Title: Vibration detecting set of portable vibrometer
Inventor: NODA MANDA
IPC: G01H1/00
Filed: 1983-05-20
Abstract: PURPOSE:To improve detecting sensitivity, by making the length of a probe to be the minimum required length, providing a vibration insulating part between the probe and a case, to which it is attached, providing a concave spherical part corresponding to the tip part of the probe and the like in a body to be measured, thereby reducing the mass of a detector, and increasing the value of natural frequency. CONSTITUTION:The length of a probe 4 is limited to the minimum length required for measuring work, and the weight of a detecting part is decreased. In order to improve the contact spring constant of the probe 4, a convex spherical surface is formed on a tip part 43 of the probe 4. A concave spherical surface 61 corresponding to the convex spherical surface of the tip part 43 is formed in a body to be measured 6. The concave spherical surface 61 can be a concave conical surface. Instead of forming the convex spherical part at the tip part of the probe 4, a spherical body can be bonded to the tip part. A vibration insulating body 2 is provided, and the vibration detecting part and a case 1, which is a hand-held part, are separated from the viewpoint of vibration. Therefore, the mass of the detecting part can be reduced to a large extent. The tip part 43 of the probe 4 is made to be the spherical surface and the corresponding surface to be measured is made to be the concave spherical surface or the concave conical surface. Thus the contact part becomes the surface contact or line contact, and the contact spring constant can be made high.

IPC: C22F1/16
Filed: 1979-07-11
Abstract: PURPOSE: To prevent an Se-Te alloy as a photoconducive material for an electrophotographic receptor to be made irregular in the sensitivity by heat treating the alloy at a temp. above the glass transition temp.  
     CONSTITUTION: 200g Se and 30g Te are mixed, sealed in a vacuum, held at 550°C for 2hr in a molten state, and quenched with cold water to manufacture an Se- 15%Te alloy. This alloy is heat treated at 110°C which is ≥50°C above the glass transition temp. for ≥1hr. 50μ. Thick Se layer is vacuum deposited on an Al support and on an Al support and on the layer the heat treated Se-15%Te alloy is vacuum deposited in 3μ thickness to obtain a receptor. The sensitivity of the receptor is very hardly made irregular and the irregularity is lowered to about 1/2 of that of a receptor using an untreated Se-15%Te alloy.

Title: Noise countering tube
Inventor: HITOMI HIROYUKI
IPC: H01B11/06
Filed: 1989-04-10
Abstract: PURPOSE:To prevent a peripheral device from malfunctioning due to noise by making a helical member formed out of an elastic material, having flexibility, contain ferrite of magnetic material. CONSTITUTION:Since a helical member 4, having flexibility, is flexible and can be bent, a conductive cable 3 can be covered from the upper of a sheath 3-2 with the helical member 4 twisted. Thus by covering the surfaces of the cable 3 with the helical member 4, a ferrite layer 4-1 therein absorbs electromagnetic wave noise, generated from the cable 3, and prevents it from being emitted to the outside. This eliminates influence of the noise given to the other device, and its malfunction can be prevented.

Abstract: PURPOSE:To realize an inspection device for a printed wiring board which can easily employ a standard mask board and perform inspection speedily by providing a selecting means with a memory display correcting means and also providing a monitor camera and a monitor display means independently of an inspection camera. CONSTITUTION:An image signal read by the inspection camera 71 is inputted to a defect detecting means 74 and when the detecting means judges that there is a defective shape, its signal is sent as defect candidate data to the mask matching part 82 of the selecting means 8.

In this matching, the defect candidate data is possibly absent at a coordinate position on the side of the printed wiring board although there is the pseudo defect data on the side of a mask memory. In this case, the monitor camera is moved to the coordinate position and a check is made by using the current image displayed on the monitor display means 12 to inspect whether or not there is a defect.
