摘要:
In an air-fuel mixture supply device for an internal combustion engine, a butterfly-type throttle valve is disclosed whose upstream face is formed with a raised portion extending around the major of its periphery, but which is broken at least at the middle of the downstream part of the periphery of this upstream face. Thereby distribution of the air-fuel mixture is improved between the cylinders of a multi-cylinder engine.

A lighting device has a reflection sheet; an LED having an optical element arranged at a predetermined distant position away from the reflection sheet and being used for emitting light in a direction in parallel with a light emitting surface of the lighting device in a space between the reflection sheet and the optical element; and an optical sheet provided on the light emitting surface side of the optical element. A light shielding pattern is provided at a position corresponding to the LED on the light emitting surface side of the optical element, and the light shielding pattern is configured by stacking a plurality of light shielding layers in which the light shielding layer positioned closest to the optical element side is made of a white ink, and in which at least one of the other light shielding layers is made of a mixed color ink.

A data presentation apparatus having a function to generate a pointer image pointing a position in a presentation image is provided and includes: an image transmission section that transmits an image data of the presentation image to a terminal; a receiver that receives a control signal to determine a display position of the pointer image in the presentation image, the control signal being transmitted from the terminal; and an image generation section that generates an image data of a composite image based on the control signal, the composite image including the presentation image and the pointer image displayed in the presentation image.
摘要:
A current detection data is acquired by a scanning line current detection resistance, an adder-subtracter and an A/D converter. the current detection data is inputted to a voltage correction circuit, the voltage correction circuit output a correction signal. Using the correction signal, a scanning electrode voltage correction circuit performs the correction of the scanning selection voltage. Further, the voltage correction circuit generates data electrode drive data based on the current detection data and image data and inputs the data electrode drive data to a data electrode drive circuit. the present invention prevent a change of brightness and of smear with time.

A tool capable of easily producing a presentation content based on image exhibition is provided. The system allowed for making a presentation while taking an image of a material put on a material base of a material-presenting device by an imager device and projecting the image onto a screen. The real-time data of an image projected to the screen during presentation and the real-time data of a voice explanation are recorded, as presentation content data, in a content-producing device. The presentation is again reproduced as it is while reproducing the present-content data as primary data. On this occasion, by operating the material-presenting device in proper timing, the content is edited. By repeating the editing together with re-playing the presentation, a quality presentation content can be easily produced.
摘要:
To smoothly introduce intake air or mixture through at least one intake valve and exhaust combustion gas through at least exhaust valve, an intake side conical wall surface is formed in an inner wall of the cylinder head in smooth continuous connection with a conical surface formed at an end of the intake valve seat, and an exhaust side conical wall surface is also formed in the inner wall of the cylinder head in smooth continuous connection with a conical surface formed at an end surface of the exhaust valve seat. It is preferable not to allow liquid fuel introduced through the intake to flow directly toward an ignition plug provided at the center of the cylinder, but to allow the introduced liquid fuel to flow directly toward the exhaust port along a flat surface, recess, groove, guide surface, etc. formed around the ignition plug for prevention of misfiring. Further, it is preferable to form a recess on a top surface of the piston, project the ignition plug from inner surface of the cylinder head, incline ignition plug toward the exhaust port, obstruct liquid introduced through the intake valve by a boundary projection formed between the intake and exhaust side conical wall surfaces, etc.
摘要:
A cooling device for an internal combustion engine includes a communicating passage for communicating the inlet and outlet of a water pump, a cooling water temperature detecting means for detecting the temperature of cooling water for the engine and a valve controlled by the cooling water temperature detecting means for opening the communicating passage when the cooling water temperature is lower than a predetermined value and closing the passage when the temperature is higher than the value, so that when the engine is at a lower temperature the cooling water is not circulated through a cylinder block and a cylinder head of the engine, thereby rapidly raising the temperature of the engine to remarkably improve the exhaust gas characteristics and running performance and reduce the fuel consumption.
