Title: Electrostatic charge image developing toner
Inventor: ONO HITOSHI
IPC: G03G9/097
Filed: 1992-12-18
Abstract: PURPOSE:To provide the electrostatic charge image developing toner which substantially prevents the generation of stains of copies with lapse of time and has high quality by incorporating >=1 kinds of specific compds. into the toner. CONSTITUTION:This toner contains the compds. expressed by formula. In the formula at least one of R to R denote a cyclic alkyl group and the others respectively denote a substd. or unsubstd. aralkyl group; A denote a (substd.) arom. ring residue; n denotes an integer. The cyclic alkyl group of 5 to 7C is more preferable and is more particularly the cyclohexyl group. The content of the compds. expressed by the formula in the toner is preferably 0.1 to 20 pts.wt. per 100 pts.wt. resin. The effect of improving electrostatic chargeability is not expected if the content is too low. The quality of the toner degrades if the content is excessively high and such contents are therefore undesirable.

Title: Optical sensor
Inventor: ITO HIROBUMI
IPC: G01V8/14
Filed: 1989-12-27
Abstract: PURPOSE:To reduce abberation and to improve detection accuracy by forming the front surface of a planar optical member as a prism surface, and forming the rear surface as the surface of a Fresnel lens. CONSTITUTION:Surface parts 11a and 11c of linear multiple prisms are formed at the front surface of a planar optical member 11. The prism surface parts 11a and 11c are symmetrical with respect to an optical axis O - O' and formed at the same angle. Fresnel-lens parts 11d, 11e and 11f are formed at the rear surface. Photodetectors 12, 13 and 14 are arranged at the rear side of the Fresnel lens parts. In this constitution, the luminous fluxes from detecting regions 15a, 15b and 15c are transmitted through the prism-surface parts 11a and 11c or the flat surface part 11b and inputted into the Fresnel lens parts substantially along the optical axis. Therefore, the light is inputted into the photodetectors 12, 13 and 14 without generating large abberation. The detection accuracy of the presence or movement of an object in the regions 15a, 15b and 15c can be enhanced.

Title: Thermal printer
Inventor: YAMAGUCHI KIYOSHI
IPC: B41J2/36
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To quantitatively control printing density by thermally printing a printing checking mark along with printing data and sending out the warning of printing inferiority when the density of the printing checking mark is a reference density value or less. SOLUTION: At first, the printing timing mark 6 printed on double-side thermal roll paper previously is detected by a timing mark detection sensor 4. A thermal head 2 for printing a rear surface thermally prints, therefore, a rear surface advertisement and a rear surface printing checking mark 8. Next, a thermal head 3 for printing a surface thermally prints a surface receipt and a surface printing checking mark 7. Thereafter, a printing mark detection sensor 5 detects the density values of the printing checking marks 7, 8 and these density values are converted to digital quantities by an A/D converter 9 to be sent to a CPU. When the digital convertion values of the density values are less than the lowest level of thermal printing density, printing inferiority is judged to be let know on a display part.

Title: Switching power unit
Inventor: MATSUO YASUSHI
IPC: H03K17/08
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a switching power unit which protects a transistor from damage caused by overcurrent without using the transistor of more than a necessary capacity. SOLUTION: When it is detected that collector current of a transistor 11 which constitutes a main switching transistor circuit 10 increases, a transistor 22 immediately bypasses base current of the transistor 11 and cuts off the collector current of the transistor 11. Because of this, the transistor 11 can be protected from damage which is caused by overcurrent, and when a load short circuit occurs, cutting off the collector current of the transistor 11 can prevent the transistor from being damaged by turning on a diode 31. Therefore, overcurrent does not flow into the transistor 11, and it is possible to make a device small because the capacity of the transistor does not need margin any more.
