Title: Temperature controller for spindle head of machine tool
Inventor: ROTSUKAKU TADASHI
IPC: B23Q11/14
Filed: 1984-02-08
Abstract: PURPOSE:To aim at stabilization in the mechanical accuracy of finishing, by sharply shortening the time required till temperature in time of starting the operation of a machine tool spindle gets stabilized, while controlling the temperature of a machine tool spindle head so accurately even for a raviation in its operating conditions. CONSTITUTION:Since temperature tH in a hob head at a start of operation in a machine is designed to be lower than the sum of machine body representative temperature tM and the specified setting deviation temperature DELTAtP, a temperature differential deltat=(tM+DELTAtP)-tH is large enough, therefore a DC power 20 is controlled for its on-off operation with such a high frequency pulse signal as shown in (b). As a result, average time in an ON state is large, and lubricating oil passing through a heat exchanger 12 is amply heated by a plate heater 18, flowing into a head 3, whereby temperature in the head 3 rapidly goes up. When this temperature goes up like this, the temperature differential deltat comes small whereby the DC power 20 is controlled for its on-off operation with such a low frequency pulse signal as shown in (a), making its heating average time smaller. For this reason, heating for the lubricating oil is checked. Accordingly, even if preheating for the lubricating oil takes place, there is no overshooting in the heating.

Title: Optical circuit
Inventor: ITOU MASATAKA
IPC: G02B6/126
Filed: 1982-02-10
Abstract: PURPOSE:To obtain an optical circuit of a small size and simple constitution wherein the propagation phase constants of a TE wave and a TM wave are coincident by providing a regulating film on the top surface of a waveguide layer in which double refraction is generated. CONSTITUTION:A regulating film 3 is provided on a waveguide layer 2 in which double refraction is generated. The addition of the regulated film contributes to an increase in the equivalent refractive indices nTE and nTM of a TE wave and a TM wave, and since the nTM is increased at a higher rate than that of the nTE with a corresponding decrease in DELTAneff=nTE-nTM, the position where the phases match moves to the t'0 on the left side as shown by a broken line and the extent of the movement can be selected by the size in the thickness t' of the regulating film. The errors in setting of the film thickness or double refraction generated in the manufacturing stage of the waveguide layer are corrected by setting the thickness of the regulating film suitably, whereby the difficulty in the manufacturing stage of the conventional waveguide is eliminated and reliability is improved.

Title: Recorded material
Inventor: MOROHOSHI NAOYA
IPC: B41M5/00
Filed: 1986-02-03
Abstract: PURPOSE:To improve an image obtained by an ink jet recording system simulta neously in color developing properties, resistance to light and water, by containing a silica which has been surface-treated with a silane coupling agent. CONSTITUTION:A silica which has been surface treated with a silane coupling agent is contained in the recorded face of a recorded material, thus remarkably improving the light resistance of an image made of a water-soluble dye. The silane coupling agent having organic functional groups of epoxy, glycidoxy, amino, mercapto, or methacryl is especially preferred. In an ink jet recording system in which a recording image is formed by using a water-soluble ink, a pigment or filler of high surface hydrophobic properties is not preferable for the content of the recorded material because of the decrease in ink absorp tion and the bleeding of dots. The silane coupling agent having organic func tional groups of not quite high hydrophobic properties is desirably used. The silane coupling agent of a simple or mixed condition is used 0.2-15wt% in relation to 100wt% of the silica. The silica is added to the recorded material approximately 5-30pts.wt. in relation to 100pts.wt. of the recorded material.

Title: Flow rate detecting device
Inventor: OZAKI YUKINORI
IPC: G01F1/115
Filed: 1984-02-06
Abstract: PURPOSE:To make flow-rate resistance very small, by providing linear blades at the blade tip parts of the first curved blade, which axially turns a fluid to be detected, and the second curved blade, which is provided at a downstream position in a 180 deg. point symmetrical manner with respect to the first curved blade. CONSTITUTION:A blade tip part 13 of an arc blade 11, which is the first curved blade that axially turns a fluid to be detected, is constituted of a linear blade, which is approximately in parallel with respect to an arrow 14 indicating the flowing direction in a flow path. An arc blade 16, which is the second curved blade, is provided in a 180 deg. point symmetrical manner with respect to the blade 11 at the downstream from a magnetic ball 15. A blade tip part 17 of the blade 16 is also formed by a linear blade which is approximately in parallel with the flowing direction 14. When the fluid to be detected flows in from the direction of the arrow 14, the fluid to be detected is aligned by the linear blade of the blade tip part 13 and flows along the arc blade 11. Thus the fluid is axially turned. As a result, a magnetic ball 15 placed in the turning flow is turned in a vertical plane with respect to the flow direction 14. The number of turning of the ball 15 is proportional to the flow rate. Therefore, by counting the number of turning of the ball 15, the flow rate can be measured.
