Title: Air cooled absorption refrigerating machine
Inventor: TANAKA TAKAO
IPC: F25B15/00
Filed: 1988-04-05
Abstract: PURPOSE:To maintain refrigerant-absorbing performance of an absorber when the ambient temperature exceeds a set value by increasing the differential head of sealing fluid between a generator and the absorber to prevent a vapor refrigerant from flowing from the generator into the absorber. CONSTITUTION:When the detected temperature of an ambient temperature sensor exceeds 30 deg.C, a valve V is switched over from close to open by a controller C, and liquid absorbent flows into a branch line 49 and is stored in it until the differential head between the liquid levels in the branch line 49 and a generator 1 becomes equal to the differential pressure between the generator 1 and an absorber 4. As a result, sealing fluid between the generator 1 and the absorber 5 is maintained to prevent vapor refrigerant from escaping from the generator into the absorber 5, so that the performance of the refrigerant absorbing performance can be maintained. Therefore, a decrease in the operational efficiency with an increase in the ambient temperature is prevented. When the ambient temperature drops to the set value or less, the valve V is opened again by the controller C.

Title: Measuring method for melting point of gelatin gel
Inventor: KUWABARA RIKIYA
IPC: G01N25/04
Filed: 1988-04-07
Abstract: PURPOSE:To simplify an operation and to enable the execution of accurate measurement even when the quantity of gelatin is very small, by reading a temperature at the time when a colored liquid having a large specific gravity, which is positioned on a gelatin gel layer, falls down through the gelatin with the melting of a gel. CONSTITUTION:A gelatin sol of which the concentration of a solid part is 5-15wt.% is injected into a transparent slender tube ST of glass or the like the inside diameter of which is about 3-5mm and one end of which is closed, and then it is cooled down to congeal the sol into a gel. Next, a compound of sugar such as cane sugar is dissolved therein so as to set the specific gravity at about 1.1-1.5, and a colored solution is injected into the tube ST by means of an injector or the like so as not to cause air bubbles and is made to be positioned on a gel layer. This tube ST being set in a water bath 14, the temperature of water is raised at a rate of 1 deg.C/min. by a heater 101. On the occasion, temperatures at the moment when the colored solution wherein the gel is melted falls toward the lower side of the tube ST and at the moment when it falls down rapidly are read by a thermometer 141, and thereby a melting point can be measured as a value having a temperature width. In this way, it is possible to decrease a fluctuation coefficient and to reduce the nonuniformity in measured values.

Title: Driving method for optical modulating element
Inventor: OKADA SHINJIRO
IPC: G02F1/133
Filed: 1985-04-22
Abstract: PURPOSE:To shorten a write time by clamping an optical modulating element with a scanning line and a signal line and constituting a matrix picture element structure, and writing information in matrix picture elements by driving only a scanning line. CONSTITUTION:A ferroelectric material which has the 1st and the 2nd optically stable states is made into liquid crystal as the optical modulating element. This optical modulating element is clamped with signal lines 7 and scanning lines 8 to constitute the matrix picture element structure. For example, one character consists of 8X8 picture elements and 'd' in a character area A22 in figure (a) is converted into 'D' as shown in figure (b). In this case, an erasure signal is supplied to scanning lines S9-S16 and signal lines I9-I16 in figure (a) to let the area A22 'white' and selection pulses are supplied successively to the scanning lines S9-S16 in figure (b) to display information of the signal lines I9-I16 successively, thereby rewriting the character 'd' into 'D'. Thus, the optical modulating element which has a fast response speed is used and scanning lines where picture elements to be rewritten are present are driven, so the write time is shortened and the driving electric power is saved.

Title: Information reader
Inventor: AKIYAMA TOORU
IPC: G11B7/08
Filed: 1982-05-19
Abstract: PURPOSE:To decrease the returning time of an actuator, by opening a servo loop when an amount of deflection of the actuator exceeds a prescribed range, and controlling the amount of deflection of the actuator to the initial value with a signal in response to the amount of deflection. CONSTITUTION:While the tracking servo loop is turned on at the scanning operation, the deflecting angle of a mirror 10 is increased gradually. Thus, the center position of reflecting light of a photodetector 2 is shifted in the orthogonal direction to the track gradually. Then, since an output of a subtractor 18 changes to positive or negative accordingly, this subtraction output represents the amount of delection of the mirror 10. Since this signal is applied to a coil 11 when the tracking sevo loop is opened, a new servo loop which makes this signal zero is formed, resulting in the returning of the mirror 10 to the initial position, i.e., the rotating neutral point rapidly.

Title: Magnetic recording medium and magnetic recording and reproducing method using said medium
Inventor: KITAMOTO TATSUJI
IPC: G11B5/00
Filed: 1987-04-08
Abstract: PURPOSE:To decrease spurious components and to improve the signal to noise ratio of color signals by using a magnetic recording medium formed by constituting magnetic materials having different reproduction output characteristics to temp. into two layers. CONSTITUTION:A magnetic recording layer contg. a barium ferrite magnetic material in the upper layer and the magnetic recording layer contg. a magnetic material consisting of chromium dioxide or Co-modified iron oxide alone or mixture composed thereof in the lower layer are provided on a base. The magnetic material to be used for the lower layer is preferably Co-FeOx and CrO2 which are reverse in the characteristic of a change in coercive force with temp. from Ba ferrite and further, CrO2 having a large difference in a change in magnetization with temp. Since the magnetic recording layer is constituted in the double layers in such a manner, recording of an F1 component in the lower layer and an f2 component in the upper layer is possible if the f1 component of the low frequency range is recorded by a 1st head and in succession the f2 component of the higher frequency range is recorded by a 2nd head. Since the f1 component is decreased by medium heating at the time of reproduction, the spurious components to be incorporated into the f2 component decrease as well. The recording level of the f2 component is thereby increased further and the SN of the reproduced f1 component is improved.
