Title: High speed rotary drive device
Inventor: GOTOU SHINJI
IPC: H02K7/09
Filed: 1984-06-21
Abstract: PURPOSE:To obtain a drive device which can rotate at a high speed with good rising by supporting a rotary member to the periphery of a stationary shaft, and providing driving means for driving the member displaced in a direction for reducing the contacting presure of the member to the support. CONSTITUTION:A cylindrical sleeve 3 is mounted through ultrafine gap E on the periphery of a columnar stationary shaft 21, a nondrive unit 7 is mounted, and supported onto the shaft 21 by a through bearing member 8. A magnet 5 is mounted on the periphery of the sleeve 3 to form driving means oppositely to a stator 4. In this case, the longitudinal central position of the stator 4 is displaced at a distance (d) in the direction of the member 8 with respect to the longitudinal central position of the magnet 5. Thus, when the stator 4 is energized, force of the direction for reducing the contacting pressure of the member 8 is operated to rotatably drive. Thus, stable high speed rotation can be rapidly obtained.

Title: Calorimeter for gas-flow adjusting type differential scanning
Inventor: MAIKERU RIIDEINGU
IPC: G01N25/20
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To condition the sample/reference of a differential scanning calorimeter(DSC) by regulating the characteristics of gas thermally touching the sample/reference of DSC. SOLUTION: Main heat flow passage between a sample/reference and a furnace passes purge gas from a furnace chamber 124 of a DSC cell. In order to condition the component of purge gas from furnace chamber 124, the DSC is purged alternately with high thermal conductivity gas (e.g. helium) and low thermal conductivity gas (e.g. nitrogen) thus regulating the heat flow to/from the cell. Temperature of gas flowing around the sample/reference is controlled to heat (cool) the sample/reference. The gas passes through the furnace before flowing around the sample/reference so that it is heated. Reference temperature of the sample/reference is regulated such that the ratio of gas flow for temperature control is regulated.  Furthermore, temperature of the temperature control gas is controlled and the regulation furnace having relatively low heat mass regulates the sample/reference at a relatively high ratio.

Title: Image forming device
Inventor: KUROTAKA SHIGEO
IPC: G03G15/00
Filed: 1991-05-31
Abstract: PURPOSE:To save power consumption and to improve operability by controlling starting and stopping actions of energizing the heat source of an image forming device by a signal from a controller. CONSTITUTION:A printing instructing signal is transmitted from a printer controller 2 based on the signal from a host computer 4. The paper feeding of a recording paper is started from a paper feeding device by the action of a driving part in a printer 1, at the same time, the heat source, for example, a heater in a fixing device is started to be energized. When printing actions of a specified number of papers are finished and a final recording paper is ejected outside the device, the signal informing the finish of the printing is transmitted to the controller 2 from the printer 1 and an instructing signal for stopping energizing the heater is transmitted to the printer 1 from the controller 2. Thus, power is supplied to the heat source such as the heater of the fixing device only when the printer is acting. Since an operator need not operate a switch when the energizing is started or stopped, the operability is improved.
