CONSTITUTION:After floating slider 3 is positioned, when a glass disc 5 which is a simulation of a magnetic disc is rotated, a micro gap is formed. Then, when the micro gap is illuminated by a stabilizing light, interference fringes are formed which are in turn magnified by a microscope 6 to be sent to a color difference meter 8. Meanwhile, a standard white board 11 is illuminated by the same light source as the above-described micro gap, and taken into the color difference meter 8 via a microscope 9. Consequently, the color difference between the interference fringes of the micro gap and the light of the standard white board 11 is measured. This data of the color difference is matched with the teaching data stored in a color scale by the use of a computer 14, so that the micro gap can be automatically measured. Accordingly, the micro gap can be measured promptly with high accuracy, without moving or changing the light source.

Title: Electrophotographic method of plural copies
Inventor: MIMURA YOSHIYUKI
IPC: G03G13/22
Filed: 1982-10-20
Abstract: PURPOSE:To make the repeated copy, which does not damage the picture quality, possible, by forming an electrostatic latent image in an insulating layer having a high resistance to visible rays and eliminating almost the potential attenuation due to a photoreceptor and erasing the electric charge charged to a bright part of the electrostatic latent image with ultraviolet rays at the transfer time. CONSTITUTION:As primary electrostatic charge, a negative corona electrostatic charge is applied to the surface of an insulating layer 3 by a negative corona electric condenser 4 to form a charge couple on and under the insulating layer. A P type Se-Te is used as materials of a photoconductive layer 2, and its rectifying function is used to form a charge couple easily. AC corona destacization is performed by an AC coil electrifier 5 while performing the exposure of visible rays 6, and finally, the overall exposure is performed by visible rays 7, thus forming an electrostatic latent image having electric charge corresponding to brightness and darkness of a visible-ray image. The electric charge injected to the bright part of the latent image is erased selectively by ultraviolet rays; and even if plural pictures are transferred by repeating the development and the transfer of the same electrostatic latent image, good copy pictures without bright and dark fogs of pictures are attained.

Patent JP-S6076267-A (JP)
Title: Controlling method of injection speed
Inventor: MIHARA TAKASHI
IPC: B29C45/53
Filed: 1983-10-04
Abstract: PURPOSE:To control stably an injection speed by operating a flow rate control valve in accordance with the target ultimate speed in the injection section after the injection speed attains a decelerating characteristic or attains a prescribed decelerating characteristic value. CONSTITUTION:A magnetic scale 34 is attached to a striker 5 which is integral with an injection plunger 4 and a magnetic signal is detected by the sensor 35. A position signal device 36 converts the detected magnetic signal to the stroke signal of the plunger 4 and a speed signal device 37 converts a stroke signal to a speed signal. An acceleration detector 38 converts the speed signal to an acceleration signal. The point when the acceleration signal is negative is detected by a judgement circuit 39. When a molten metal 16 arrives at a gate 17, the molten metal is throttled by said gate and therefore the acceleration signal of the detector 38 turns negative and is detected by the circuit 39. A setter 40 for the opening degree of the valve prevents the decrease of the opening speed up to the prescribed opening degree. The stable control of the injection speed with good responsiveness is made possible by such mechanism.

Title: Manufacture of ink jet head
Inventor: YAMAGISHI YASUO
IPC: B41J2/16
Filed: 1980-12-25
Abstract: PURPOSE:To obtain the ink jet head wherein fine grooves are precisely formed, by bonding a substrate, wherein ink paths are provided, and an upper lid by a bonding agent comprising light hardening resin. CONSTITUTION:The fine grooves 2 which are to become the ink paths are provided on the surface of the epoxy resin substrate 1. The bonding agent 4 is applied on the bonding surface of the substrate 1 in order to bond the acrylic plate upper lid 3 to said substrate 1. The acrylic series light sensitive resin is uniformly applied as the bonding agent, and ultraviolet ray is irradiated to the resin from the top surface of the upper lid 3 for 5min by using a mercury light. Since the bonding agent 4 receives the light transmitted through a transparent upper lid 3, it is polymerized and hardened. When the bonding agent comprising such a light sensitive resin is used, heating is not required and the bonding is performed under the intact state the bonding agent is applied. Therefore, the blocking in the grooves 2, due to the oozing out of the bonding agent which is heated and whose viscosity is lowered which has aften occurred in the prior art, can be avoided.
