Title: Sound volume adjuster
Inventor: SUGAWARA KAZUAKI
IPC: H03G3/10
Filed: 1990-10-23
Abstract: PURPOSE:To prevent the deterioration of sound qualities which are reproduced outputs by providing a level changing means which changes the level value of input signals and a differential amplifier and setting the utilization factor of the input signals at '1' at the time of a large and small sound volumes. CONSTITUTION:This sound volume adjuster is provided with a variable resistor VR and differential amplifier 6a and input signals Vin are directly inputted to the noninverted input terminal (+) of the amplifier 6a. On the other hand, the input signals Vin are also inputted to the inverted input terminal (-) of the amplifier 6a through the resistor VR. At the time of a large sound volume, the input signals are directly inputted to the noninverted input terminal side of the amplifier 6a and input signals obtained through the level changing means VR are inputted to the inverted input terminal side. At the time of a small sound volume, input signals which are sufficiently attenuated by the level changing means VR are inputted to the inverted input terminal side. Accordingly, the utilization factor of the input signals becomes '1' at the time of a large and small sound volumes. Therefore, noise can be prevented from being emphasized.

Title: Destaticizing method for electrophotographic sensitive material
Inventor: KINOSHITA NAOYOSHI
IPC: G03G21/06
Filed: 1986-11-28
Abstract: PURPOSE:To effectively destaticize a photosensitive body by superposing a DC voltage having a polarity opposite to that of the photosensitive body to an AC voltage and applying them to a separating charger and increasing the DC voltage if a transfer paper does not exist between the photosensitive body and the separating charger. CONSTITUTION:The AC voltage is applied from a terminal 11 to a separating charger 5 simultaneously with start of a main motor, and a terminal 13 is turned off to superpose 100V DC bias voltage to the AC voltage because a transfer paper P does not exist between the separating charger 5 and a drum 1. When printing is started, a roll 14 feeds the transfer paper P at a proper time and is detected by a sensor 15, and a timer turns on the terminal 13 after a prescribed time and a relay 23 is switched to reduce the DC bias to 500V. After the transfer paper P passes, the timer turns off the terminal 13 after a prescribed time to switch the relay 23, and 100V is superposed again. By this constitution, the conventional separating charger is used to effectively destaticize the photosensitive body, and reduction of lives of the photosensitive body and a cleaning blade is prevented.

Abstract: PROBLEM TO BE SOLVED: To make an emitter area far smaller than a size determined by the min. size of a mask by forming the emitter region of a transistor like a ring. SOLUTION: Among oxide films on a p-type base layer 2, an islandlike oxide film 10 is left on specified surface portions of this layer 2. A silicon nitride film 11 is formed and anisotropically etched to remove other portions of the nitride film 11 leaving the nitride film 11 on the walls of oxide films 4, 10, thus forming a ring of this film 11 surrounding the island-like oxide film 10. A heat step is applied to additionally form the oxide film 4, without growing the oxide film 4 at the junction of the nitride film 22 and silicon surface. The nitride film 11 is removed to form two ring-like areas having no oxide film and the same width as the thickness of the nitride film 11; one around the oxide film 10 on the base region 2 and the other outside the base region 2.  The outside is for introducing an ntype impurity of the collector and the inside is for introducing an n-type impurity of the emitter.
