Title: Marking unit
Inventor: AIDA YOSHIMASA
IPC: B41J2/44
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain a marking unit which can print a high quality character through simple structure wherein an optical head is inclined by a predetermined angle in the scanning direction when an object is printed by irradiating with a plurality of luminous flux emitted from a plurality of light emitting sections. SOLUTION: The marking unit 1 prints an easily distinguishable high quality character by emitting laser light from an optical head 5 arranged with a plurality of fibers 4 while inclining 30 deg. or 45 deg. with respect to the scanning direction thereby limiting the interval between dots constituting a character without decreasing the diameter of each fiber 4a-4g. According to the method, the scanning distance is shortened at the time of printing a character or the like as compared with a case a character is printed by converging the laser light at a point. Furthermore, pulse control is performed while shifting the irradiation timing of each laser light by an amount corresponding to the inclination of optical head 5.

Title: Cooker
Inventor: SHIMADA TAKUO
IPC: F24C7/02
Filed: 1992-12-28
Abstract: PURPOSE:To carry out a nicely finished automatic cooking by a method wherein a temperature distribution of the food is judged and a cooking means is controlled in response to an output from a food temperature sensing means corresponding to a rotary position of a rotary table. CONSTITUTION:A judgement means 8 stores temperature information of every region transmitted from a food temperature sensing means 7. Once the rotary table 3 is rotated, the judgement means 8 treats it as a two-dimensional heat image information for one screen. Data of second rotation is compared with the data of the first rotation of the rotary table 3, resulting in that in the case of heating and cooking a food 2 with a cooking means 4, a remarkable temperature rise occurs only at a food part in the got heat image and the food 2 is extracted from all the heat images of what position in the rotary table 3 is the food placed and what size does it have and the like. It judges a heating disturbance in the food 2. A control means 6 controls the cooking means 4 in response to an output from the judgement means 8. With such an arrangement as above, it is possible to carry out an automatic cooking wherein there is no sispersion in cooked food concerning the looking.

Title: Heating and fixing device and image forming device
Inventor: HIRAI MASAHIDE
IPC: G03G15/20
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To release influence of stream jetting at a fixing nip part in a moisture absorbing condition and to reduce scanning of an unfixed image by reducing calorific value on the upstream side of the nip part with respect to the calorific value on the downstream side. SOLUTION: As to a device for fixing the unfixed image by imparting heat energy of a heating body 3 to a member to be heated; the calorific value on the upstream side of the nip part is smaller than that on the downstream side. As to the body 3, a glass coating layer 7 on the upstream side of the nip part is formed thick so that the layer 7 ununiformly covers a heating resistor 6 in a direction orthogonal to the advancing direction of the member to be heated. That is, the layer 7 is formed by excessively performing screen printing once within a range that the layer 7 covers the upstream part of a heater when the layer 7 is formed. The entire thickness of the layer 7 is about 45 to 50 μm whereas the layer thickness of the layer 7 partially covering the resistor 6 on the upstream part is 60 to 70 μm.  Thus, the moisture on the upstream side of the fixing nip part is prevented from being generated so that the backward scattering of the toner developer can be reduced.
