Title: Apparatus and method for controlling characteristic of upper illuminating light of lighting apparatus having reflector, which has prism-shaped outer surface and comprises transparent material
Inventor: MITSUCHIERU MONROO OSUTEIIN
IPC: G02B5/04
Filed: 1991-02-19
Abstract: PURPOSE: To provide a device that controls the amount of light passing a prismatic outer surface of a reflector having a total reflection prism and facilitates a change for passing a preselected amount of light that can easily be introduced into the reflector and is different from a reflector to another. CONSTITUTION: A reflector 16 has many double-reflector right-angle prisms on its outer surface, and the prisms are formed side by side along the outer surface at positions spaced at intervals. The prisms each are a double-reflection prism, and each of them has a pair of reflecting surfaces disposed so as to effect total reflection of a large percentage of the beam entering the prism from a sight source 18. For controlling the amount of light passing from the light source 18 through the prismatic outer surfaces of the reflector 16, an additive in particle form is dispersed within the transparent reflector material and serves to divert some of the beam entering the prisms into paths that intersect the reflecting surfaces at angles less than the critical angle of incidence, and thereby, the diverted beam pass through the prismatic outer surfaces.

Abstract: PURPOSE: To prevent an operation system from being switched even if a switch test is performed during the operation of a communication system. CONSTITUTION: When a switch test is not performed, the holding signal (e) outputted from a testing device 16 is set to a low level. As a result, the decision result of a switch decision circuit 13 is supplied to a control signal generation circuit 14 via NOR circuits 17 (1) and 17 (2) in this case. As a result, an operation system Y is switched based on the decision result of the switch decision circuit 13. When the switch test is performed, the holding signal (e) is set to a high level. As a result, the supply of the decision result of the switch decision circuit 13 for the control signal generation circuit 14 is prevented in this case.

Title: Inspection of uneven tightening for rush mat
Inventor: HAYATA FUMITAKA
IPC: E04F15/02
Filed: 1989-02-27
Abstract: PURPOSE:To inspect an uneven tightening of the surface of a tatami mat to perform an image processing of a video signal obtained by photographing the rush mat. CONSTITUTION:A black/white image processor 16 converts a video signal into digital from analog to be stored into a single-screen frame memory. An image 20 containing mesh-array intersection information appears black more than the perimeter thereof. Then, the video signal undergoes a binary coding image processing by a specified threshold to obtain the image 20 as binary code image containing the intersection information. Moreover, to secure a quality binary- coded image, a shading processing and a density image pretreatment are performed as require. Then, a degeneration image processing is applied so that only one pixel is left near individual intersections of the rush mat to represent each of the intersections by one pixel. Then, the number of representative points on the same mesh of individual rush is counted per fixed length along the length of the surface of the tatami mat to measure a density of the meshes. In this manner, a range of change in the density of the intersections of the mesh is marked thereby enabling accurate extraction of an uneven tightening of the rush mat.

IPC: H04L27/00
Filed: 1988-03-01
Abstract: PURPOSE:To simplify the circuit configuration of the title circuit and to detect carriers having frequency deviations like FM carriers with high accuracy by combining a re-triggerable multivibrator which can be constituted of a general purpose digital IC with a carrier detecting circuit used for the transmitter of data, picture, etc. CONSTITUTION:At a band amplifier circuit 1 having a carrier frequency deviation received carriers are selected and amplified and at a comparator circuit 2 the zero-cross point of the carriers which are sine waves is detected and the carriers are supplied to a multivibrator circuit of the later stage after the carriers are shaped to symmetrical pulses. The multivibrator circuit is constituted of retriggerable multivibrators 1-6 and detects the upper limit frequency tH of inputted carriers fC. When the DC level of the frequency fH becomes '1', the multivibrator circuit generates pulses synchronous to the carriers fC from each trigger point J1, J2, J3,-. The exclusive sum of the outputs of the multivibrators 4 and 6 is taken at an exclusive OR circuit 7 and '1' is outputted when the frequency of the carriers is normal. When the frequency of the carriers is abnormal, '0' is outputted. A monostable multivibrator circuit 8 is triggered by the output.

Abstract: PURPOSE:To prevent piling up of works by providing a light emitting device near the stand of a work and stopping a robot arm just before placing the work making a light sensor provided in the robot arm recognize light beams from the light emitting device. CONSTITUTION:When an object 8 to be carried is placed on a stand 1, a limit switch 3 makes a light emitting device 5 emit light beams. A robot hand 2 that came to place an object 9 to be carried on the stand 1 detects light beams by a light sensor 7. A robot controller 10 recognizes that a work is placed on the stand 1 by a light sensor signal 13, and the robot controller 10 gives an instruction a stop to the robot hand 2 immediately, and the robot hand stops at once. However, piling is not caused when the robot hand approaches to take up the object 9 to be carried on the stand 1. Therefore, the robot controller 10 itself makes judgement not to give instruction to stop even if the light sensor 7 of the robot hand is detected. Thus, piling can be prevented.
