Title: Cooking utensil
Inventor: KURIHARA SHIGEO
IPC: F24C7/02
Filed: 1987-11-06
Abstract: PURPOSE:To prevent decrease in the accuracy of sensing temperature of food by providing an infrared ray sensor which receives infrared rays from a food through a small opening and outputs a signal which corresponds to the temperature of the food and a ceramic member which is of the type of generating heat by itself and closes the small opening and passes the infrared rays through itself. CONSTITUTION:A small opening 4 in the upper wall face 1a of a heating chamber through which infrared rays from a food 2 passes is closed by a ceramic member 7 through which infrared rays pass to prevent an infrared sensor 6 from being stained by the steam from the food 2 and its small pieces, etc. Further, for the dirt on the ceramic member 7 which closes the small opening 4 an electric current is passed by a pair of electrodes 8 and 8 through the ceramic member 7 in order to generate heat in the ceramic member 7 in itself so that the dirt burns and falls down. Accordingly the accuracy of sensing the temperature of a food by means of the infrared ray sensor 6 does not fall by the steam from a food, small food pieces, etc. Further, the constitution to clean the dirt on the ceramic member 7 is only by generating heat in the ceramic member so that the construction is very simple.

Filed: 1988-11-08
Abstract: PURPOSE:To improve the wear resistance of the title alloy by increasing the amt. of Si in an Al alloy having specific compsn. to which specific amounts of ceramic grains are composed to a specific range. CONSTITUTION:The Al alloy is formed by incorporating, by weight, 5 to 20% ceramic grains into an Al alloy constituted of 20 to 40% Si, 1 to 4% Cu, 1 to 2% Mg, 5 to 10% Fe and/or Ni and the balance Al.

Title: Production of high b-containing austenitic stainless steel hot-rolled plate
Inventor: MORIKAWA HIROSHI
IPC: C22C38/54
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To produce a high B-containing austenitic stainless steel hot-rolled plate preventing the development of alligator crack in high productivity. SOLUTION: A steel ingot of the austenitic stainless steel containing 0.6-2.0% B is bloomed or forged and heat treatment to the obtd. intermediate slab is executed to remove the residual stress developed at the time of blooming or forging. Successively, after shearing in the longitudinal direction of the intermediate slab with gas-cutting, hot-rolling is executed. In the heat treatment, it is desirable to keep the intermediate slab to the range of 900-1,200 deg.C. In stead of the gas-cutting, the intermediate slab can be shorn with a mechanical cutting by using a band saw. In this case, the heat treatment for removing the residual stress can be saved. The crack causing to the alligator crack is not developed on the gas cutting surface or the machine-cutting surface of a small slab.

IPC: G06F9/38
Filed: 1988-11-11
Abstract: PURPOSE:To maintain successiveness and to simultaneously process plural instructions by synchronously processing the plural combined instructions by a pipe line between plural operand reading means and plural arithmetic units. CONSTITUTION:An instruction fetch stage 500 simultaneously reads the plural instructions from a cache memory 520 for instruction.

Then, when there is a branching instruction, a branch forecasting buffer 521 is accessed and a branching direction is determined. Further, in a decode and combine stage 503, the two instructions are simultaneously decoded and based on a decoded result, it is decided whether the instructions can be combined or not. The combined instructions are synchroniously executed by two pipe lines. The condition of an arithmetic result in each pipe line is merged according to the order of the instruction and reflected on only one state register. Thus, the successiveness is maintained and the plural instructions can be simultaneously processed.
