Title: Fluorescent lamp for visible light hardening purpose
Inventor: HIBASHI KENJI
IPC: H01J61/44
Filed: 1986-01-24
Abstract: PURPOSE:To obtain a fluorescent lamp of a high utility efficiency by applying a phosphor mixing a specific halophosphate phosphor and a specific strontium boro-phosphate phosphor over the inner surface of a glass tube. CONSTITUTION:A mixture phosphor 1 is formed by mixing an alkaline earth metal halophosphate phosphor A activated by a diatomic europium and strontium boro-phosphate phosphor B also activated by a diatomic europium. The mixture phosphor 1 is applied over the inner surface of a glass tube 2, and a circular fluorescent lamp with electrodes 3 and 3' is made in the ordinary manufacture method. Therefore, compared with a haloid lamp used for a visible light hardening light source, the ratio of the radiation energy to the lamp input to the spectrum area 400-500nm which is the scope of the effective hardening wavelength of the visible light hardening resin is made larger. Consequently, the utility efficiency can be remarkably improved.

Title: Cylinder device
Inventor: ISOBE MASABUMI
IPC: F15B11/072
Filed: 1980-02-04
Abstract: PURPOSE: To generate different outputs in response to the strength of the outer pressure by enclosing a combination of a plurality of pistons in a cylinder, and supplying a fluid such as air and the like through a valve body which can be switched in response to the outer pressure.  
     CONSTITUTION: When air is supplied to passages 19 and 24 from a 4-way port valve 25, a piston 12 doen not move because a valve body 21 closes the part between the passage 19 and a chamber B under the condition shown in the Figure. While the air supplied to the passage 24 enters into a chamber A and moves a piston 16 to the left. At this time, since the valve body 6 is opened due to the pressure difference between chambers D and E, the oil in the chamber D flows into the chamber E, and a rod 2 with a piston moves to the left with a small output. When the external force becomes large, the oil hydraulics in the chambers E and D rises. When the pressure in the chamber D exceeds a specified pressure, the valve body 21 moves up, the air enters into the chamber B, and the piston 12 moves to the left. Then, the valve body 6 is closed, the rod 2 with the piston moves to the left with the large output.

Title: Projection type image display device
Inventor: WATANABE TOSHIMITSU
IPC: H04R5/02
Filed: 1994-02-04
Abstract: PURPOSE:To compatibly reproduce rich low sounds, to provide high sharpness and to reduce the cost even when the sufficient internal volume of an enclosure can not be secured as an acoustic reproducing device built in a cabinet at a television device provided with a compact cabinet. CONSTITUTION:The internal volume of two pairs of left and right enclosures 3 and 4 built in a cabinet 1 are made different for left and right sides, and difference is provided in low pitch sound characteristics (the sound pressure output characteristics of a low pitch sound area). When plural speaker units consist of a pair of acoustic reproducing devices, unit arrangement is provided to separate the speaker unit for reproducing the basic middle sound area from the floor. Since sound pressure discharged from both the speakers 5 and 6 is synthesized at an audience position, rich low pitch sounds can be reproduced. Especially since the low pitch sound area reduces the direction feeling of sounds, a stereo feeling is not damaged. Further, by separating the speaker unit for reproducing middle pitch sounds from the floor, reflected sounds from the floor can be reduced, and high-sharpness sounds can be reproduced.

Abstract: PURPOSE:To easily expand a field of view by forming an interlocking mechanism for turning the illuminating direction of an illuminator to the field of view direction at an observation window which is obtained through a reflector interlocking with the rotation of the observation window, the illuminator and the reflector. CONSTITUTION:When an actuator 7 is driven and a moving body 8 is moved in the left direction of an arrow direction (a), the reflector 4 is rotated in the arrow (b) direction so that the incident angle theta1 of the light reflected from an object Q coincides with its reflecting angle theta2 and the reflected light is sent to the observation window 2. Interlocking with said operation, an illuminating lamp 5 is set up so that the illuminating direction is turned to the existence direction of the object Q. Thus, the object Q is irradiated by the illuminating lamp 5, the light reflected by the object Q is made incident upon the reflector 4 through an optical path E and then led into the observation window 2 through the optical path E, so that the observer can observe the object Q. Even if the field of view at the observation window is fixed, the field of view can be easily expanded.

Abstract: PURPOSE: To provide a fuel feed system for an internal combustion engine by which transient response of the engine is improved by consitituting same such that atomization and uniformity of particle distribution of fuel are promoted therein.  
     CONSTITUTION: A suction air passage 10 has a throttle valve 12 provided therein which controls the amount of suction air into an engine. A variable throtle section 16 is formed between an end face 12a of the throttle valve 12 and an inner wall surface of the passage 10. A discharge port of an injector 18 for discharging into the suction air passage 10 an amount of fuel which has been measured by a fuel measuring device 100 is opened towards the variable throttle section 16. The measuring device 100 is operatively connected to an air valve 20 to measure fuel so that the amount of fuel to be discharged is held to a constant ratio relative to the amount of air to be sucked into the engine. The fuel thus measured is fed to the injector 18 by the measuring device 100. Since the end face 12a of the valve 12 and an end face 18a of the injector are in parallel relationship to an air flow, such an air flow promotes atomization and uniformity of particle distribution of the fuel.
