaped body 1 based on the signals applied from the circuit 15 and the circuit 16. Thus, the accurate thickness of the paper-leaf-shaped body without the erroneous component due to moisture absorption and water absorption can be detected.

Title: Gas flow pressure regulating valve
Inventor: KANEDA KAZUO
IPC: G05D16/06
Filed: 1984-09-17
Abstract: PURPOSE:To aim at the stable combustion of an engine, by opening a pressure regulating inner valve installed in the same valve box as a flow regulating inner valve and thereby making gas quantity and pressure both suppliable, in case of a gas engine. CONSTITUTION:Usually, a flow regulating inner valve (a) is controlled for its opening by an actuator being controlled in conformity with an output signal out of an oxygen sensor via a valve stem. On the other other hand, a pressure regulating inner valve (b) is closed against a spring 16 because the same pressure as pressure at the secondary side acts on a diaphragm 15 via an interconnecting hole 17. Under this condition, when the secondary side pressure is suddenly dropped by engine load, the pressure dropped acts on the diaphragm 15 via the interconnecting hole 17 whereby the diaphragm 15 is pressed by the spring 16, and the pressure regulating inner valve (b) is opened via a valve stem. With this constitution, a supply for gas quantity and pressure takes place, thus the stable combustion of an engine is well secured.

Title: Felt pen of paint type having ink reservoir
Inventor: KANAO MITSUHIRO
IPC: B43K1/12
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent separation of a solvent and a pigment of oil based ink of a paint type by making a hole of a specified bore in the center of a pen core with a penpoint of a felt pen left in a specified thickness. SOLUTION: In order to prevent separation of a solvent and a white pigment of ink from each other, a hole of a small bore of about 1 mm is made in the center of a pen core, while a penpoint 1 of a felt pen is left to be about 1.5-3 mm thick enough to prevent it from being clogged with the pigment. A dead-end pipe thus formed functions as an ink reservoir 3 and the ink is supplied to the ink reservoir 3 through a supply valve 4. Therefore the ink being apt to separate passes also through a thin filter from the back of the penpoint and is supplied directly to the penpoint. Accordingly, the ink separates little and the normal felt pen being also little clogged with the pigment is obtained.  Since the oil based ink in the ink reservoir is always present at the back of the felt pen, a normal state of the ink for the penpoint is maintained at the start of writing and a letter can always be written smoothly.
