Title: Digital-analog converting circuit
Inventor: YUGAWA AKIRA
IPC: H03M1/74
Filed: 1984-07-31
Abstract: PURPOSE:To obtain the same amplitude as that of a high voltage power supply with the use of a low voltage power supply and to eliminate invasion of noise from a power supply by constituting the titled circuit with two sets of capacitor arrays, a means increasing or decreasing a voltage of the other terminal of the arrays, a balanced operational amplifier and two sets of switches. CONSTITUTION:S3, S4 are closed at a period when reset is executed and a switch of the capacitor array A is thrown to the position of a reference voltage when the reference voltage VRef is higher than a ground voltage VGND. The switch of the array B is thrown to the position of ground. S1, S2 are connected respectively to the array A or B in response to the polarity of an input data. Thus, an offset voltage of the balanced operational amplifier is stored as a potential to contacts 1 and 2. In executing a D/A conversion, the S3, S4 are opened and the switch corresponding to the input data is changed over to a contact not for the contact used at the reset period. Then this voltage change decreases or increases respectively the potential of the contacts 1, 2. Since the input and output of the amplifier is tied with a capacitor having a capacitance of 16C, the output is changed for a voltage cancelling the said change.

Title: Image replay system
Inventor: SHIRATORI AKIRA
IPC: G09B29/10
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To reduce over looking of an image containing a picture of a mark point, which is a target for driving, when an image near a road of a running course is replayed. SOLUTION: A replay control part 4, from an image information storage part 2, reads such image information and position information as along a course specified by a course specifying part 8, and the image information is displayed on a display monitor 9. A mark point retrieving part 5 examines, based on the position information of the displayed image information, presence of a mark point information within a range corresponding to the image information in a map information of a map information storage part 1. If it is present, a replay speed setting part 7 decreases a replay speed. A mark point passage judging part 6 judges, based on the detection results of a steering angle detection part 11 and a current position detecting part 12, whether the car passes near a mark point.  If it has passed it, a fast-forward is executed to an image information corresponding to the car running point, and then the replay speed is restored to normal speed.

Title: Safety circuit for side clamp
Inventor: ARAI YASUHIRO
IPC: F15B11/08
Filed: 1977-12-27
Abstract: PURPOSE: To prevent clamping oil pressure from falling, by compensating the decrease in the clamping oil pressure by lifting oil pressure when the lifting oil pressure is higher than the clamping oil pressure.  
     CONSTITUTION: When the clamping oil pressure maintained by a first check valve is equal to a prescribed level at the end of clamping operation, a spool 22 remains moved left. At that time, a passage 23 for the lifting oil pressure is opened and this oil pressure is introduced into an equal pressure valve 26. When the clamping oil pressure is higher than the lifting oil pressure, the equal pressure valve is moved right and the clamping oil pressure introduced from a passage 28 is conducted to a branch pipe 20a through a passage 29 and drained to a move-down pipe 2. When the clamping oil pressure is lower than the lifting oil pressure, the equal pressure valve 26 is moved left to connect the passage 28 to the passage 23. Thereby, the lifting oil pressure is introduced into the clamping pipe 11. At that time, if the lifting oil pressure is higher than the prescribed level for the clamping oil pressure, the lifting oil pressure is reduced to the prescribed level by a maximum pressure control valve 33.
