Title: Frequency synthesizer
Inventor: MATSUURA IWAO
IPC: H03L7/18
Filed: 1991-08-08
Abstract: PURPOSE:To reduce an undesired spurious component such as a reference frequency component and a TCXO frequency component by providing a filter having a prescribed pass frequency characteristic on an input of a prescaler. CONSTITUTION:An output of a voltage controlled oscillator is distributed by a distributer 1 and part is fed to a prescaler 4 via a band pass filter 2 and a DC-cut use capacitor 3. An undesired frequency component such as a reference frequency component and a TCXO frequency component is concentrated around the frequency synthesizer and the input side of the prescaler 4 is especially sensitive to the effect. Thus, the band pass filter 2 having a prescribed pass frequency characteristic is inserted to the input of the prescaler 4. Thus, the signal with less spurious component is fed to the prescaler 4 and the carrier whose spurious components id controlled is generated.

Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To generate font data, in which font elements are made to be commonly used, by decomposing the plural fonts that form one typeface and detecting similar elements. SOLUTION: A font is decomposed to elements (1). Then, they are compared emphasizing feature points (2). Next, correction is made for a starting point position, and rotation is made for a dot picture (3). In other words, the starting point position correction and the rotation of a dot picture are used to reduce the number of groups. Then, they are grouped (4), that is to say, dot picture data are made into groups for every feature point group. Thus, plural fonts which form one typeface are decomposed to elements and similar elements are detected. Furthermore, similar elements are commonly used as one data. Thus, font data, in which the elements are made to be commonly used, is generated.

Title: Amplifier circuit
Inventor: NAKAYAMA ISAO
IPC: H03F3/45
Filed: 1990-07-28
Abstract: PURPOSE:To stabilize gain by stabilizing the output of a second differential amplifier circuit by feedback control due to an operational amplifier. CONSTITUTION:A constant voltage source V5 is connected to the noninverted input terminal of an operational amplifier OP1, and the output terminal is connected to the gate of an N-channel MOS transistor N6 for controlling a drain current I0. Therefore, feedback is loaded so that a voltage VA, at the inverted input terminal can be equal to the voltage V5 of the noninverted input terminal. In this case, relative accuracy is balanced for N-channel MOS transistors N4 and N5 constituting the second differential amplifier circuit and for N channel MOS transistors N1 and N2 constituting the first differential amplifier circuit, and relative accuracy is balanced for load resistors R3 and R1. Thus, a constant value can be obtained at all times regardless of element dispersion, temperature fluctuation and power supply voltage fluctuation.

Title: Image forming device
Inventor: MORITA SHIZUO
IPC: G03G21/16
Filed: 1990-07-26
Abstract: PURPOSE:To facilitate the exchange of consumables, the maintenance and exchange of materials and jam treatment by constituting a process cartridge in such a manner that this cartridge can be moved to a 1st position where images can be formed by an image exposing means and a 2nd position where the attaching and detaching of the process cartridge and the jam treatment can be made by closing an aperture for exposing. CONSTITUTION:A frame 50 is moved by the forward rotation of a motor M1. The rotation of the motor M1 is stopped in the position where a light shielding plate 52 atop this frame changes over a photosensor S5 of a device body from on to off. Consequently, the process cartridge 30 is moved from the 1st position in the device where the images can be formed to the 2nd position where the attachment and detachment to and from the device and the jam treatment can be made, so that the process cartridge is easily removable from the frame 50. On the other hand, a motor M2 runs forward in continuation or parallel therewith and a top cap 20 rotates to open the aperture of the device body. A sectorial gear 21 presses a switch MS2 of the device body to stop the rotation of the motor M2 at the angle at which the switch is changed over from off to on. The exchange of the process materials and the jam treatment of transfer materials are facilitated in this way.

Title: Wire drive commutator motor and window opening device
Inventor: YAMADA TADASHI
IPC: B60J7/057
Filed: 1988-08-12
Abstract: PURPOSE:To open and close a window glass with approximately identical speed by arranging a pair of brush units while shifting from a reference position (normally, a general brush arranging position where the relation between rotation and torque is constant regardless of the rotary direction). CONSTITUTION:A pair of brush units 7 are supported through an insulating member on the inner face at one end section of a motor frame 2. In the drawing, arrangement of the brush unit employed in a conventional commutator motor is shown by a double dot and dash line. A pair of brush units 7 are arranged while being shifted by an angle theta from the reference position in the forward rotary direction.
