Inventor: USAMI TADASHI
IPC: F23N5/20
Filed: 1990-01-30
Abstract: PURPOSE:To prevent a user from being woken up before rising time due to operation noise when a hot air room heater is used in a timer operation mode in a bedroom by a method wherein an operation state, for example, a combustion amount, during pre-operation effected before a set time of a timer is selectable. CONSTITUTION:An operation state indicating means 2 indicates a high combustion amount when a room to be heated is a living room and a room is wide and operation noise is capable of being ignored. When the room to be heated is a bedroom and a room is narrow and a user is nervous about operation noise, a low combustion amount is indicated. A control means 3 controls a combustion means 4 based on input information from an input means 1 and the operation state indicating means 2. For example, when a high combustion amount is indicated by the operation state indicating means 2, the combustion means 4 is operated in a state that a combustion is maximized. Through the generation of noise is increased, a time in which a room temperature is increased to a set value is shortened, and operation takes places in a state that an energy efficiency is highmost. When a low combustion amount is indicated by the operation state indicating means 2, the control means 3 operates the combustion means 4 in a state that a combustion amount is low, and though a time in which temperature is increased to a set value is increased, the user is completely prevented from being nervous to operation noise.

Abstract: PROBLEM TO BE SOLVED: To improve heat resisting property and handlability while preventing formation of environmental hormones (extrinsic endocrine disrupters) by a method wherein a heat-resistant container such as the one for instant noodles is formed of an inner container made of a heat-resistant plastic by molding and an outer paper container wrapped round the inner container from the outside and an air layer serving as a heat-resistant layer is formed between the inner and outer containers. SOLUTION: For an inner container 1 molded in a vertically-long cup-like shape, a number of ribs 2 are formed vertically at the outer circumferential face of its trunk part. The inner container 1 is made of heat-resistant plastic by injection molding or the like into a united body. For the heat-resistant plastic, a material such as heat- resistant PET which does not contain environmental hormones (endocrine disrupters) is used. Furthermore, an outer container 3 made of paper is wrapped round the outer circumferential face of the inner container 1. Since a large number of ribs 2 are formed between the inner container 1 and the outer container 3, an air layer 5 is formed between both containers.  Therefore, the air layer 5 serves as a heat-resistant layer, and heat is not transferred to the outer container 3 even through a hot water is poured into the inner container 1, preventing the outer container 3 from becoming hot and making handling easy.

Title: Stop device in middle of capsule conveyance flow passage
Inventor: NAKAYAMA TAKAYUKI
IPC: B65G51/01
Filed: 1987-02-02
Abstract: PURPOSE:To precisely and rapidly stop a capsule at a given position, by a method wherein a stop flow passage, feeding a capsule or fluid used for stopping an object, is connected in a position located down a line from the connection part of a discharge flow passage. CONSTITUTION:When a work approaches a given stop position 2, the valve of a discharge flow passage 5 and the valve of a stop flow passage 6 are opened by means of a control device. Even when a capsule C passes the stop position 2 by dint of inertia, a conveyance flow is discharged through the discharge flow passage 5 by means of an opening 3, and a conveyance force, by which the capsule is conveyed rightward over the stop position 2, is rendered ineffective. Further, since a stop flow coming in through a stop flow passage produces a brake force, the capsule is pushed back. When it is pushed back and stopped, a conveyance flow and a stop flow run through a gap between a conveyance flow passage 1 and the capsule C, and are uniformly discharged through an opening 3 to the discharge flow passage 5, and thereby fluid pressures before end after the capsule C are balanced with each other to maintain its position.

Title: And device therefor power residue arithmetic operation method
Inventor: ISHII SHINJI
IPC: G09C1/00
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To enable protection against such a timing attack that a secret key is found by using the same parameters as an attacking method for open key ciphering making good use of power operation by varying the delay time of a critical path by propagation delay by power residue operation. SOLUTION: A power residue arithmetic operation part 201 has a delay time adjustment part 202 and a delay time determination part 203 and then supplies a necessary irreducible delay time to the delay time adjustment part 202 to vary the operation time by power operation. A random number generation part 204 generates a random number so that the delay time determined by the delay time determination part 203 becomes random, and supplies the random number generated by the random number generation part 204 to the delay time determination part 103. The random number generated by the random number generation part 204 is determined by the input of an initial value. Consequently, the protection against a timing attack having a high risk becomes effective as the attacking method for open key ciphering making good use of the power residue operation.
