Title: Optical waveguide and its production
Inventor: WATABE ATSUSHI
IPC: G02B6/13
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain an optical waveguide with good dimensional accuracy and good production efficiency by using a substrate having a groove formed by press forming and consisting of a multicomponent glass near the groove and forming a layer as a propagation region of light in the groove from a glass or a resin having a higher refractive index than that of the multicomponent glass. SOLUTION: A recessed groove 2 having about 10 μm width and depth is formed on one surface of a multicomponent glass substrate 1 (a). A glass molten liquid 3 such as silicate and polysilicate is poured onto the surface of the glass substrate 1 where the groove 2 is formed (b). The glass material is so prepared to have a higher refractive index and lower melting point than those of the glass substrate 1. Then a glass substrate 4 of the same material as the first substrate is laminated on the glass molten liquid 3 and heated in a close contact (c) to form a propagation region 5 of light (d). In the obtd. optical waveguide 10, the groove 2 formed in the glass substrate 1 acts as the propagation region 5 of light and therefore the propagation region 5 for light 5 of high accuracy can be obtained.

Title: Clinical thermometer
Inventor: SHIRASU TAKEHIRO
IPC: G01K11/00
Filed: 1987-03-13
Abstract: PURPOSE:To obtain a clinical thermometer that infants like by equipping a main body partially with a part which changes its shape when warmed with the bodily temperature. CONSTITUTION:Shape memory alloy 14 is incorporated in part of the clinical thermometer main body 2 and its material, size,and operating temperature are so selected that the alloy restores itself according to temperature examination time. When the thermometer is used, the alloy restores itself to its shape by being warmed with the bodily temperature to a prescribed temperature and then pushes up a rod 10 against a bias spring 13 to move a display plate 7 at one end of a crank 9, so that eyes 5 appear in openings 8 of a face 4. When the thermometer is removed, the memory alloy spring 14 falls in temperature into a soft martensite phase state and then the bias spring 13 push back the alloy, which therefore shrinks, so that the eyelids of the display plate 7 appear in the openings 8 of the face. This structure attracts infant's attention and the infant is willing to have a temperature examination.

Title: Construction of reinforced concrete foundation for building
Inventor: NAITOU NOBUHIKO
IPC: E02D5/34
Filed: 1980-05-06
Abstract: PURPOSE: To easily expose the iron bars of reinforced concrete by fitting a spacer capable of being easily removed into the upper part of a cylindrical iron bars assembly when concrete is poured.  
     CONSTITUTION: A spacer 5 molded of foamed styrol, wood, a metal, etc., is fitted into the upper part of iron bars 1. After concrete is placed into the iron bars 1 and hardened, the spacer 5 is removed, the ground around the foundation is digged, and the concrete above the foundation 4 is broken to expose the iron bars. Because the concrete, having a thin cylindrical form, is less in its amount and also weak in its strength, the concrete can be easily broken.

Title: Shock waveform generator
Inventor: WATANABE KATSUO
IPC: G01P21/00
Filed: 1989-03-10
Abstract: PURPOSE:To improve the flatness of a steady acceleration part of a square shock waveform by setting the set pressure of a pressure regulator of a blocking piston to a value higher than the gas pressure in a cylinder before compression due to the piston. CONSTITUTION:Since the set pressure of a pressure regulator 9 of a piston 2 is set to a value higher than the gas pressure in a cylinder before compression due to the piston 2, liquid 11 stays in the cylinder 1. When the piston 2 is moved in the cylinder 1 and the gas pressure rises to exceed the set value of the regulator 9, the piston 2 is pushed to discharge the liquid 11, and the rise of the gas pressure in the cylinder 1 is suppressed. When the gas pressure is reduced to the set value of the regulator 9 or lower, a discharge port 8 is closed but the gas pressure rises again by movement of the piston 2. Since the liquid 11 is interruptedly discharged based on the pressure set by the regulator 9 in this manner, the pressure rise in the cylinder 1 is suppressed and the shock acceleration is kept constant; and thus, the shock waveform approximating an ideal square shock waveform is obtained, and this shock waveform is obtained regardless of a small cylinder capacity.

Filed: 1985-03-26
Abstract: PURPOSE:To detect an attitude accurately by detecting inertial angular velocity by adding/subtracting a signal proportionate to driving acceleration of simple harmonic oscillation driving to/from a deviation detection signal. CONSTITUTION:A differentiator 6 generates a driving acceleration signal 6' from output 4' of a driving speed signal source 4, and a variable gain amplifier 7 generates a cancellation signal of amplitude corresponding to driving inertial force component included in a deviation detection signal 1' from a driving acceleration signal 6'.

In such a constitution, driving inertial force component included in the deviation detection signal 1' is almost removed before phase detection processing by a phase detector 3. For a low band filter 9 inserted after phase detection, necessary minimum one that can remove ripple caused by true signal component is enough for the purpose, and frequency characteristic as a device is improved.
