Title: Automatic sticking method for tacky polarizing plate
Inventor: NAKAMURA TAKESHI
IPC: G02F1/13
Filed: 1980-08-08
Abstract: PURPOSE:To simplify polarizing plate working facilities and to improve operation efficiency by detecting the defective of a long-sized polarizing plate during its movement, and then by cutting only the polarizing plate at constant intervals and also cutting it right after the defective is found. CONSTITUTION:A defective sensor 25 monitors the defective 3a of a polarizing plate tape 3, moving on a cutter rest 22, by a line right under a cutter 23. The sensor 25, once detecting the defective 3a, stops a feed mechanism 13 to open and move a clamp 18 back to a starting position, and also controls the feed mechanism 13 and a cylinder 24 to put the cutter 23 in cutting operation. As the defective 3a is detected, a cut 3b is made right after the defective 3a to cut a short-sized defective polarizing plate 4a. Therefore, polarizing plate working facilities are simplified and operation efficiency is improved by using a long-sized polarizing plate.

Title: Horizontal synchronizing signal detection circuit
Inventor: SUZUKI YOSHITAKA
IPC: H04N5/44
Filed: 1992-04-28
Abstract: PURPOSE:To surely detect a horizontal synchronizing signal when fast feed reproduction is performed by deciding the horizontal synchronizing signal from the OR of the output signal of a voltage comparator and a signal in which the horizontal synchronizing signal is integrated. CONSTITUTION:The OR of the signal obtained by comparing an integral value in which the AND of the horizontal synchronizing signal 1 and the signal of a horizontal oscillation circuit 3 controlled by a horizontal AFC circuit 2 is compared with a reference value at the voltage comparator 6 and the signal in which the horizontal synchronizing signal 1 is obtained at an integration circuit 7 is found. The OR goes to HIGH by setting an integration constant so that the integral value of the horizontal synchronizing signal can be set higher than the threshold value of an OR circuit 8 even when a part of the synchronizing signal is omitted when the fast feed reproduction is performed, which decides the presence of the horizontal synchronizing signal. Thereby, it is possible to surely detect the horizontal synchronizing signal when the fast feed reproduction is performed.

Title: Fluid stop valve
Inventor: SAITO SHIGERU
IPC: F16K17/34
Filed: 1986-05-14
Abstract: PURPOSE:To prevent viscous fluid from flowing into a pump by providing a valve closing when the viscous fluid acts on a housing, and a valve closing when pressure in the housing is reduced. CONSTITUTION:Since a chamber 11b in a housing 11 is under reduced pressure during the operation of a vacuum pump, a valve body 19 at the second outlet 14 is fitted in a valve seat 20. After the vacuum pump absorbs air, water reaches the inlet 12 of a fluid stop valve 10 soon. When the water acts on a valve body 15 at the first outlet 13, pushing pressure due to water flow fits a valve body 15 in a valve seat 16 to close the first outlet 13. When the valve body 15 closes the first outlet 13, pressure in the chamber 11b rises to separate the valve body 19 from the valve seat 20. Thus the water is discharged from the second outlet 14.

Title: Inspecting method for external appearance of light-emitting diode
Inventor: NISHIOKA KATSUYA
IPC: H01L33/00
Filed: 1992-04-30
Abstract: PURPOSE:To improve an inspecting efficiency by calculating a change rate between adjacent pixel signals for forming an image of an element to be inspected according to intensity of a light, comparing it with a criterion value and deciding propriety of an external appearance. CONSTITUTION:A signal corresponding to an intensity of a reflected light of an object 21 to be inspected which is incident from a photodetector 29 is input to a calculator 30.

Differentiated values of a region to be inspected of an electrode surface and a region to be inspected of a pellet surface are output to a judging unit 31 from the shape of the object 21 to be inspected. The unit 31 compares the input differentiated values of the respective regions to be inspected with respect to change states, decides improper of the object 21 if there is larger change than a predetermined criterion value, and decides proper of the object 21 if there is no larger change than the criterion value. Thus, propriety of an external appearance of the object 21 can be effectively and efficiently decided.
