Abstract: PURPOSE:To reduce the capacity of an instruction decoding means contained in a processor and at the same time to attain the use of an instruction after defining it in accordance with the purpose of a user by providing an instruction decoding means having the low using frequency at the outside of the processor. CONSTITUTION:Only the instructions having high using frequency are decoded in a processor end the capacity of an internal decoding means of the processor. The output received from an external instruction decoding means 3 is transmitted in a 1-bit serial way so as to reduce the increase of the number of pins. Then the total number of bits is reduced for the microinstructions which are sent from the means 3 for each bit by means of a means 12 which extracts the fields unnecessary for decoding the instructions end a means 13 which buries the microinstructions into the fields extracted by the means 12. Thus it is possible to reduce the capacity of an internal instruction decoding means of the processor and also to use the instructions in accordance with each purpose of a user.

Therefore, the air in the space between the fins can be sent without pressure drop. Furthermore, the air does not flee to outside by the cover, so the quantity of air does not drop, and heat radiation effect improves.

Title: Drip pan for broiler
Inventor: TOYAMA MANABU
IPC: F24C15/14
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent water from drying up in the central part of a drip pan even if the water content decreases by forming a ring-shaped upwardly swelling part around the central part of the bottom of the pan, while making it possible to reduce the amount of grime and smoke that may result and preventing thermal deformation through effective absorption of warping. SOLUTION: A ring-shaped upwardly swelling part 6 with an opening is formed around the central part 56 of the bottom 51 of a drip pan 5. Before a broiler is used, water sufficient to abundantly immerse the ring-shaped swelling part 6 and a bar-shaped swelling part 65 is poured into the drip pan 5. In this operation, either the ring-shaped swelling part 6 or the bar-shaped swelling part 65 may serve as a guide to determine the level up to which water may be poured into the pan. As the water in the drip pan 5 gradually evaporates and decreases, the top part of the ring-shaped swelling part 6 emerges, but because the width of the top part is narrow, little grime or smoke generate.  Also, evaporation is active in the area exposed to high temperature inside the ring-shaped swelling part, but additional water is supplied from outside it through the non-swelling part 64, thus maximizing the period of time before a replenishment of water is required.

IPC: B21B3/00
Filed: 1992-11-24
Abstract: PURPOSE:To provide a method for producing a supporter for a planographic plate which has sufficiently uniform unevennesses suitable for the supporter for a printing plate without the need for being particular about working precision such as cylindricity of a transfer roll and without the need for controlling change in thickness and extension of an aluminum sheet.

Abstract: PURPOSE:To easily and surely set a color of an area except an area in which a picture read out of an object to be read is formed by designating an optional color to the area other than the area in which a picture read out of an object to be read is formed. CONSTITUTION:A photoelectric converter 36 outputs picture information read out of a white reference board and an object to be read to an A/D converter 61. Upon the receipt of picture information from the A/D converter 61, an area discrimination section 49 discriminates an area of an object to be read and a background area other than the area of the object to be read in response to control information from a main control section 51. When a code number of the desired background color is inputted by the operation of a prescribed key while the mode is set to the background color mode, the discriminated background area is printed in a designated background color. Thus, the background area is filled in an optional color.
