Title: Automatic constant-speed traveling device
Inventor: KOBAYASHI IKUYA
IPC: B60W30/00
Filed: 1984-07-30
Abstract: PURPOSE:To prevent the automatic constant-speed travel control from being executed unwillingly due to an erroneous action of a computer or the like by inhibiting the execution of the automatic constant-speed travel when the shift lever of a speed changer is located at shift positions other than the first group indicating ''advance'' and when the car speed is low. CONSTITUTION:When a shift switch 12 is at either one of ''L'', ''2'', ''D'' positions of the first group, the transistor Tr105 of a switching drive circuit 10 is turned off via the detected signal SD of a detection circuit 13. At this time, if the car speed is a predetermined value or higher and the period of the output voltage V1 of a diode 101 is relatively short, the period of the output voltage V2 of HPF102 is also relatively shot, and Tr105 is turned off. Accordingly, the collector current flows through Tr107 via the output voltage V3 of an integration circuit 104, a relay switch 9 is turned on, and the constant-speed travel control can be performed via a control circuit 5. On the other hand, if the car speed is less than the predetermined value, the collector current of Tr107 is nearly zero, the relay switch 9 is turned off, and the control circuit 5 is made inoperative.

Title: Thermal sublimation printer
Inventor: MIYAMORI TAKAHISA
IPC: B41J17/36
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To detect the head or the end of a region of each color applied onto an ink ribbon in a thermal sublimation printer without using any special mark. SOLUTION: An ink ribbon sensor 50 comprising two sets of light emitting elements 51a, 52a and light receiving elements 51b, 52b is positioned on a same line orthogonal to the carrying direction of an ink ribbon 40 and yellow (Y) light is emitted from the first light emitting elements 51a while magenta (M) light is emitted from the second light emitting elements 52a. A part of light outputted from each light emitting element 51a, 52a is absorbed by ink applied to the ink ribbon 40 and since the color to be absorbed is different from color to color, the color of ink in a currently passing region is identified from the combination of output levels from two light receiving elements 51b, 52b. Furthermore, head and end of each region on the ink ribbon 40 are detected by detecting the moment of time when outputs from two light receiving elements are varied.

Title: Compressor
Inventor: MACHINO MINORU
IPC: F04B49/00
Filed: 1978-12-20
Abstract: PURPOSE: To increase the compressor discharge and heighten the pressure of the tank air when the tank air and the like is lowered by a mechanism wherein a displacement actuator which reciprocates in order to vary the cylinder clearance space is established within the clearance space of the compressor cylinder.  
     CONSTITUTION: Since the decrease of the pressure within an air tank causes to drcrease the air pressure in the discharge pipe 7, a discharge valve 12 is naturally opened under low air compression pressure of the compression chamber, allowing the motor to run under low rated output. Under this condition, this causes unbalanced condition between the compression force applied from the air tank and the compression force applied from a coil spring 19, which causes the sliding section 20a of the displacement section 10 to come out from the recess 18 into the cylinder 1. This allows to make small cylinder clearance volume in the cylinder 1 to decrease the residual air volume thereof, which increases the discharge volume to raise quiclky the pressure within the air tank.

IPC: G06F3/02
Filed: 1983-08-30
Abstract: PURPOSE:To inhibit the input given from a wrong input device by using an application program to designate an input enable input device to an operating system for each data input field. CONSTITUTION:An input request to an application program 1 is delivered to an operating system. Then a keyboard control program 2 decides an input device and delivers an input request only to an ID card reader control program 4. The program 4 controls an ID card reader 8 and sends the data input and a response back to a program 2 when the data input is through. The program 2 sends both the data and the response back to the program 1. Thus the data input is possible to an optional data input field from the program 1 and at the same time plural input devices can be freely designated. This inhibits an input given from a wrong input device.
