Title: Method for preventing strength of glass bottle bottom from deteriorating
Inventor: NOZAWA MITSURU
IPC: C03C17/32
Filed: 1987-12-16
Abstract: PURPOSE:To readily and effectively prevent deterioration in strength of a bottle bottom, by coating the bottom of a glass bottle at a prescribed temperature after passing through an annealing furnace with a water-soluble resin, thermosetting the resin with the heat held by the bottle and forming a filmy coat only on the bottle bottom. CONSTITUTION:A glass bottle is formed, passed through an annealing furnace and annealed and the bottom of the glass bottle is then coated with a water-soluble resin (e.g., aqueous polyester resin), which is subsequently thermoset by heat held by the glass bottle to form a filmy coating membrane only on the bottom of the glass bottle and prevent deterioration in strength of the glass bottle bottom. Thereby, combined treatment of hot end coating with cold end coating which has hither been carried out is not required and greater preventing effects on scratching than that can be exhibited.

Title: Apparatus for measuring principal dimensions of pipe
Inventor: MIYAZAKI YASUHIRO
IPC: G01B21/08
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To correctly measure principal dimensions in a short time, by correctly detecting the position of a pipe end by an end face position-detecting plate and measuring the thickness and inner diameter simultaneously with parallel arms and an inner diameter-measuring arm. SOLUTION: A pipe A is stopped by a pipe end position-detecting plate 3, and fixed in position by a brake cylinder 3E. The upper and a lower positions of parallel arms 6 and an inner diameter-measuring arm 9 are controlled in accordance with a type of the pipe A. A stage 10 with the arms 6, 9 is moved towards the pipe A. In consequence, a pipe wall of the pipe A is held between the parallel arms 6, and the inner diameter-measuring arm 9 is inserted into the pipe. During the insertion, a pipe end position-directing sensor 5 of the stage 10 generates a pipe end detection signal when passing a position of a detection projection at a side face of the pipe end position-detecting plate 3. A distance-measuring sensor 7 and an inner diameter-immersing sensor 8 are actuated at once based on the signal. A total circumference of the pipe A rotated by a cooperating roller 2 is measured.  Elements of the pipe spaced by a constant distance from the pipe end can thus be correctly measured at once.

Abstract: PURPOSE:To omit a polarizing film and to expand an area by forming a composite film obtained by dispersing metallic grains into the mother phase of a dielectric body as a layer body held between transparent conductive films and changing a voltage to be impressed to these transparent conductive films. CONSTITUTION:As the transparent conductive films 2, 6 for holding the composite film 3, ITO, SnO2, ZnO, etc., are used and a film obtained by dispersing metallic grains in the mother phase of the dielectric body having a large electro- optical effect is used as the composite film 3. Silver is used as a metallic material to be dispersed into the mother phase of the dielectric body as fine particles because the material has a preferable dimming function. The dimming element is dimmed by changing the voltage of a power supply 7. Respective films constituting the dimming element are formed by PVD method or the like and the formation of a polarizing film can be omitted. Consequently, the expansion of the area is comparatively easy and a large element can be produced.

Inventor: MAAKU EI HORAA
IPC: G06G7/60
Filed: 1989-12-11
Abstract: PURPOSE: To realize high integration by providing a 2-quadrant multiplier, whose output signal is the product of a differential input and the difference of electric charge, and a means which charges a floating gate to a predeterminate level and discharges it. CONSTITUTION: The 4-quadrant multiplier with two pairs of differentially coupled field effect elements 29 and 30 is included which receives the differential input to generate a differential output. This cell includes also a pair of floating gate memory elements each of which has a floating gate 31 which can be programmed to a preliminarily determined electric charge level. Floating gates 31 are extended to control gates of another field effect elements, and drains of these elements are connected to the source of one of the differentially coupled pair. The current flowing through a half, namely, one side of the multiplier becomes a function of electric charge stored in the floating gate 31. Consequently, the obtained output signal is the product of the difference in electric charge between floating gates 31 and the input signal. Thus, high integration is realized.

Title: Disk loading device
Inventor: SAKO SHINICHI
IPC: G11B17/22
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a tray driving mechanism without increasing the size of a casing. SOLUTION: An upper tray 2 is moved by a pinion 21 or 22 among an unloading position T1 for unloading a disk outside a casing 1, a housing position T2 for housing the disk inside the casing 1 and a reproducing position T3 for reproducing the disk in the deep side of the casing 1. A lower tray 3 is held by the upper tray 2 by a lock lever 8 between the unloading position T1 and the housing position T2. When the upper tray 2 moves from the housing position T2 to the reproducing position T3, the holding by the lock lever 8 is released by a holding releasing rack provided in the casing 1. In the outside of the casing 1, the lower tray 3 is held by the upper tray 2 and thus the strength of the upper tray 2 is increased. Also, inside the casing 1, the holding of the lower tray 3 is released and thus only the upper tray 2 is moved.  Thus, a structure is simplified since only the upper tray 2 is driven.

Title: Power steering device
Inventor: SUZUKI KATSUHIRO
IPC: B62D6/02
Filed: 1995-11-15
Abstract: PURPOSE: To decrease control flow at nonsteering and reduce energy loss by retaining the control flow to the min. flow if a power cylinder has low load pressure, and increasing the control flow to the flow required for assistant force when the load pressure arrives at the predetermined pressure. CONSTITUTION: A flow control mechanism 2 controls flow in accordance with the load pressure P of a power cylinder. Namely, if the power cylinder C has the low load pressure P, control flow Q is retained to the min. flow Q1 ; when the load pressure P arrives at the predetermined pressure P2 , the control flow Q is increased to flow Q2 required for assistance. Therefore, in the low load pressure P range, namely, at nonsteering, only the min. flow Q1 passes through a valve mechanism 7. Decreasing flow passing through the valve mechanism 7 depresses pressure loss generated in cylinder variable throttles 7a-7d, a pipe line, etc., accordingly to reduce energy loss. The higher load pressure P at steering results in increase to the flow Q2 to obtain sufficient assistant force.
