Title: Air conditioner for vehicle
Inventor: KAWAI NOBUYUKI
IPC: B60H1/32
Filed: 1990-09-20
Abstract: PURPOSE:To prevent an unpleasant feeling due to the fact that blowoff temperature is high by enabling an air volume controlling means to control a driving means to reduce the air volume of a blower fan more than normal in response to the inhalation temperature when the temperature inside a car room is below the specified temperature and the inhalation temperature exceeds a specified value. CONSTITUTION:When the indoor temperature TINC is below 30 deg.C, the inhalation temperature TINT is judged whether it is not more than 15 deg.C or not. When negatively judged, namely, the inhalation temperature exceeds a specified value, impressed voltage Vf'' is determined by a formula of Vf''=Vf'-(TINT-15)...(1). Then, the impressed voltage Vf''is impressed to a blower fan motor 9a through a blower fan control circuit 65 to drive a blower fan at a speed responding to that voltage Vf''. On the other hand, when the temperature inside a car room is below 30 deg.C and the inhalation temperature exceeds 15 deg.C, the impressed voltage Vf'' is determined by the formula. If this formula is observed, the higher the inhalation temperature TINT is, the more the impressed voltage Tf'' is lowered reducing air volume of the blower fan.

Title: Color picture information processing method
Inventor: ISHIDA AKIRA
IPC: H04N1/46
Filed: 1990-09-20
Abstract: PURPOSE:To improve gradation reproducibility and picture quality by dividing error between an input signal and a threshold, which is generated when the input signal from an input picture element is binarized by the threshold, at a specified ratio and accumulatively adding the divided result to the input signal from the following picture elements after the next one. CONSTITUTION:The density value of an input picture element 7 of a color picture 4 or an objective value adding an error added part to the density value is binarized by comparison with the threshold value T. The difference between the objective value and the threshold T is divided into the error added part in a size proportional to a coefficient in the partial matrix of a coefficient matrix 2 equipped with periodicity in a one-dimensional or two-dimensional direction composed of elements fixedly corresponding to the position of the input picture element 7, and added to the objective value of the other input picture element distributed fixedly corresponding to the position of the input picture element 7. Thus, the processed picture can be obtained with faithful gradation reproducibility and satisfactory picture quality.

IPC: G11B7/135
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To contrive a high density recording and to prevent a loss in crosstalk characteristic by making the track pitch of a recording track almost equal to the spot radius of a first area. SOLUTION: The track pitch Tp to be determined by widths of a land part 3 and a guiding groove 4 is made almost equal to the distance from the intensity center of the beam spot 6 of the light beam on a light irradiation surface to a position where the intensity of the spot becomes minimum first. In an optical recording medium in which A (the effective radius of an objective lens/W (the spot size of a light beam)) is set to <=1.0 by designing the track pitch Tp in such a manner, when a prescribed recording track is irradiated with the light beam, a position where the intensity of the light beam is minimum is made to be positioned at almost the center of an adjacent track. Consequently, the crosstalk from the adjacent track becomes minute naturally and the high density recording in the arrangement direction of tracks is attained.
