Title: Laser type method and apparatus for measuring air transmission in tunnel
Inventor: MIZUNO AKITETSU
IPC: G01N21/59
Filed: 1990-08-22
Abstract: PURPOSE:To miniaturize an apparatus and improve measurement accuracy by using measurement light which is approximate to actual lighting light and by obtaining an absorption coefficient with brightness of the measurement light which has reciprocated two times in a predetermined distance compared with brightness of reference light. CONSTITUTION:Laser light emitted from an He-Ne laser tube 12 enters an optical means vessel 13 on the right side to be converged to a laser beam 50 and separated into reference light and measurement light inside the vessel 13. The measurement light proceeds toward the left and comes against a reflection unit 16. The beam 50 which has been reflected on the reflection unit 16 and has returned is reflected in the vessel 13 to proceed again to the reflection unit 16, where it is reflected and returns. By measuring brightness of the measurement light and the reference light, an absorption coefficient is calculated. A calibration cylinder filled with clean air is provided inside a frame 11, whereby calibration of scales is possible when necessary. Further an arithmetic circuit for calculating the absorption coefficient from the brightness is included in the vessel 13. In addition a hook 19 for hanging can support a measurement unit 10 on two points.

Title: Test dot recording method and printer
Inventor: SHIMADA KAZUMITSU
IPC: B41J2/51
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a test pattern for regulating the dot recording timing accurately in a bidirectional recording printer. SOLUTION: Shift of dots being formed at the time of going motion and returning motion of a carriage 15 adjusted using a test pattern of regular dither matrix. Since the dots in the test pattern are arranged regularly in main and subscanning directions, they are viewed as a uniform pattern having no fluctuation in the gray level when they are printed at a correct record timing. When the record timing is shifted, the dot interval is shifted to cause fluctuation in the gray level. More specifically the dot record timing of a printer can be adjusted accurately depending on the presence/absence of fluctuation in the gray level. When the test pattern is a regular dither matrix providing a spatial frequency for enhancing the visual sensitivity, fluctuation in the gray level is perceptible more prominently and the accuracy of adjustment is enhanced.

Title: Evaporator for liquefied gas
Inventor: OONISHI TETSUYA
IPC: F17C9/02
Filed: 1983-11-24
Abstract: PURPOSE:To evaporate LPG liquid efficiently by erecting pressure adjusting cylinders having sufficiently large sectional area on both ends of each manifold tube in such a manner as to connect with each other. CONSTITUTION:The heat transmission area of pressure adjust cylinders 4, 5 is very small for its liquid storing quantity, and atomospheric heat is intercepted by freezing caused at the outer wall. Therefore, the evaporation quantity of LPG in the respective pressure adjust cylinders is held down to the minimum, and the liquid levels Li, Lo are very stable. The respective head pressures of liquid side manifold tube base portions F1, F2 and so on show Li-Lo under action of the pressure adjust cylinders 4, 5. LPG liquid is distributed equally to each fin tube 1 by the head pressure, and the liquid is evaporated while rising.

Title: Semiconductor relay
Inventor: SATE TOYOFUMI
IPC: H03K17/615
Filed: 1991-09-02
Abstract: PURPOSE:To realize the semiconductor relay for both AC and DC use by supplying a base current of Darlington connection transistors(TRs) when two photodiodes connected in opposite polarity coupled optically with a light emitting means connected between relay input terminals are conductive. CONSTITUTION:When an input signal is applied between relay input terminals 1, 2, photodiodes 6-9 are conductive through exposure of light from a light emitting diode 5. As a result, any of two TRs 10, 11 in Darlington connection is biased depending on the polarity of the voltage between relay output terminals 3, 4 and conductive and a current flows between the output terminals 3, 4. When the input signal is interrupted, both two TRs 10, 11 are nonconductive, the current flowing between the relay output terminals 3, 4 is interrupted. Thus, even when a DC power supply or an AC power supply is employed for a load to be controlled, the power supply is self-extincted and the semiconductor relay is formed by PN junction only and the semiconductor relay of a large capacity is easily formed.
