Title: Heat accumulating surface material
Inventor: HORIE AKIRA
IPC: F24F1/00
Filed: 1987-10-27
Abstract: PURPOSE:To enable a heat accumulating material to be utilized in cooling and heating operations with one type of a latent heat accumulating member by a method wherein a thermal insulating material layer is overlapped on a heat accumulating layer using the latent heat accumulating member having a phase transition point in a desired range of room temperature through a heater. CONSTITUTION:Heat accumulation members having within a container 1b a latent heat accumulation member 1a of which transition point is within a temperature range of 25-28 deg.C are overlapped to each other to construct a latent heat layer 1, and a thermal insulation layer 4 is overlapped on one surface of the thermal accumulating layer 1 with a heater 3 being held between them. When a room temperature is lower than a phase transition point of the latent heat accumulation member 1a, the latent heat accumulation member 1a shows a phase variation to discharge a latent heat. In turn, when the room temperature is more than transition point, it may absorb the latent heat to perform a cooling operation. In order to cause the latent heat accumulation member 1a to be operated, it is necessary for its transition point to be within a range from a maximum temperature to a minimum temperature of the room temperature. In winter season, heat is generated by a heater 3 to store it as a latent heat in the latent heat accumulation member 1a, thereby heating with low cost operation is realized.

Title: Magnetic recording medium
Inventor: TAKAMATSU SHIGERU
IPC: C09D5/23
Filed: 1985-12-04
Abstract: PURPOSE:To provide a magnetic recording medium having a good electromagnetic conversion characteristic and low light transmittance by adding Co-gamma-Fe2O3 particles and CrO2 particles having respectively specific values or above of BET values as ferromagnetic particles in a specific quantity relation to a magnetic coating compd. CONSTITUTION:The CrO2 particles having >=20m<2>/g BET value are made to co-exist in the magnetic coating compd. at 5-25wt% based on the weight of the Co-gamma-Fe2O3 having >=25m<2>/g BET value. Dispersibility is good but there is an ill effect on a high frequency characteristic if the BET value is smaller than 20m<2>/g. The CrO2 alone is hardly dispersible if the BET value is >=20m<2>/g, but the substantial dispersibility is obtd. by decreasing the content thereof to about <=25wt%. The transmittivity of light decreases considerably and the need for using carbon black is eliminated and therefore, the electromagnetic characteristic is improved when the content thereof is specified to about >=5wt%.

Filed: 1989-10-20
Abstract: PURPOSE:To enable speed control which has favorable response even to a large-sized screw and is excellent even economically, by a method wherein a number of revolutions of an inverter motor is made to follow in accordance with an instruction value for an injection speed put out from an instructor, a difference between the instruction value and a practice value is operated by a comparator and the practice value is corrected by a servodriven motor through a differential mechanism. CONSTITUTION:A practice value (an injection speed put out by a large-sized invertor motor inferior in response in accordance with instructions shown by a broken line from an instructor 20 under a state where a rotation of a small-sized servomotor 1 is stopped) is drastically low as compared with an instruction value in the first speed filling stroke sphere. The difference is detected by a comparator 19 and instructions for speeding-up compensation is applied to the servomotor 1. The servomotor 1 decides a rotary direction and a number of revolutions by an arithmetic unit by receiving the instructions and transmitted to a differential gear train 14, 16, 16', 17 through a ring gear 15 and a rotary speed of a ball screw 2 is changed so as to approach the instruction value. Similar compensation to the first speed filling stroke sphere is performed even in the second speed to the fourth speed filling stroke spheres and highly accurate injection speed control to the same extent of the injection speed control with the small-size servomotor 1 is performed.
