Inventor: KATOU KEIGO
IPC: F02M31/135
Filed: 1981-10-05
Abstract: PURPOSE:To prevent PTC elements from cracking while improving the heat generating properties thereof by a method wherein the PTC elements are brought into tight contact with the  outer side surface of a polygonal section of an inner cylinder and a plurality projections extending in the direction of the axis of the inner cylinder are provided at the centers of the inner side surfaces, respectively, of the polygonal intermediate section of the inner cylinder so  that the tight contact between the inner cylinder and the PTC elements is secured. CONSTITUTION:A hollow heat generating vessel 14 comprises the inner cylinder 15 made of a  thin metallic material and an outer cylinder 16 made of a thin synthetic resin material. The  inner cylinder 15 is made polygonal at the intermediate section thereof and the fin-like projections 90 extending in the direction of the axis of the inner cylinder are formed at the centers  of the inner side surfaces, respectively, of the intermediate section 15a. These projections 90 function as reinforcing ribs and especially when the intermediate section 15a of the inner cylinder is press-molded to become polygonal, concave sections 91 formed due to the formation of  the projections 90 become themselves stress concentrating sections so that the bending or warping of the plain side surfaces of the intermediate section 15a is adsorbed by the concave sections and therefore, a high precision surface finishing process on the intermediate section 15a  can be performed with a small pressing load. Further, since the PTC elements 33 come into  tight contact with the corresponding plain outer side surfaces of the intermediate section 15a,  respectively, with wide surface areas of contact, there is no possibility of the PTC elements  generating cracks when the elements are subjected to an external force.

IPC: G06F12/08
Filed: 1982-09-10
Abstract: PURPOSE:To exclude the retry processing which is carried out by a data processor, by giving an access to a main memory after deciding the detection of errors for the contents of an address array. CONSTITUTION:An address array 4 of a buffer memory 2a is referred to in response to a request signal sent from a data processor 3, and read-out contents are checked by an error checking circuit 7.

Abstract: PURPOSE:To optimize a film in a plate width direction by installing a film thickness gauge which measures the thickness of a film in a plate width direction, heaters which are installed in the plate width direction in a tank for material liquid of film, temperatures of which can be controlled individually and a computer for controlling the temperature of said heaters. CONSTITUTION:A film thickness gauge control section 4 begins controlling a film thickness gauge to scan it a plate width direction and at the same time, measuring a film thickness upon a command from a computer 5. Then said control section 3 outputs the film thickness data to the computer 5 based on the measurements of the film thickness in the plate width direction. The computer 5 calculates the profile of the film thickness in the plate width direction based on the film thickness value which is output and determines whether the film thickness value in the plate width direction falls within a control range using the calculated film thickness profile and the preset film thickness range. If the film thickness value falls within the control range, the computer issues a command for the maintenance of a present state to a heater control section 2. In addition, if the film thickness value doe not fall within the control range, the computer 5 calculates an appropriate set temperature of heater for a spot where the film thickness does not meet the control based on the relationship between the viscosity of a material liquid 8 for film to be influenced by temperature and the film thickness for the inclusion of such a spot in the control range. Finally the control section 2 controls the heater 1 so that it meets the set temperature.
