Filed: 1985-10-02
Abstract: PURPOSE:To prevent the blow-out of warm air by removing a fictitious temp. (constant temp.) of the outlet air temp., from the start of cooling until the outlet air temp. reaches a predetermined temp., and carrying out mode control using the detected value of said outlet air temp. CONSTITUTION:An outlet air temp. detecting means 9 detects the outlet air temp. of a cooling means 1. And, a control means 11 controls the cooling means 1 so that the outlet air temp. becomes a first predetermined temp. during the time when an operation indicating means 10 is indicating the operation of the cooling means 1. Also, while the operation of the cooling means 1 is being indicated, when a judging means 12 judged that the outlet air temp. is above a second predetermined temp., an output corresponding to a constant temp. from an outlet air temp. setting means 13, is selected through a selecting means 14, while on the other hand, when the outlet air temp. is judged to be less than the second predetermined temp., the output of the detecting means 9 is selected through the means 14. And, in line with this selected temp. and the opening of a mix damper means 3, a mode shifting damper means 15 is controlled through a mode control means 16.

Title: Heat-sensitive smell producing microcapsule
Inventor: SAKAI AKIRA
IPC: G01K11/00
Filed: 1992-08-18
Abstract: PURPOSE:To obtain a heat-sensitive smell producing microcapsule which can notify the temperature conditions even at a limited local point quickly and easily while selecting the temperature freely. CONSTITUTION:The heat-sensitive smell producing microcapsule encapsules admixture of a smelling substance 1 and a thermally fusible composition 2 with a shell 3. The thermally fusible composition 2 begins to fuse at a specific temperature. When the volatile smelling substance 1 is previously admixed with the thermally fusible composition 2, the thermally fusible composition 2 begins to fuse when the atmospheric temperature exceeds the specific temperature and the smelling substance 1 evaporates. Fusing temperature can be altered easily by altering the composition of the thermally fusible composition 2. The shell 3 suppresses the evaporation of the smelling substance 1 effectively and preserves the smelling substance 1 for a long term until fusion of the thermally fusible composition 2. This constitution restricts the evaporation of the smelling substance 1 in short time even upon fusion of the thermally fusible composition 2.

Abstract: PURPOSE:To control tape tension linearly even when the tension is small by fitting a magnetic plate to a reel base, fixing an electromagnet to a chassis, and flowing a detection signal current for the tape tension through an electromagnet coil to control the tension. CONSTITUTION:A high hysteresis plate 4 is projected annularly around a magnet friction evice, and the electromagnet M is fixed to the chassis 1 at the projection part opposite to magnetic poles (m) and (m). Said projection part is utilized for control operation. When the tension of a tape T is small, the amount of clockwise oscillation of a detection arm 12 increases to increase the isolation separation distance between a magnet piece 14 and a Hall element H, which outputs a small Hall voltage to obtain the difference voltage between a reference voltage and the Hall voltage. The difference voltage is amplified and supplied to the coil 11 of the electromagnet M to control attracting force to said projection part, controlling the tension to a necessary value. The tension even when increasing is controlled as mentioned above.
