Abstract: PURPOSE:To prevent breakdown of a preheating controlling transistor by connecting a first diode, with its forward direction reversed, in parallel to the preheating controlling transistor while connecting a second diode, with its forward direction equalized to that of the first diode, in series to the first diode. CONSTITUTION:A first diode 17 is connected, with its forward direction reversed, to a transistor 13 while a second diode 18 is connected, with its forward direction equalized to that of the first diode 17, to the first diode 17. When a capacitor 4 is charged with electricity in the direction of such polarity as illustrated, it causes electric discharge by means of the diode 17 via a center tap in the primary coil 6 of an oscillating transformer 5 and thence via one of transistors, and consequently the voltage of the capacitor 4 is added between the base and emitter of the transistor 13 but it is not impressed on the transistor 13. Also when the capacitor 4 is charged with electricity in the direction of polarity against such polarity as illustrated, it is charged with electricity via the diode 18, and consequently the voltage of the capacitor 4 is added between the collector and emitter of the transistor 13 but it is not impressed on the transistor 13. This can prevent the breakdown of the preheating controlling transistor 13.

Title: Scan path
Inventor: TERAYAMA FUMIHIKO
IPC: H03K3/02
Filed: 1987-05-08
Abstract: PURPOSE:To prevent racing of data by providing a required number of stages of inverters retarding a signal passing therethrough between flip-flops forming a scan path so as to avoid the effect of clock skew. CONSTITUTION:Inverters 3, 4 comprising MOSFETs are provided between shift flip-flops 1, 2 comprising MOSFETs. Through the constitution above, a signal at a node D1b is changed with a delay more than a signal at a node D1a.

CONSTITUTION:A part of the luminous flux from the light source 1 is condensed by the condenser lenses 3a and 3b and it illuminates the plane of a film 6 as diffused light of direct light diffused by a second diffusing plate 5. Then, the part of the luminous flux is projected, for example, on an original platen glass of a copying machine, through an image-forming lens system 7 and image information of the film 6 is obtained. Since the first diffusing plate 4 is provided at the peripheries of the light source 1, which is provided between the light source 1 and the condenser lenses 3a and 3b, the luminous flux reflected by the reflecting mirror 2 among the luminous flux from the light source 1 passes through the outer peripheral region of the light source, is diffused by the first diffusing plate 4 and is made incident on the condenser lenses 3a and 3b with the luminous flux which passed through the light source 1 as indirect light. Then, the luminous flux illuminates the plane of the film 6 as a secondary light source. In such a manner, illumination nonuniformity caused by the indirect light is reduced and the illumination intensity on the plane of the film 6 is uniformized.

Title: Polyester resin for electrophotographic toner and electrophotographic toner obtained by using production method of the same
Inventor: NAKAYAMA KOJI
IPC: G03G9/087
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a toner which can be fixed at low fixing temp. without causing any problems of offset for practical use and has high fixing strength to a transfer sheet by incorporating a specified proportion of tervalent or higher valence carboxylic acids and/or tervalent or higher valence alcohols. SOLUTION: In the chromatograph measured by GPC, this polyester resin shows the max. mol.wt. in the region between >=1×10<3> <=8×10<3> . The polyester resin has Mw/Mn between >=20 and <=200 and the proportion of molecules having <=1×10<5> mol.wt. in the whole resin is >=80wt.%. The resin contains tervalent or higher valence carboxylic acids and/or tervalent or higher valence alcohols. If the peak position of the mol.wt. is <1×10<3> , the glass transition temp. decreases, which decreases the storage property. If the peak is present over >8×10<3> , the melt viscosity increases, which means the toner is not molten enough by a fixing roll and the low temp. fixing property decreases.

Abstract: PURPOSE:To provide a power equipment, in which higher harmonic components can be reduced, regardless of an ambient temperature. CONSTITUTION:When the voltage of a capacitor C16 for charging is made higher than output voltage from a full-wave rectification circuit 11, an inverter circuit 14 is supplied with power from a first capacitor C11, and a fluoresent lamp FL is lit. When output voltage from the full-wave rectification circuit 1 is made lower than the voltage of the capacitor 16 for charging, currents amplified by an inductor L11 and a second capacitor C12 are supplied from the capacitor C16 for charging, and higher harmonics are reduced. When the temperature of the equipment is increased, the resistance value of a positive temperature coefficient thermistor R11 is elevated, the voltage value of a resistor R12 is lowered, the voltage value of a capacitor C14 is reduced, and the gate voltage of a field-effect transistor Q11 is diminished. The on-resistance of the field-effect transistor Q11 is augmented, and the apparent capacitance of a capacitor C13 is lowered, thus reducing the combined capacitance of the second capacitor C12 and the capacitor C13.
