Abstract: PURPOSE: To obtain a dental back lighted handpiece which excels in lighting characteristic and economy by arranging a photoconductor disposed inside a handpiece body to be made up a linear bar-shaped light transmitting material from an incoming end on the side of a light source to an outgoing end on the back lighted side. CONSTITUTION: One linear glass bar is employed from an incoming end on the side of a light source to an outgoing end on the irradiation side as photoconductor B1 arranged inside a handpiece body part 1. The photoconductor B1 made up of a linear glass bar is supported securely on a support member 141 of a joint part 14 of the handpiece body at the incoming end thereof on the side of the light source while a lower part 131 of a neck part 13 of the handpiece body part 1 supported securely at the outgoing end on the irradiation side. An intermediate part between the incoming and outgoing ends is arranged within a space inside the handpiece body 1.  Thus, the photoconductor made up of the one linear glass bar prevents insufficient quantity of light and an air layer with the refractivity thereof less than that of glass on the outer circumference part functions as clad layer thereby allowing reduction in diffused light.

Title: Induction type sodium level gauge
Inventor: WATANABE MAKOTO
IPC: G01F23/22
Filed: 1989-12-25
Abstract: PURPOSE:To make exact measurement of a sodium liquid level without being affected by ambient noises, etc., by detecting the phase shift between the supply AC current of a primary coil and the excitation current of a secondary coil and measuring the sodium liquid level in a vessel from the result of the detection. CONSTITUTION:The excitation current flows to a secondary coil 2 when the AC current is supplied from an AC power source 3 to a primary coil 1. The excitation current flowing in the coil 2 is confirmed to have 90 deg. phase shift from the AC current flowing in the coil 1 when the sodium liquid level in the reactor vessel is 0%. The excitation current is confirmed to have about 110 deg. phase shift from the AC current when the sodium liquid level is 100%. The liquid level signal corresponding to the detected phase shift is, therefore, outputted from a current rectifier circuit 6 when the phase shift between the AC current of the coil 1 and the excitation current of the coil 2 is detected by a detecting circuit 5. Thus, the sodium liquid level is exactly measured without being affected by the electrical noises of the ambient.

Filed: 1990-11-29
Abstract: PURPOSE:To securely prevent an error from occurring in measurement on inspection due to lack of a fluorescent material by forming a light diffusion layer at a position corresponding to a slit of a glass tube. CONSTITUTION:In a fluorescent lamp 10 wherein a fluorescent material 14 is applied on a glass tube inner wall 11a except on a slit 14a extending lengthwise on a glass tube 11 and a reflection layer is formed outside the fluorescent material 14, a light diffusion layer is formed at a position C corresponding to slits 14a, 15a of the glass tube 11. As a result, even if the fluorescent material 14 is peeled off from the vicinity of the part C opposite to the slits 14a, 15a, the part can be observed in a so-called blur from the slit 15a side, and therefore the part in not remarkably dark. Thus erroneous detection can be eliminated even if the fluorescent material lacks.

IPC: G06F13/00
Filed: 1990-11-29
Abstract: PURPOSE:To surely keep the secret in a transmission mode by switching the image display state of a terminal equipment to a display/non-display mode when the data stored in a card are transmitted and maintaining the display/non- display mode until a new display instruction is received. CONSTITUTION:At the early stage of attachment of a data recording medium 1, a control means 4 sets the display mode at a display part of a terminal equipment A based on a prescribed initial state display mode or a display mode set based on the data recorded to the medium l. Then the communication is started with a system of the center side. Thereafter the means 4 performs the control so as to switch the screen display of the equipment A to a display/ non-display mode based on the display mode designation information received from the system of the center side. Thus a non-display mode is secured during the transmission/reception of the secret information like the private information on the owner of the medium 1, etc., that should be kept secret from the outsiders. Furthermore it is possible to deal with the existing centers by setting an instruction of the data stored in the card and without changing the hardware of the system of the existing center side.

Abstract: PROBLEM TO BE SOLVED: To improve quality of magneto-optical signals and a degree of freedom of design of an optical system and to reduce its cost by preparing a planar beam splitter generating non-point aberration and setting the major axial direction of an elliptic spot on a magneto-optical disk in non-right angle and moreover in non-parallel with respect to the direction of an information track. SOLUTION: An angle which is formed with a line 21 connecting a converging point 17 on an optical disk of an objective lens 7 to the center of a light receiving device 5 is set to 45 degrees. Since an major axial direction 12 of an elliptic spot 11 is shortened to the direction of an information track and its orthogonal direction as compared with a case when the elliptic spot is elongated in the direction orthogonal to the information track and in the direction of the information track respectively by inclining the major axial direction 12 of the elliptic spot 11 with respect to the information track, crosstalk from adjacent tracks is reduced, and moreover a resolving power in the direction of the information track is improved. Also, a lens such as an anamorphic lens imparting non-point aberration is unnecessitated by using a planar beam splitter 3.  The planar beam splitter 3 is inexpensively obtained.
