Title: Tail plug for writing instrument
Inventor: MUNAKATA TETSUYA
IPC: B43K3/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To hold air-tightness when a barrel is mounted with a structure as simple as possible, and to obtain a sufficient air flowing passage at a single tail plug by forming a continuous vent part made of a recess and/or a protrusion extended in a lengthy direction of a member at a liquidtight contact part of each member in the state that the members are separated. SOLUTION: The tail plug 1 is constituted of a plurality of members of a same shape. Since an outer diameter line of a cross section of a liquidtight contact part 7 is symmetrical to a center of the plug 1 while a protrusion and recess part is formed on the part 7, both the members coincide in a shape manner when both the members are connected to obtain a liquid tight contact. In the part 7, circular arc-like protrusion 8 and recess 9 are formed as a continuous vent part capable of communicating openings of both ends of the tube when it is inserted into the tube like a throat in a press injected state. Thus, air tightness is held when the shaft is mounted, and sufficient air vent passage can be obtained at the single plug.

Abstract: PURPOSE:To enable measurement of spectral reflection characteristic of a sample and measurement at a desired angle of incidence free from effect of reflection mirrors, by performing spectrometry of light to be measured through two reflection mirrors, two parabolic mirrors and a sample position. CONSTITUTION:Light to be measured is reflected with a first reflection mirror M1 on the optical axis O2 at the right angle to the optical axis O1 and reflected with a first parabolic mirror PM1 so arranged that the axis thereof makes a line parallel with the optical axis O2 and passing through the center of a sample surface with the center thereof as focus thereof.

Thus, a comprehensive spectral reflection factor is determined. Then, a sample S is placed on a sample base, the parabolic mirror PM2 is replaced to a surface symmetrical position PM2' while the reflection mirror is shifted to M2' and the light to be measured is reflected sequentially and spectrally measured to determine a spectral reflection factor containing the sample. The use of both the measured values allows the determination of true spectral reflection factor or the like of the sample free from effect of the reflection mirror.

Filed: 1980-04-14
Abstract: PURPOSE: To sufficiently prevent interlayer peeling and eliminate the monotony of appearance by providing an enbedment layer of neodymium powder between the opaque enamel layer right above the base plate and a topcoating enamel layer.  
     CONSTITUTION: A base material 1 for casting bathtubs is heated and opaque grease is spray-coated on the under glaze layer 2 on the base material 1 and is then baked, whereby the ground color of the base material 1 is shielded by an opaque enamel layer 3. Next, the layer 3 is melted by reheating the base material 1, and neodymium powder is sprayed onto the surface of the molten layer 3. At this time, the bathtub is put in a freely tiltable frame and the sprayed surface of the base material 1 is positioned horizontal. Thence, neodymium is well embedded in the enamel layer surface in the molten state because it has a higher specific gravity than enamel, whereby an embedment layer 4 is formed. Further, while the layer 3 is in the molten state, transparent or translucent glaze is spray-coated and is baked by reheating the base material, whereby a top coating layer 2 is formed. Since the neodymium is intersposed in the layer having a thickness the bathtub shows a deep silver white color.

Filed: 1983-03-24
Abstract: PURPOSE:To provide an excellent discharging characteristic, by using a positive electrode active material made from water-washed or neutralized electrolytic manganese dioxide treated with water solution of alumino salt or the like. CONSTITUTION:Electrolytic manganese washed in water or neutralized with an alkaline solution of sodium or ammonia is mixed and treated with a solution of alumino salt in water or a mixture of aluminum hydroxide and water, and thus the positive electrode active material is provided. As the alumino salt, chloride, nitrate, or sulfate, for example, is usable. As the result, protons, sodium ions, or ammonium ions on the surface of the manganese dioxide are replaced with trivalent aluminum ions, whereby the intersecton of the two straight lines representing the relationship between the potential on the manganese dioxide and the PH value is shifted toward the acidic side and therefore the potential variation per PH is kept low in a wider range of PH values. Thus, the excellent discharging characteristic can be provided, that is, the voltage drop of the cell during its discharging is suppressed and, in particular, the increase in the impedance in and after the middle period of the discharging is made practically negligible.

Title: Optical switch
Inventor: MIYAZAWA HIROSHI
IPC: G02F1/313
Filed: 1989-03-03
Abstract: PURPOSE:To enable fast switching operation with a low driving voltage by setting a propagation distance corresponding to the 1/2 wavelength of a signal wave equal to the complete coupling length of mode coupling between optical waveguides and setting the length of the proximity between the two optical waveguides to an integral multiple of the complete coupling length. CONSTITUTION:This optical switch is equipped with the two optical waveguides 11 and 12 and a signal electrode 14 formed on an optical substrate 10. Then the propagation distance corresponding to the 1/2 wavelength of the signal wave of the same frequency with a signal wave is equalized to the complete coupling length Lo of the mode coupling between the two optical waveguides 11 and 12 in a refractive index medium which has a value equal to the difference between the effective refractive index of the signal electrode 14 to the signal wave and the effective refractive index of the optical waveguides 11 and 12 to light. The length L of the proximity between the two optical waveguides 11 and 12 is set to the integral multiple of the complete coupling length Lo. The electrode length can, therefore, be increased by utilizing the phase speed difference between the signal wave and light. Consequently, the driving voltage can be reduced and the fast operation is enabled.

Abstract: PURPOSE:To easily change light emitting quantity and color by measuring the quantity of circumferential light and sound by a sensor for detecting it, converting the measured quantity to a voltage value or current value, and supplying this voltage value or current value to each light emitting body. CONSTITUTION:When the base 8 of a lighting device A is installed to a bulb socket, the switch of a control circuit 6 is turned on, and bulbs 1-3 in a cover are lighted.
