Title: Copying machine with facsimile function
Inventor: OKAWA YASUNOBU
IPC: G03G15/00
Filed: 1992-11-13
Abstract: PURPOSE:To freely set an end time of a stored copy output by storing the content of facsimile communication received at night to a memory, calculating back a required time to complete an output at a setting time and starting a copy output. CONSTITUTION:When a night facsimile mode is selected by a changeover switch, a heater lamp 81 is turned off by a printer section control use CPU 79 and a reception memory is cleared. Then data at reception of a facsimile signal at night are stored in a memory 73 and the memory quantity is always monitored by a picture processing CPU 74. Then the CPU 74 sends information to a printer section CPU 79 through communication. The CPU 79 calculates back the time required for the output depending on the memory quantity based thereon, and a margin time till the set output end time is judged by information of a real time clock 82. As a result, the sequence of heater-on is entered at a point of time when the time to be outputted is judged and the copy output of the storage content is started.

Title: Light amplifier
Inventor: KURUMA JITSUSHIYUN
IPC: G02F1/35
Filed: 1989-12-18
Abstract: PURPOSE:To improve overall characteristic which can be used in the field of long-distance large-scale optical communication by obtaining distribution in excitation so that the magnitude of inverted distribution, that is, the size of a gain coefficient may be kept uniform from the input end to the output end of the light amplifier. CONSTITUTION:The gain between unsaturated fibers which is the gain from an input fiber end to an output fiber end is 15dB in the case of uniform injection, and it is increased to be 20dB by controlling current density ratio injection in three areas to be 2:1:2 without changing total current value. When input signal light is increased, the gain is lowered. However, 3dB saturation output which is defined as amplification output at a point where the gain is lowered from unsaturated gain by 3dB is 7dB in the case of the uniform injection and is increased to be 12dB by setting the current density ratio injected in three areas to be 2:3:4. In the uniform injection, the value of a noise factor is 6dB but is 4dB by ununiform injection and is approached to 3dB being a quantum limit. Then, the overall performance of the light amplifier is improved.

Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To greatly reduce occurrence of crack due to quenching of the apexes of a steel for a heat resistant valve by hot-forming an ingot into a nearly square prism so that its cross-sectional shape shows four curved apexes. SOLUTION: A cylinder 1 is introduced into an NFP forging system equipped with a universal anvil 21, 22, 23, 24. In this case, the cylinder 1 is kept at hot forging temperatures. The outer circumference of the cylinder 1 is given surface forging by drawing down simultaneously from four directions orthogonally crossing its axial direction, and worked into a nearly square prism 4 whose cross section has curved apexes 4c. In completing the forging, since the apexes are curved in the cross section of the prism 4, the thermal capacity is large compared with right angled apexes, with the inconvenience suppressed in which only the apexes 4c of the prism 4 are cooled more rapidly than its inside or other surfaces; as a result, cracking in the apexes 4c is controlled.
