IPC: F24F11/02
Filed: 1990-10-08
Abstract: PURPOSE:To enable a temperature to be rapidly set to a target temperature feeling by a method wherein a future temperature feeling is estimated on the basis of a skin temperature of an occupant in a period ranging from the past to the present time and then an air conditioning control is carried out. CONSTITUTION:A skin temperature of an occupant got through an infra-red ray thermometer acting as a temperature feeling information sensing means 1 is inputted to a temperature feeling estimating means 2. As this input, the present skin temperature and some skin temperatures measured for every 30 seconds before 1 minute and 30 seconds are applied and then a temperature feeling after one minute is estimated with a neural network (a temperature feeling estimating means 2). Then, the estimated temperature feeling and the stored temperature feeling stored by a control pattern memory means 3 at the same time as that of the estimated temperature are compared to each other by a controlling amount determining means 4 to get their deviation. In the event that the estimated temperature feeling is displaced toward a colder temperature, the heating intensity during a heating season is increased and then a cooling capability during a cooling season is decreased to cause such a controlling amount to be transmitted to an air conditioning means 5. However, a control for 30 seconds after starting the air conditioning operation is carried out to keep a room temperature of 25 deg.C and this temperature feeling estimating means is utilized after 30 seconds of starting of the air conditioning operation and then the controlling operation is carried out.

Title: Optical writing head
Inventor: YAGI KEIICHI
IPC: B41J2/44
Filed: 1988-10-27
Abstract: PURPOSE:To absorb the difference between the expansions of an optical writing head and a supporting plate and thereby make possible the reproduction of an output image without distortion by holding the main unit of the optical writing head between the supporting plate with high rigidity which comes in contact with a glass substrate and a cover member. CONSTITUTION:The main unit M of an optical writing head is held between a supporting plate 1 with high rigidity which comes in contact with a glass substrate 4a and a cover member 8. If the supporting plate 1 and the main unit M of the optical writing head are heated with heat generated during use of the optical writing head H, the difference generates between the thermal expansions of the supporting plate 1 and the main unit M of the optical writing head because the coefficients of thermal expansion of the supporting plate 1 and the main unit M of the optical writing head differ. However, this difference between the thermal expansions is eliminated by sliding the glass substrate 4a of a hermetically sealed case 4 on the supporting plate 1. Subsequently, no flexion generates in the supporting plate 1 and the main unit M of the optical writing head due to a bimetal effect resulting from the difference between the coefficients of thermal expansion.
