Title: Polarizing film prism measurement device
Inventor: SUGAWARA MASAOMI
IPC: C08L55/00
Filed: 1982-03-20
Abstract: PURPOSE:To measure the performance of a polarizing film simply and certainly by forming parallel S- and P-polarizing light beams through an polarizing film prism that is freely rotatable round the optical axis as its center and receiving transmission and reflection lights obtained by projecting the parallel polarized beams to the polarizing film of a work. CONSTITUTION:If a polarizing film prism 8 is rotated by handle 19 by 90 deg. round an optical axis 9 as its center as one body with a polarizing film supporting member 17 that is supported rotatably by a bearing 16, the parallel light flux formed by laser light source 2 and lens system 10 and so on becomes S-polarizing light and P-polarizing light. Those parallel polarized lights are directed to a work 21, etc. provided with a polarizing film 25, and reflected on the reflection face 24. The S-polarizing light is reflected by the film 25 and received by a light receiving device 5, and the P-polarizing light is received by a device 6. From those light receiving, A/(A+B) based on a measured reflection value A and a measured transmission value B is calculated, and this gives simply and certainly the judgement of the performance of a polarizing film.

Title: Lighting device for emergency light
Inventor: MURASE AKIRA
IPC: H05B37/02
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To make a relay circuit simpler and cheaper by connecting a thyristor, a thermistor, and the like in series with the relay circuit, and causing a lamp to turn on when an earthquake sensor is operating and to turn off automatically after a certain time. SOLUTION: While a vibration sensor 4 is operating, a thyristor 3 carries a current, a current is supplied to a relay coil 7, and a relay contact 8 is closed to turn on a lamp 5. With the lamp turned on, the thyristor 3 is short-circuited via the contact 8 and a thermistor(Th)9 and restored to an open state, but the coil 7 is kept operating by a current flowing therethrough via the Th9. The Th9, having a positive temperature coefficient, is increased in internal resistance with rise of temperature, and is heated to high temperatures while the lamp 5 is on, so that the coil 7 is decreased in current and starts opening action. Therefore the lamp 5 is turned off and the Th9, with its current becoming zero, is cooled by natural heat dissipation and automatically restored to its first state after a certain time. Thus a device can be constructed at low cost using a simple circuit.

Title: Liquid-discharging device
Inventor: KITANAKA MASAKAZU
IPC: F15D1/08
Filed: 1993-02-09
Abstract: PURPOSE:To enable discharging a liquid even of medium or high viscosity in a state of fine particulates and at a high velocity by applying pressure to the liquid mechanically separated in a fine hole. CONSTITUTION:A liquid-separating tape 2 undergoes forced broadening in the distances between guide holes 15a, 15b and an orifice 16 is opened when the tape passes an opening sprocket 10 in a reservoir tank 3 of liquid 4. An opening sprocket 11 closes the orifice 16 and makes it contain a specific amount of liquid 4. The orifice 16 containing the liquid 4 is brought directly under the tip 6 of a nozzle. On the other hand, an object 8 for coating held on a movable table 7 is brought for the spot for coating to be positioned directly under the tip 6 of the nozzle. Then by ejecting compressed air from the tip 6 of the nozzle under a fixed pressure P against the liquid 4 contained in the orifice 16 the liquid 4 can be discharged out of the orifice 16 and applied onto the object 8 for coating without involving threading. After this coating, the liquid- separating tape 2 is moved forward, bringing over the next orifice 16 containing the liquid 4.

Title: Image forming device
Inventor: TAKEHARA ATSUSHI
IPC: G03G15/01
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device capable of extending the life of a photoreceptor for monochromatic black with high use frequency so that it last as long as the lives of remaining photoreceptors by making the film thickness of the photoreceptive layer of the photoreceptor for the monochromatic black greater than the film thicknesses of the photoreceptive layers of the photoreceptors for other development colors. SOLUTION: The film thickness of the photoreceptive layer of a photoreceptor for monochromatic black K is made different from the film thicknesses of the photoreceptive layers of remaining photoreceptors 6 for yellow Y, cyan C, and magenta M. For example, the film thickness of the photoreceptive layer of the photoreceptor 6 for the monochromatic black K is 30 μm and the film thickness of the photoreceptive layer of each of the remaining photoreceptors 6 for the yellow Y, cyan C, and magenta M is 15 μm as usual. Thus, by making the photoreceptor 6 for the monochromatic black greater in photoreceptive-layer thickness than the photoreceptors 6 for the other development colors, the life of the photoreceptor 6 for the monochromatic black with high use frequency can be extended in comparison with the lives of the photoreceptors 6 for the other development colors.  Therefore, the photoreceptor 6 for the monochromatic black is prevented from reaching the end of its life early.

Filed: 1983-03-19
Abstract: PURPOSE:To indicate the abnormality of a preheating device in distinction from other abnormalities by providing an energizing means which energizes a preheating abnormality display means to indicate the preheating abnormality when a time-out signal from a time-out signal output means is received before the reception of a preheating completion signal from a preheating completion signal output means. CONSTITUTION:When a power switch 1 is turned on, a timer 3 is started. While the timer 3 is operated, its output is ''0'', and therefore, the output of an AND circuit 6 is ''0'' independently of the output of a temperature detector 5, and nothing is displayed on a preheating abnormality display device 7. The temperature detector 5 outputs ''0'' when the preheating temperature due to a fluorescent lamp preheating device 4 exceeds a prescribed value; and if an abnormality occurs in the fluorescent lamp preheating device 4, the preheating temperature due to the preheating device 4 does not rise, and the output of the temperature 5 is ''1'' as it is even if the output of the timer 3 is changed from ''0'' to ''1'' after a a time-out time T from power-on. Consequently, both inputs of the AND circuit 6 become ''1'', and the output becomes ''1''. The preheating abnormality display device 7 reports the abnormality of the fluorescent lamp preheating device.
