Title: Manufacture of porous glass
Inventor: NAKASHIMA TADAO
IPC: C03C3/091
Filed: 1981-02-17
Abstract: PURPOSE: To manufacture porous glass having large pore volume by heat treating CaO-B 2 O 3 -SiO 2 -Al 2 O 3  matrix glass having a specified composition contg. a relatively large amount of Al 2 O 3  under specified conditions and by carrying out acid and alkali treatments.  
     CONSTITUTION: Starting materials forming a composition consisting of, by wt., 8W25% CaO, 8W30% B 2 O 3 , 45W70% SiO 2  and 5W15% Al 2 O 3  are calcined at about 1,100°C in a crucible, and the temp. is raised to about 1,350W1,500°C. After the passage of about 4hr, the resulting melt is quenched by charging into iced water to obtain matrix glass. The glass is heat treated at 600W800°C uniform temp. for 2W48hr. By this heat treatment phase separated clouded glass having a 2-phase structure is obtd. This glass is then treated with 0.5W2N hydrochloric acid at 70W90°C to extract the acid soluble component, and it is treated with 0.01W0.05N NaOH at ≤30°C ordinary temp. to remove the residual silica gel. Thus, porous glass having large pore volume is obtd.

Title: Noise filter
Inventor: HARA TOSHIHIKO
IPC: H02M1/12
Filed: 1989-02-03
Abstract: PURPOSE:To suppress noise in both normal and common modes with a small number of parts by winding two inductance coils around one magnetic core common to them so that the magnetic cores of said inductance coils are not magnetized respectively relative to the incoming current of an apparatus, and by connecting one inductance coil out of them in a homopolar manner and the other one in the direction of magnetization by electric current. CONSTITUTION:A common mode coil 3 is polarized in the direction in which circuit currents cancel each other relative to the magnetic core of said coil, and a high-permeability material is used as a magnetic material. A normal mode coil 5 is wound relative to its magnetic core in the direction in which a circuit current is applied, and has inductance not to a common mode current but to a normal mode noise. Thus, it is possible to suppress noise in both normal and common modes with a small number of parts.

Title: Objective lens supporting device
Inventor: KUWAMOTO MAKOTO
IPC: G11B7/09
Filed: 1987-02-04
Abstract: PURPOSE:To reduce warp and deflection at the time of attaching an elastic member, to improve a frequency characteristic, and to decrease an inclination of an objective lens by providing a cut bending part whose length is shorter than the execution length, on at least one of both end faces in the width direction in the elastic member. CONSTITUTION:An elastic member 66 is attached flexibly and movably in the focusing direction 1001, as a pair of upper and lower parallel springs, therefore, an optical axis of an objective lens 50 is not inclined even of it moves in its direction. A cut bending part 67 is a little shorter than execution length l of the member 66 and placed in the member 66 with a gap part 65 in both end parts, therefore, an elastic deformation of the member 66 is concentrated and generated mainly on the gap part 65. Accordingly, the bending part 69 of the cut bending part 67 is curved suitably so as to relax a stress concentration. By providing this cut bending part 67, warp and deflection at the time of attaching the member 66 to a movable member 52 and a turning member 68 are reduced and the assembly can be executed easily. Also, even against a torsional resonance, the rigidity is improved, therefore, frequency characteristics in the direction 1001 and the tracking direction 1002 are also improved.

Title: Stabilized power source
Inventor: MIYAMAE YASUHIKO
IPC: G05F1/56
Filed: 1995-02-13
Abstract: PURPOSE: To provide stable output voltage by providing a voltage holding circuit and holding the operation of a voltage compensating circuit in a state before pulse loading at the time of the pulse loading. CONSTITUTION: At the time of the pulse loading, the voltage A of a high voltage power source 1 drops with the time constant determined by the capacity of an output capacitor 2 and the resistance of a load 4. As the voltage A of the high voltage power source 1 drops, the voltage of a voltage detecting circuit 3 also drops, so a voltage stabilizing circuit 7 which monitors that is considered to drop, but when a pulse signal is sent to the voltage holding circuit 8 in this case, the operation of the voltage stabilizing circuit 7 is held in the state before the loading throughout a pulse period. Consequently, the voltage stabilizing circuit 7 does not operate during the pulse period.  A voltage compensating circuit 6 generates a compensating voltage for compensating the drop of the voltage A of the high voltage power source 1 when a pulse signal is sent, so the output voltage D(=A-B+C) becomes stable during the pulse period.

Abstract: PURPOSE:To make a ribbon have a long service life and be capable of being repeatedly used, by separating an ink layer and a resistive ribbon serving as a heat generating source for the ink layer from each other, providing a reinforcing member for the ribbon, and shaping the ribbon in a loop form. CONSTITUTION:A conductive base layer is removed from a conventional ink ribbon to obtain a resistive ribbon 1.

The resistive ribbon 1 with the reinforcing members 2 on the inner side is shaped in a loop form, and is so mounted that it is moved around an electrothermal head. Therefore, the reinforcing members 2 are adhered at such positions that the head can be opposed exactly to and brought into contact with the resistive ribbon 1, namely, the members 2 are adhered respectively to the upper and lower edges of the ribbon 1. The head supplies currents to the ribbon 1 to generate heat, by which an ink in a separated ink layer is melted, and the melted ink is adhered to a printing paper, thereby printing paper being printed.

IPC: H02G15/06
Filed: 1995-02-14
Abstract: PURPOSE: To prevent a conductor draw-out rod from being drawn out due to rotation by a structure wherein an elliptical groove and a rear circular groove are made in the shield tube in such relative positional relationship as allowing movement of a fixing pin on the side of a conductor draw-out rod. CONSTITUTION: An elliptical groove 13a' and a circular groove 18 are made radially in the inner circumferentia surface of a shield tube 13' with the circular groove 18 being made in the rear of the elliptical groove 13a'. The grooves 18, 13' are made closely each other and communicated with a pass groove 19 extending in the axial direction on the long diameter side of the elliptical groove 13a'. When a fixing pin 17 is located along the short diameter of the elliptical groove 13a' and a conductor draw-out rod 3 is pushed in, the pin 17 passes through the elliptical groove 13a' and stops at the final inserting position, i.e., at the position of the circular groove 18. When the pin 17 is drawn out, it is turned to the position of the pass groove 19 and shifted to the elliptical groove 13a'. This structure prevents the conductor draw-out rod 3 from being drawn out at a stroke.
