IPC: H01S3/113
Filed: 1978-06-09
Abstract: PURPOSE:To make it possible to generate a laser beam characteristic to each Q switch with a light axis used in common, by combining a Pockels cell Q switch and coloring-element Q switch with a single laser active substance. CONSTITUTION:The resonator when Pockels cell 4 is used for a Q switch is formed of reflecting surface 10, the 90 deg. corner of prism 7 with a truncated and pentagonal head, and after laser rod 2 has adequate inversion distribution, Pockels cell 4 is driven to generate a giant pulse. The light passage at this time is formed of high reflecting surface 10, laser rod 2, pantagonal prism 8 with its head truncated, polarizer 3, Pockels cell 4, and the above-mentioned corner of 90 deg.. Now, when polarizer 3 is replaced by high reflecting coloring-element cell 9 with one window material substituted with a coner cube, the resonator is formed of high reflecting surface 10, laser rod 2, pentagonal prism 8 with its head truncated, and high reflecting coloring-element cell 9 and the giant pulse can automatically be generated by causing inversion distribution to occur to laser rod 2 adequately.

Title: Display method of plant state
Inventor: SATOU YOSHIHARU
IPC: G05B23/02
Filed: 1982-04-28
Abstract: PURPOSE:To display the safety state of a plant, by calculating the approximating degree to the control value, the increment/decrement trend and the time margin and the displaying them to a CRT on the basis of data on the present data, the preceding value and the limit value is terms of important parameters of the plant. CONSTITUTION:A data storing area 3 stores the limit value data on important parameters which control the safety of a nuclear reactor 1. A computer 2 first fetches the present value A related to an important parameter from an input reading part 6 via a process input device 5 and delivers it to an arithmetic control part 7. Then the preceding value B and the limit value C are fetched to the part 7 from the area 3. Then the level difference is calculated between the value A and the value C, and at the same time the value A is compared with the value B to decide the approximating degree to the value C, the increment/decrement trend and the time margin to the value C. A display part 8 displays the important parameters on a CRT4 in patterns in each corresponding form of display. Thus, the load of an operator is reduced and a safer and better operation of a plant is ensured.

Title: Cooking utensil with steam process function
Inventor: MISHIMA MOTOMICHI
IPC: A47J36/38
Filed: 1990-03-20
Abstract: PURPOSE:To provide a cooking utensil with a steam process function for disposing of steam generated in cooking without exhausting it into a room, by providing a cooking chamber with an exhaust hole, a heat exchanger connected to the exhaust hole, a cooling device for cooling the heat exchanger and a drain pipe making connection between an outlet of the heat exchanger and the cooking chamber. CONSTITUTION:A dish is put in a cooking chamber 2 to be heated by the use of a heater 3. Steam generated from the dish is guided from an exhaust hole 8 to an inlet 5a of a heat exchanger 5. The steam guided into the heat exchanger 5 is cooled by a blast from a blower 6 and condensed into water. The condensed water drips from an outlet 5b into a drain pipe 9 to be again guided to the inlet 5a. The condensed water guided to the inlet 5a drips into the cooking chamber 2. Dry air free from steam is exhausted from the exhaust hole 12 to the outside of this utensil. Since no steam is thus exhausted into a cooking room, the utensil can be used for a built-in cooking utensil capable of being put in a unit box without an uncomfortable feeling about remarkably changed circumstances of the room and staining or dewing the peripheral part.
