Patent JP-S5045617-A (JP)
IPC: H04R9/04
Filed: 1974-07-25
Abstract: A loudspeaker voice coil assembly having improved power handling capability is disclosed. The voice coil is wound of rectangular cross section aluminum wire having flexible anodized coating. A thin anodized aluminum retaining cylinder is adhered to the winding of the voice coil with a thin coating of a cement. The anodization serves not only to electrically insulate the turns one from another and from the aluminum, heatradiating retainer, but also serves to enhance the efficiency of the cement bonding. Voice coils capable of continuously dissipating 150 watts rms audio power have successfully been fabricated.

Title: Manufacture of semiconductor device
Inventor: OKUMURA NOBUO
IPC: H01L21/76
Filed: 1985-04-19
Abstract: PURPOSE:To restrain a bird's beak from expanding by a method wherein, when the second oxide film is removed, the removal of the first oxide film beaneath the first nitride film by side etching process is protectively prevented by the second nitride film left on the sidewalls of three layered film and a recession in substrate. CONSTITUTION:An element separating region of three layered film comprising the first oxide film 3, the first nitride film 4 and the second oxide film 5 successively formed on a semiconductor substrate 1 is selectively opened. A recession 9 is formed on the substrate 1 by removing a part of substrate 1 exposed by the opening in the depth direction by etching process and then the inner surface of recession 9 is implanted with channel stopping ion. Next overall surface is covered with the second nitride film 17 which is anisotropically removed by etching process to leave the other nitride film 17' on the three layered film and the recession 9. Finally the second oxide film 5 and the third oxide film 10 are removed to form a new field oxide film 18 on the recession 9. Through these procedures, a bird's beak can be restrained from expanding.

IPC: G03G15/16
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To enhance the detection accuracy of a resist sensor or an automatic image density control(AIDC) sensor by disposing an elastic member so that it may come in contact with the inner surface of a transfer belt corresponding to a detecting position on the transfer belt by a detection means. SOLUTION: The elastic member 30 having elastic force is disposed to press- contact with the transfer belt 2 on the back side of a detecting part by the resist sensor 6 on the belt 2. The member 30 is fixed on a supporting base 31 attached to a bearing by a machine screw and supported by the base 31. Pressing force in a direction shown by an arrow G is applied to the inner surface of the belt 2 from the member 30 supported by the base 31. Therefore, even when a partial swelling or a partial dent exists on the belt 2, it is eliminated to make the belt 2 even by using the member 30. Thus, distance accuracy between the resist sensor 6 and the belt 2 at the detecting position on the belt 2 is secured.

Abstract: PROBLEM TO BE SOLVED: To raise immunity characteristics of a solid-state imaging device. SOLUTION: Around a package 2 where at least a solid-state imaging element 1 is housed (and at a lens fitting member surrounding it), a loop 5 of one or more turns of a conductor surrounding the solid-state imaging element 1 is formed. The loop 5 of one or more turns with a conductor forms an anti- magnetic field against a magnetic field from outside inside the loop 5, so, the magnetic field from outside is canceled with the anti-magnetic field. Thus, the inside of the loop 5 becomes no-magnetic field.

Based on the increase and decrease of these collector currents, collector currents of TRs Tr26 and Tr27 increase and decrease through the intermediary of TR Tr28, and an output signal Vout which is in-phase with the input signal Vin is outputted from an output terminal TO. When the input voltage Vin becomes lower than the reference voltage Vr, on the other hand, collector currents of TRs Tr19 Tr23 increase and decrease. Based on the increase and decrease of these collector currents, the collector currents of the TRs Tr19 and Tr23 increase and decrease through the intermediary of the TR Tr28. Then an output signal Vout having a phase opposite to the one of the input signal Vin is outputted from the output terminal TO.
