Title: Ink jet recorder, recording head and method for driving same recording head
Inventor: TAMURA YASUYUKI
IPC: B41J2/05
Filed: 1990-01-12
Abstract: PURPOSE:To decrease electric current flowing through a drive circuit and control separately amounts of heat generation of electrothermal conversion elements by providing a selecting means for successively selecting each of a plurality of said elements and a pulse impressing means for applying electric pulses to the elements based on image data. CONSTITUTION:Each end of electrothermal conversion elements 1 is connected to an image data signal line 3. A counter circuit 2 successively outputs counter output signals Qo'' QN synchronously with a clock signal CK so that said signals are inputted to the base of transistors 5. The collector side of the transistor 5 is connected to the end of the element 1, while the emitter side thereof is connected to an electric power feed line 4. As a result, when signals corresponding to images to be recorded are given to the line 3 synchronously with a clock signal, electric pulses are successively applied to the elements 1 corresponding to the image data signals, whereby the elements 1 generate heat to deliver ink. And since the image data signals are introduced into the elements 1 not through a binary shift resistor, image data signal at each dot of image data can be applied as an analog value.

Filed: 1979-01-16
Abstract: PURPOSE:To maintain the temperature of a light source for original lighting constant by performing temperature controlling with a heat pipe with cooling fins provided in the lengthwise direction of a reflecting shade for light collection. CONSTITUTION:A heat pipe 1 mounted with disc-form fins 3 at the end part of a casing 2 is buried in part of the reflecting shade 5 of a halogen lamp 4 being a light source. The giving and receiving of heat of high efficiency are accomplished between the heat pipe 1 and reflecting shade 5. This makes it possible to maintain the temperature of the light source constant through natural heat radiation of the fins of the heat pipe 1 without using any cooling fan for preventing the temperature rise of the light source. If the fins are heated, the temperature may be readily elevated.
