Abstract: PROBLEM TO BE SOLVED: To simultaneously dry and sterilize a kitchen knife by induction heating the kitchen knife housed in a waterdrop sticking state by controlling an inverter on the basis of detecting temperature information of a temperature detecting means for detecting an atmospheric temperature in a case by a control means. SOLUTION: A switching element performs switching operation by an ON signal from a control circuit 9, and an inverter 8 converts a frequency into a prescribed frequency to be supplied to a heating coil 7. The heating coil 7 generates a high frequency magnetic field according to a high frequency current. Since a kitchen knife 5 is composed of stainless steel or iron, the kitchen knife is inductively heated by interlinking the high frequency magnetic field. The kitchen knife 5 is dried by heating by this induction heating, and a waterdrop sticking to a surface quickly evaporates. Since a temperature detecting means 10 is arranged in a case 6, a rise in an atmospheric temperature by radiation heat from the kitchen knife 5 is detected so that this information is transmitted to the control circuit 9.

Title: Continuously variable transmission
Inventor: HANIBUCHI TAKAHISA
IPC: F16H3/74
Filed: 1985-05-09
Abstract: PURPOSE:To enable a transmission to both perform a continuously stepless speed change and increase its transmission torque, by dividing the output of an engine into two routes and connecting the both routes through a torque converter. CONSTITUTION:An output of an engine 1 is transmitted to an acceleration gear 2 by a gear 5. The acceleration gear 2, having subgears 6 in its plural axes facing the radial direction, transmits rotation in the mutually different direction to a transmission gear 4 and a driven gear 3 through said subgears 6. A transmission transmits rotation of the driven gear 3, reversely changing its direction by gears 9, 10, to an input shaft 14 of a torque converter 13 while rotation of the transmission gear 4, as being left in the same direction, to an output shaft 15 of the torque converter 13 through gears 12, 16, 11. A speed of the output shaft 15 can be continuously changed by changing speed change ratio of the torque converter 13, but the transmission, transmitting torque through the gears, enables the large transmission torque to be obtained.

Abstract: PROBLEM TO BE SOLVED: To increase absorption efficiency of light so as to improve sensitivity of light for controlling a high-frequency characteristic. SOLUTION: An In0.53 Ga0.47 As light absorbing layer 3, an In0.8 Ga0.2 As channel layer 4, and an In0.53 Ga0.48 As planer dope layer 7 are stacked on an InP substrate 1. The channel layer 4 is made of a material whose band gap is smaller than that of the planer dope layer 7, and an electron supplied from the planer dope layer 7 passes through the channel layer 4. The light absorbing layer 3 is placed so as to be adjacent to the channel layer 4. At least a part of lights L1 and L2 emitted from a surface reaches the light absorbing layer 3 so as to form an electrode and a hole. the lights L1 and L2 have smaller energy at which a light wavelength determines a bond gap. When the light reaches the light absorbing layer 3, an electron and a hole are formed in the light absorbing layer 3, and the electrode moves to the channel layer 4 so as to increase electrodes accumulated in the channel layer 4. Thus, a high-frequency characteristic is changed.
