Title: Reproducing system using magnetic tape
Inventor: SHIMIZU NORIYOSHI
IPC: G11B5/008
Filed: 1988-08-15
Abstract: PURPOSE:To effectively use a buffer RAM by detecting the number of data in individual recording areas at the time of reproducing while traveling a magnetic tape in the reverse traveling direction of its normal traveling direction, calculating the sum total of the detected number and stopping the reverse traveling of the magnetic tape when the sum total is in excess of a storage capacity of a storage means and then performing the reproducing operation. CONSTITUTION:When the magnetic tape 1 is reproduced while being traveled in the reverse traveling direction of its normal traveling direction, the data recorded in control data recording parts SD1-SDn in the individual recording areas, or more in detail, the number of data recorded in main data recording parts MD1-MDn are detected in turn to calculate the sum total. Then, when the sum total is in excess of the storage capacity of the storage means, the traveling of the magnetic tape 1 in the reverse direction is stopped, and from this point the reproducing operation is started by making the magnetic tape 1 travel in the normal direction, while the reproduced data are stored in the storage means. By this method, the buffer RAM 30 is effectively usable, and even when the buffer RAM 30 is of a small capacity, the reverse reproducing can smoothly be performed.

Filed: 1983-10-27
Abstract: PURPOSE:To maintain the heating calory without lowering the quantity of a heat medium flowing to a condenser even when the temperature of external air is low by providing a controller which flows a heat medium liquefied by a condenser from a liquid receiver to a heater and a flowpath which reduces the pressure of the liquid, and also providing a flowpath which introduces the liquid under a reduced pressure from the bottom part of the heater to a compressor. CONSTITUTION:Steam of the heat medium is generated by the heater 12, and is introduced into the condenser 2 through an outlet flowpath 6 and a part of a heating main circulating path so as to appropriately maintain the flow quantity of the heat medium within the condenser 2. Upon this occasion, the supplement of a flow quantity 16 of the heat medium to the heater 12 is intermittently carried out from the liquid receiver 11 by a controller 20. With the circulation of the heat medium, oil within a compressor 1 melts into the heat medium, and circulates and gradually accumulates at the bottom part of the heater 12. In this case, the bottom part of the heater 12 is pressure-reduced through a throttle part 104 by a flowpath 103, and the heat medium circulates to the compressor 1. Thus, deficiency in oil within the compressor 1 is prevented.

Title: Manufacture of speaker diaphragm
Inventor: BABA FUMIAKI
IPC: C08K7/02
Filed: 1986-08-29
Abstract: PURPOSE:To provide a high specific elastic ratio and a proper internal loss to a diaphragm by forming a diaphragm including >=10wt% thermoplastic liquid crystal polymer and 3-40% fibrous filler. CONSTITUTION:In injecting a speaker diaphragm material including >=10wt% liquid crystal polymer and 3-40wt% filler into a molding die in the molten state, the flow of the polymer is a diffusion flow and molded pieces oriented largely in the direction of the arrow B are obtained. Thus, the fibrous filler is mixed in the polymer, then the fibrous filler makes the polymer orientation at molding uniform. The specific elastic rate of the diaphragm is higher than that obtained without using the fibrous filler. Since the orientation of polymer is more stable and uniform than that of the diaphragm, stable molding is attained.

Title: Method for measuring shape of material body
Inventor: SAIJO TERUAKI
IPC: G01B17/00
Filed: 1988-08-16
Abstract: PURPOSE:To accurately measure the shape of a material body under water with no contact by turning an ultrasonic transducer around the center of an ultrasonic wave emission surface of the transducer while detecting the intensity of a reflected wave on the surface of a material body to be measured. CONSTITUTION:The ultrasonic transducer(TD) 1 is moved at every specified angle on a circular arc 5 positioned in an equal distance from the center of rotation O. By setting the moving position as each measuring point, the position of the TD 1 on each measuring point on the circular arc 5 can be uniquely decided. Since the position of a turning angle concerning the center of the ultrasonic wave emission surface of the TD 1 is known, the direction of the ultrasonic wave emitted from the TD 1 is also decided. Therefore, if the surface reflected wave of an ultrasonic pulse emitted from the TD 1 positioned thus is detected, the reflected position thereof can be specified and the coordinate of the surface position of the material body 3 to be measured can be obtained. As a result, the shape of the material body to be measured can be measured based on the coordinate of the surface position of the material body obtained on each measuring point by moving the TD 1 along the circular arc 5 and obtaining the coordinate of the material body at the positions of each measuring point.

Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions due to the irregularly reflected light by shielding the light irregularly reflected at the inner surface of upper/lower half cases constituting a magnetic tape cassette or at a tape reel, before entering into light transmission holes. SOLUTION: Light shielding walls 41 are provided with wall parts 41a, 41b different in height from the inner surfaces of the upper/lower half cases 2 near the light source side of the light transmission holes 48 formed in the upper/lower half cases 2, then the straight-advancing light (a) projected from the light source L is passed through the light transmission holes 48 and is received by an optical sensor S.
