Title: Contour line data processing method
Inventor: KAMEI KATSUYUKI
IPC: G06T11/60
Filed: 1991-02-14
Abstract: PURPOSE:To suppress the difference of altitude between a triangular patch comprised of an obtained feature point and a contour line less than a prescribed value by deciding the allowable value of an allowable error in the decision of a feature point when the tangent approximation of the contour line is performed by making the allowable error proportionate to distance between the contour lines. CONSTITUTION:The position information of a line segment 18 connecting the start point of a fixed vector 2 while the contour line 1 is traced by a vector tracer to that of a continuous vector 4 is sent to a contour line interval measuring instrument 13. The contour line interval measuring instrument 13 finds distance wr, wl between the line segment 18 and the contour lines 8, 19 neighboring to the contour line 1, and sets the minimum value of the distance as a contour line interval (w). An allowable error decision device 14 finds the allowable error(e) of the tangent approximation of the contour line in (e)=kw and k=d/H by the contour line interval (w), the altitude difference H of the contour line, and the maximum value (d) of the difference of altitude between the triangular patch generated by the feature point on the contour line and the contour line. Thereby, it is possible to suppress the difference of altitude between the triangular patch and the contour line less than the constant value even when a gradient is steep.

Title: Diaphragm for speaker
Inventor: ISHII GIICHI
IPC: H04R7/02
Filed: 1983-02-10
Abstract: PURPOSE:To improve remarkably the articulation of reproduced sound by forming a diaphragm with a copolymer such as polypropylene and an inorganic filler and the rate of occupation by a minute hole on a surface layer is larger than that at an intermediate layer. CONSTITUTION:The surface layer 1a consists of the copolymer taking polypropylene or its major component, and the inorganic filler 12a of minute powder such as calcium carbonate, titanate or carbon black or flaky minute powder such as mica for the base 11a and the minute hole 13a are formed along the filler 12a. The intermediate layer 1b is the same as the base 11a, and the filler 12a is the same as the surface layer 1a, but the formation rate of theminute holes 13a is very smaller than that of the surface layer. Thus, the intermediate layer 1b forms mainly the factor for the Young's modulus, and the surface layer 1a contributes to the internal loss and the reduction in the stiffness at the coupling section of a coil bubbin. The articulation of the reproducing sound of a small sized speaker using the diaphragm in this way is improved remarkably.

Title: Motor-driven blower
Inventor: YAMAURA IZUMI
IPC: F04D29/44
Filed: 1985-02-06
Abstract: PURPOSE:To form an air stream in a smooth flow so as to prevent exfoliation and improve a silencing effect and efficiency, by forming between inner and outer guide walls a spaced part closing its end part while providing a communication part, which connects said spaced part with a return passage, in the inner and outer guide walls. CONSTITUTION:A blower sets between inner and outer guide walls 22, 23 a spaced part 25 closing its end part further forms a communication part 26, which connects the spaced part 25 with a return passage 20, in the inner and outer guide walls 22, 23. In this way, even if the outer guide wall 23 comes to easily generate exfoliation of an air stream, air is supplied from the spaced part 25 through the communication part 26. This supply of air, holding the air stream to be balanced, prevents exfoliation in the vicinity of the outer guide wall 23. The air is supplied from the communication part 26 of the inner guide wall 22, and the blower, smoothly supplying air along the inner guide wall 22 because the air is supplemented to the spaced part 25 from a communication hole 26 of the inner guide wall 22, improves also efficiency. While by the above constitution, the blower, serving in the spaced part 25 for silencing a noise with the communication part 26 being as an inlet, enables the noise to be reduced to a low level.

Filed: 1983-02-14
Abstract: PURPOSE:To reduce the amount of hardware of a terminal device by simplifying the transmission system between a terminal controller and the terminal device to miniaturize the terminal device and to control plural terminals by one terminal controller. CONSTITUTION:A data is transmitted always from simple terminals 1-8 and when the data is changed by the operation of a key switch, the data is included in a state change informing signal of one key and transmitted to a terminal controller 9. When the device 9 detects this signal, the data is fetched within a time interval of the key operation. As a result, the entire system is miniaturized without providing a buffer in the terminals 1-8 even if the number of sets of the terminals 1-8 is increased.

Title: Terminal device
Inventor: TOKURA MASUO
IPC: H04L29/12
Filed: 1981-02-18
Abstract: PURPOSE:To give the limitation or release to the use of a terminal device from a control station in an easy and quick way, by receiving a message of closing/ opening station which is previously decided from a public circuit and giving the limitation or release to the operation. CONSTITUTION:A message of closing station is sent to a circuit interface 10 of a terminal station A from a control station B via an exchange station C in the on-line mode. Thus a CPU1 discriminates the message as a station closing message. In such case, the data showing the closure of a terminal station is written in a prescribed area within a nonvolatile memory 4 to inhibit the subsequent working of a keyboard 8 and a print part 6. In case the inhibiting conditions is released, a station opening message is sent in the same way. Then the contents of the memory 4 is rewritten to the data showing the opening of the station. After this, the normal data processing is carried out.

Filed: 1990-01-31
Abstract: PURPOSE:To obtain an analog video signal suitable for driving a liquid crystal display device by providing a polarity inversion function and an adjustment means at an offset level and a full scale level at positive and negative polarity. CONSTITUTION:An offset level of n-channel red color signals R1-Rn is set by a set data at a positive offset level for an H period when no signal inversion is implemented at D/A converters 91-9n and set by a set data at a negative offset level for an H period when signal inversion is implemented. Then the offset level of a positive signal and a negative signal detected from the signals R1-Rn, a full scale level and a reference value are compared. As a result, the set data at a full scale level by the D/A converters 91-9n is adjusted and the set data of the offset level is adjusted. Thus, the signals R1-Rn obtained at output terminals 27R1-27Rn have an equal full scale level and offset level/and the deviation is automatically corrected.

IPC: F04B39/12
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the heating of intake refrigerant gas so as to improve volume efficiency by connecting an insertion pipe, inserted with a slight clearance into an intake muffler inlet port, to an intake pipe by an adhesive coil spring, and forming the insertion pipe of low heat conductive material such as stainless material. CONSTITUTION:Low-temperature low-pressure refrigerant gas returned from a refrigerating cycle is led into a compression element part 3 through an intake gas lead-in passage. The refrigerant gas turned into high-temperature high- pressure gas being compressed by the compression element part 3, is led into the refrigerating cycle through a discharge line 18 and a discharge pipe. Since an insertion pipe 15' is formed of low heat conductive material such as stainless material, the heating of the refrigerant gas can be lowered. The increase of the specific volume of the refrigerant gas flowing into a cylinder can be thereby prevented to improve volume efficiency.
