Title: Air-fuel ratio control method for engine
Inventor: SATO NOBUHIKO
IPC: F02D41/14
Filed: 1985-08-14
Abstract: PURPOSE:To secure good acceleration performance, by continuing an operation at a theoretical air-fuel ratio for a preset time before the operation is shifted from a theoretical air-fuel ratio operation range to a thin air-fuel ratio operation range. CONSTITUTION:When a throttle valve 17 is opened in a state of idling in which a control valve 15 regulated to feed a mixture at a theretical air-fuel ratio, the control valve is driven on the basis of the output of an O2 sensor 22 to feed the mixture at the theoretical air-fuel ratio, in a theoretical air-fuel ratio operation range in which it is judged by a control unit 16 from the outputs of a pressure sensor 19 and a rotation speed sensor 20 that the intake negative pressure is not less than a prescribed value Po or the rotation speed is not more than a prescribed value No. When the operation is to be shifted, after the acceleration of an engine, from the theoretical air-fuel ratio operation range to a thin air-fuel ratio operation range in which it is judged that the intake negative pressure is not more than the value Po or the rotation speed is not less than the value No, the shifting is delayed for a preset time so that the operation at the theoretical air-fuel ratio is continued.

Title: Method and device for inspecting roughness on outer peripheral surface of glass vessel
Inventor: FUKUDA TOSHIAKI
IPC: G01B11/24
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To allow high-precision and rapid rough inspection on the outer peripheral surface of a glass vessel by projecting the image of vertical parallel lines on the outer peripheral surface of glass vessel, and judging a part of the image with wider interval between parallel lines to be a recessed part while a part with narrow one to be a protruding part. SOLUTION: An inspection signal is inputted with a glass vessel 1 set on a stage, and an image processing means clicks the shutter of an imaging means so that the picture of an image 2 of the outer peripheral surface of the glass vessel 1 is taken in for binarization. An image 2 of the slit is parallel when the outer peripheral surface of the glass vessel 1 has no rough, or normal case, while the image 2 is enlarged if a recessed part 13 is present and the interval of the image 2 of slit is enlarged. If a protruding part is present, the image 2 is reduced to narrower the interval of image 2 of the slit. The process is repeated until the glass vessel 1 is rotated once, and after one rotation, a maximum value and minimum value are selected from all measurement values, acquiring a difference.  When the difference is smaller than a pre-set tolerable value, the external peripheral surface of the glass vessel 1 is judged to be good, while it is judged to be defective if the difference is larger.

Title: Phs data communication equipment
Inventor: TAKAHASHI TOSHIHIKO
IPC: H04B7/26
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To perform high-speed data transfer with PHS data communication equipment by using a circuit element (LSI) for a low communication speed and, at the same time, to reduce the cost of the communication equipment by reducing the data errors in a transmission line, and perform high-quality data communication at a high speed. SOLUTION: When a radio communication control section 8 discriminates that two unused frequencies are required against a communication request, the section 8 selects different time slots at two different frequencies by controlling a channel CODEC section 4 and PLL section 7. When no unused frequency exists and, at the same time, an unused time slot exists at a used frequency and a different time slot combination exists at a difference frequency, the section 8 selects the different time slot at the different frequency. Then the section 8 performs data transmission (reception) at the transmitting-receiving timing of the time slot for transmission by controlling the PLL section 7 to operate at the selected frequency and CODEC section 4 to use the time slot for transmission.

Title: Optical memory device
Inventor: FUJI HIROSHI
IPC: G11B7/24079
Filed: 1988-07-20
Abstract: PURPOSE:To include many bits of information in one recording mark and to improve recording density in an optical information recording medium by causing the edge parts of first and second recording marks and the width of the second recording mark to correspond to the information. CONSTITUTION:For the first and second recording marks of an optical information recording medium 1, the edge part in a relative moving direction with an optical head 2 is correspondent to the second code of digital information and only when the edge part is irradiated with an optical beam projecting from the optical head 2, an information pulse is generated in a regenerative signal which is outputted from the optical head 2. For the second recording mark, a part between both edge parts is correspondent to the second code of the digital information. Then, the width of the second recording mark is formed to be narrower than that of the first recording mark so that the level of the regenerative signal can be made lower than a reference part when the part between both edge parts is irradiated with the optical beam. Thus, since many bits of information can be included in each recording mark, the recording density can be improved.

Title: Image area discrimination device
Inventor: HISAMURA TOSHIO
IPC: G06T7/00
Filed: 1994-07-08
Abstract: PURPOSE:To eliminate image deterioration by discriminating to which of a dot area, a character area and a photograph area a given picture element belongs and discriminating the area based on a density level difference and the number of dinary change points or the density level difference and a minimum density level especially when the given picture element is in a non-dot area. CONSTITUTION:A comparator circuit 7 threshold processes an image signal by using a calculated average density in a block as a threshold level and the result is stored in a register 8. The register 8 allows a change point detection circuit 9 to conduct the processing that the number of binary change points along with the main scanning direction is added to the number of main change points and the number of binary sub change points along with the sub scanning direction is added to the number of main change points. An area discrimination circuit 11 compares and discriminates the number of main change points with a threshold level of a 1st change point and the number of sub change points with a threshold level of a 2nd change point in the register 2. Furthermore, whether the given picture element is in a dot area or a non-dot area is discriminated so that mis-recognition of the dot area in spite of being in the character area or vice versa is avoided.
