Patent JP-H07271441-A (JP)
Title: Motor controller
Inventor: EBA KOJI
IPC: H02P29/00
Filed: 1994-03-28
Abstract: PURPOSE:To compensate for the omission of a command signal caused by a communication error with an extremely small low error in the motor controller for inputting the position or velocity command of a motor by communication. CONSTITUTION:When the communication error of a command signal PCMD(k) is occurred in k-th time, an alternate command arithmetic part 24 generates an alternate command signal TMPCMD(k). In a command cycle k+1 next to the generation of the communication error, a command correcting part 26 corrects the command signals in the past stored in buffers BUF1(2) AND BUF1(n) for acceleration/deceleration processing of an acceleration/deceleration processing part 14 based on the alternate command TMPCMD(k) and the separately retransmitted command signal PCMD(k) at the time of occurring communication error. In the (k+1)th command cycle, the acceleration/deceleration arithmetic part 14 executes acceleration/deceleration arithmetic based on the corrected command signals in the past and a command signal PCMD(k+1). Thus, even when any transient communication error is occurred, the exact control can be continued without stopping the motor, and the locus error due to a target position command can be minimized as well.

Title: Reflection optical system
Inventor: HIROSE TAKAMASA
IPC: G02B17/08
Filed: 1984-03-26
Abstract: PURPOSE:To widen the good image area of a corrected image height and to increase the printing quantity of a wafer per unit time by using a back-surface convex mirror and making at least either of the reflecting surface and refracting surface of the back-surface mirror aspherical. CONSTITUTION:Astigmatism and curvature of field are compensated by an aspherical lens L1. Consequently, the shape of the aspherical lens L1 is so deterimined that all of a main light beam parallel to the optical axis O of each image height in a compensation area (h) is incident on the center 02 of the convex mirror M2 and each main light beam reflected at the center 02 of the convex mirror M2 is all incident on an image plane is parallel. Consequently, the astigmatism is compensated and neither coma aberration nor distortion is caused because of the symmetry of the optical system, but when higher performance is required, chromatic aberration and other aberrations due to the glass thickness of the aspehrical lens L1 can not be disregarded. For the purpose, the convex mirror M2 uses the back-surface mirror and its surface is made aspherical to compensate chromatic aberration and lateral aberration due to the introduction of the aspherical lens L1.

Title: Air conditioner for automobile
Inventor: TOKI MASAYUKI
IPC: F24F13/20
Filed: 1981-04-20
Abstract: PURPOSE:To prevent moisture from gathering as drops on the outside surface of the casing of the evaporator of a refrigeration cycle and wetting the floor, by making the casing of an integrally molded resin body provided with hardened layers on the inside and outside and a heat insulation layer between the hardened layers and provided with drain flutes on the bottom of the inside. CONSTITUTION:When a refrigeration cycle is put in operation, the temperature of an evaporator 1 falls and the quantity of steam which can be present in the air in the evaporator decreases so that the steam gathers as drops on the surface and go down from the lower end of the evaporator to the bottom 2a of its casing. The water on the bottom 2a flows in drain flutes 2b integrally molded on the casing 2 and is discharged through a drain port. Since the casing 2 is a heat insulation body having internal air bubbles, the low temperature on its inside surface 2a is not transmitted to its outside surface 2d. For that reason, no moisture gathers as drops on the outside surface 2d.

Title: Method device for compressing and expanding picture, method/device for extending picture and storage medium
Inventor: ARAKAGE KAZUMI
IPC: H04N19/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for compressing and expanding a picture for obtaining character picture data to which quantization and a special effect are applied without preparing plural character picture data to which the special effect is applied before quantization. SOLUTION: A frame detector 11 detects a frame part from quarternarized data inputted from a quantizer 10, and prepares frame information. A central value changer 12 changes the picture element of an intermediate pixel code '11' into a pixel code '10', and changes the central value of the intermediate pixel code '10' to the mean value of the central values of the intermediate pixel code '10' and '11'. Also, a mixing ratio is changed in the same way. A frame preparer 13 changes the pixel code of the character data based on the frame information. Thus, a frame can be added to the periphery of the character of character data by this processing. The character data to which the frame is added by the frame preparer 13 are run-length encoded by a run- length coder 15, and outputted to an output terminal 6 as bit stream data.
