IPC: G05D1/02
Filed: 1981-11-11
Abstract: PURPOSE:To perform automatic steering which follows up a scheduled route precisely by forecasting the external influencing power of a tide etc., at every scheduled point of time, and deciding on the speed of a ship to a next target point while considering the external influencing power. CONSTITUTION:A speed calculating device 6 uses scheduled sea course from a command device 1 and current position data from a navigation calculating device 5 to calculate a control speed. Namely, scheduled course data is read out of a memory 7 by an arithmetic device 10, and then ship position data of time written in a memory 9 one after another is read out. Further, it is stored in the memory 9 and arithmetic data on the last step is used to calculate external influencing force at a prescribed point of time, thus calculating the control speed. Then, the steering angle and engine revolving speed of the ship are calculated from the control speed and outputted as control commands to a steering device 2; and said processing is repeated.

Title: Pumping device using gravity
Inventor: YAJIMA KATSUJIRO
IPC: F04B53/12
Filed: 1989-07-12
Abstract: PURPOSE:To save the water lifting energy with a simple device to a great extent through utilization of the gravitational force by moving the liquid from below to above by the use of gravitation. CONSTITUTION:First the liquid in a device concerned is balanced with the gravitational force W. When a force is added to the gravitation W, devices 2, 3 will rise. At this time, a valve 5 shuts and a one 4 opens. From the chamber A the liquid passes water communication holes 6, 7 and moves to the chamber B. Removal of this additional force from the gravity W causes sinking till the time when the gravitational force W is balanced through the action of the gravity of the devices 2, 3 and the gravity of the liquid in the chambers A, C. When a force is added further, more sink is obtained than at the time of equilibrium. Also the speed is increased by adding an external force to the vertical motion. During sinking, the valve 4 is shut and the one 5 opened, and the liquid will flow to the outside.

Title: Transfer member separating device for image forming device
Inventor: KUZUMI TOORU
IPC: G03G15/14
Filed: 1989-07-14
Abstract: PURPOSE:To prevent the occurrence of an unusual electric discharge on the same polarity side as an electrification polarity of the photosensitive body while the destaticizing function of a separating electrifier is maintained by changing a duty ratio so as to decrease the peak value of a waveform with the same polarity as the electrification polarity of the photosensitive body. CONSTITUTION:For the photosensitive body 1, a positive electrification-type image carrier made of amorphous silicon is used, and a transfer electrifier 2 and the separating electrifier 7 are disposed. To impress a separating bias on the separating electrifier 7, a rectangular wave is outputted to the electrifier 7. An AC power source 3 which alters the duty ratio of the outputted wave, a DC bias power source 4 which controls a corona current, and a corona control circuit 5 which detects the corona current and controls it to reach the prescribed value, are connected to the electrifier 7. An area S1 is kept constant by decreasing a peak value V1 on a positive side and by changing the duty ratio t1/t2, and an area S2 is kept constant by increasing a peak value V2 on the negative side. Consequently, the positive and negative corona currents are maintained at constant levels. Thus, the occurrence of the unusual electric discharge is prevented.

Filed: 1980-12-19
Abstract: PURPOSE:To achieve a position detecting signal with good linearity, by writing four detection pulses with different phase toward circumferential direction into a servo track repetitively each 4 tracks and constituting a servo head with a specific width. CONSTITUTION:Position detecting pulses, Q1, Q2, E1 and E2 with different phase are written in each track from a track T1' to track T4' between clock pulse groups C1, C2, and the core width of a signal detecting servo head 20 is made wider than twice the servo track width Tw.

The difference between the Q1 pulse amplitude and the E1 pulse amplitude is a position error signal (solid lines) of the 1st phase, and similarly, the position error signal (dotted lines) of the 2nd phase is obtained, the phase of the position signal is shifted by one track width toward radial (X) direction mutually, the waveform pulse of zero points 1-4 at track boundary is selected and the 4-phase tracks are discriminated.

Filed: 1989-07-14
Abstract: PURPOSE:To allow each seam margin of two pieces of cloth to surely coincide at a needle set point even on any cloth having a variety of size and material by installing a control means which controls the first and second revolution shift means for turning the first and second supporting plates, independently according to the seam margin shape of each cloth to be seamed. CONSTITUTION:The first and second supporting plates 15A and 15B which support the upper and lower pieces of cloth W1 and W2 to be seamed are installed, and the first and second revolution shifting means A2 and B2 for revolution-shifting these supporting plates and the first and second rectilinear transfer means A1 and B1 for rectilinearly shifting the supporting plates in the transfer direction in synchronization with the transfer means are installed, and the first and second rotary transfer means are controlled independently along the seam margin shape of each cloth by a control means 21. Since the first and second supporting plates which perform instruction for the upper and lower pieces of cloth W1 and W2 shift in synchronization with the transport means such as feeding teeth, the cloth can be surely sent in the transport direction, even if the cloth to be seamed has a large dimension. Further, even in case of a curve having different seam margin shape of each clothe, each supporting plate revolution-shifts independently according to each seam margin shape, and the both seam margins can be allowed to coincide at a needle set point.

Filed: 1990-07-09
Abstract: PURPOSE:To encode an entire screen in the in-frame coding mode when a screen is changed by providing a frame memory to store an input frame and its preceding frame, an inter-frame difference calculation section and a moving vector detection section to the coder. CONSTITUTION:Frame memories 102, 106 store a screen of a current frame and its preceding frame inputted respectively from an input terminal 101 while divided into plural blocks. Then a moving vector detection section 107 detects the movement such as panning or zooming from the picture obtained through line 102b, 106a and outputs a picture of a preceding frame after movement compensation through a line 107a. An inter-frame difference calculation section 109 calculates a deference from a picture of a current frame and a preceding frame after movement compensation to discriminate whether or not a screen is changed over depending on the difference. Thus, when the screen is changed over, the entire frame is coded by using the in-frame code.

Filed: 1992-07-09
Abstract: PURPOSE:To increase the data transfer speed without reqiring any operation to the transmitted data in a data transfer system where the data are transferred between a control part consisting of a microcomputer and a peripheral device working under the control of the control part via a serial port. CONSTITUTION:A control part keeps the non-active state of a transfer control signal CNT for a period longer than the access cancel informing time T1 to inform all peripheral devices of the access cancel state. Then, the signal CNT is kept active for a prescribed access request informing time T2 so that an access request is reported. The signal CNT is set in a non-active state again with the access request. This non-active state is kept for a period shorter than the time T1 and equal to a period of duration that is set in response to the address of the peripheral device to which the data are transferred. Thus, this peripheral device, i.e., the data transfer destination is esignated. Then, the data are transferred to the designated peripheral device via a serial data line.
