Abstract: PURPOSE:To apply proper linear pressure on a recording medium by providing pressure rolls which differ in diameter, and using them selectively to vary the applied pressure. CONSTITUTION:A pressure roll 2 is arranged opposite to a fixed roll 1 and held rotatably and movably as shown by an arrow X. A 1st pressure roll 3a and a 2nd pressure roll 3b are arranged between the fixed roll 1 and pressure roll 2 and held rotably on a frame 8 through a moving block 3c and a guide frame 9a. Further, the 1st pressure roll 3a and 2nd pressure roll 3b are selected by a pressure roll selecting and moving means and one of them is positioned between the fixed roll 1 and pressure roll 2. Therefore, when the total pressure of a pressure generation part 4 is equal, the recording medium is applied with different linear pressure because of the difference in diameter between the 1st pressure roll 3a and 2nd pressure roll 3b and the pressure applied by the 1st pressure roll 3a is higher than that by the 2nd pressure roll 3b.

Abstract: PURPOSE: To prevent a false detection of completion of water feed by stopping water feed completion-detecting operation when the opening of a door is detected after a predetermined period of time has elapsed while completion of water feed is not being detected, and executing water feed completion-detecting operation to detect completion of water feed at a predetermined temperature when the closing of the door is detected. CONSTITUTION: Completion of water feed is detected by a water feed completion primary- detecting means of a control circuit 26 on the basis of the fact that a temperature detected by a tray temperature sensor 17 has reached a level of a predetermined temperature or higher within a predetermined period of time after starting water feed. When the opening of a door is detected by a door switch 27 after a predetermined period of time has elapsed while completion of water feed is not detected by the water feed completion primary detecting means, the water feed detecting operation based on the temperature detected by the tray temperature sensor 17 is stopped. Also, when the closing of the door is detected by the door switch 27, the water feed completion detecting operation is executed and, when a predetermined temperature is detected by the tray temperature sensor 17, completion of water feed is detected by a water feed completion secondary-detecting means of the control circuit 26. Accordingly, the erroneous detection of completion of water feed can be obviated.

On the other hand, a laser distance meter 2 is provided downstream of the roll 4.  An arrival time of the connection point 11 is predicted by the judging device 5 and a specific region including the predicted point is measured so that the surface shape in the vicinity of the connection point 11 of the cast is detected. The detection result is calculated by a calculator 3 to judge the real connection point 11. Therefore, it is possible to automatically cut the connection point 11 with high accuracy by means of a cutting device 6.

Title: Image reader
Inventor: SATOMURA SEIICHIRO
IPC: H04N1/04
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To make a luminous quantity and a light distribution characteristics just after a light source is lighted or an emission spectrum stably by controlling a light source to be lighted in a prescribed timing when no image is read. SOLUTION: Upon application of power, a thermister 103 is used to measured a surface temperature of a tube of a fluorescent lamp and outputs a voltage corresponding to the measured temperature. Then the voltage is amplified by an amplifier 106 and the amplified voltage is inputted to a comparator 107. The comparator 107 compares the measured temperature with a prescribed value and outputs the result to a CPU 108. When the temperature of the fluorescent lamp 101 is lower than a 1st temperature, the fluorescent lamp 101 is lighted preliminarily. When the temperature of the fluorescent lamp 101 reaches a 2nd temperature, the fluorescent lamp is turned out, and when the temperature of the fluorescent lamp 101 does not reach the 2nd temperature, the fluorescent lamp 101 is preliminarily lighted till the temperature reaches the 2nd temperature.  Thus, the tube surface temperature of the fluorescent lamp at the start of image reading is kept to a temperature close to the stable temperature after the lamp is lighted and then stable reading is conducted at all times.

IPC: C04B35/00
Filed: 1988-09-14
Abstract: PURPOSE:To allow sizing in a short period of time with low noises without requiring measure to prevent explosion by using a ceramic raw material consisting of powder as a work and irradiating the raw material with laser light, then rapidly cooling the raw material by a cooling means simultaneously with heating by the laser light. CONSTITUTION:A means 5 for irradiation of laser light which emits the laser light and a means for cooling 4 which cools the work are provided. The ceramics raw material 1 consisting of the powder as the work is irradiated with the laser light 3 and is subjected to the rapid cooling by the cooling means 4 simultaneously with the heating by the laser light 3. As a result, the noise at the time of grain sizing and the danger of explosion which are heretofore of a problem are averted by not using the dissolution and agitation effect by an org. solvent for the ceramics raw material. The safe and clean grain size is possible in a short period of time by adopting the heating by the laser light and the cooling by the cooling device in place of the above-mentioned dissolution and agitation.
