Title: Smoke detector
Inventor: AYUSAWA SEIGOU
IPC: G01N21/53
Filed: 1978-03-22
Abstract: PURPOSE:To prevent excessive current from flowing into LED and maintain high reliability for a long period, by providing a limiter circuit to determine the upper limit of the current flowing in the emitter of smoke detector. CONSTITUTION:LED 2 emits lights when current is supplied from a power source 1, and a photo detector 3 directly detects the light and outputs into an amplifier 5. The difference between this output and the reference voltage sent from a reference voltae generator 9 is amplified by a differential amplifier 7, of which output is delivered into a limiter circuit 8 which determines the upper limit of the current flowing into LED 2 and then feed backs to the power source 1. The output of a scattered light detector 4 is inputted into a comparator 10 through an amplifier 6 to be compared with the reference voltage from the reference voltage generator 9. Then the output of scattered light amplifier 6 surpasses this reference voltage, the output of the comparator 10 becomes the ON state, and a switch 11 is closed on a proper time to deliver an output. Thus, besides extending the service life of LED, the high reliability may be maintained for a long period.

Title: Nozzle plate and production thereof
Inventor: KOIKE HISASHI
IPC: B05B1/02
Filed: 1992-02-19
Abstract: PURPOSE:To contrive a stable ink flying by a method wherein a nozzle is shaped into a funnel form having a cylindrical part extending at an angle of 1-10 degrees from a minimum-diameter part of an ink delivery port in an ink flying direction and a conical part extending at an angle larger than that of the cylindrical part. CONSTITUTION:A nozzle 2 in a nozzle plate 1 is shaped into a funnel form having a cylindrical part 2-a extending at an angle of 1-10 degrees from a minimum-diameter part of an ink delivery port 2-c in an ink flying direction and a conical part 2-b extending at an angle larger than that of the cylindrical part 2-a. A meniscus 3 (a contact point a) of ink 4 is formed while having its tangent line on an edge of the conical part 2-b which functions as a lead-in part for the ink 4. Because the edge of the conical part 2-b is a straight line, the contact angle of the tangent line is kept constant. The contact point of the meniscus 3 with the conical part 2-b changes with a change in printing state or physical properties of ink. However, the shape of a meniscus 3-a of the ink 4 changing in contact position from the contact point (a) to a contact point (b) does not greatly differ from the shape of the meniscus 3.

An N-channel MOS transistor 10 becomes conductive and the level of a latch mode rises and a P-channel MOS transistor 5 becomes non-conductive, an N channel MOS transistor 6 becomes conductive and the latch output signal 7 comes to the L level. Thus, a P-channel MOS transistor 8 becomes conductive, an N channel MOS transistor 9 becomes non- conductive and the output comes to the H level. Then, a latch circuit operates as if 'H' is inputted even if information which is latched till then is either 'H' or 'L'. Thus, the occurrence of errorneous writing can be eliminated.
