Title: Convergence optical system
Inventor: YAJIMA AKIHIKO
IPC: G02B19/00
Filed: 1989-01-24
Abstract: PURPOSE:To increase the convergence efficiency by composing the convergence optical system of a light source lamp, an elliptic lamp reflector whose front projection area is larger than lighting area, and a condenser lens. CONSTITUTION:The convergence optical system consists of the light source lamp 101, the elliptic lamp reflector 102 whose front projection area is larger than the lighting area, and the condenser lens 103. In this case, the large elliptic lamp reflector 102 is used to enable the light source 101 which is almost a spot light source to be used. In this case, light is converged and then diverged, so the condenser lens 103 is interposed to collimate the light. Consequently, the light source can be made into the spot light source, so the obtained parallel light has high parallelism and the lighting efficiency is improved.

Title: Led driving circuit
Inventor: AOKI KANJI
IPC: H01L33/00
Filed: 1989-01-24
Abstract: PURPOSE:To enable temperature characteristics of an LED printer head having a multibit LED to be corrected accurately by adapting the circuit such that temperature characteristics of output current are determined by temperature characteristics of a resistance and the printer head has uniform temperature characteristics in the whole head independently from an output bit. CONSTITUTION:When Vref is a voltage of a reference constant-voltage circuit, R is a resistance value of a resistance 7, beta3 is beta of a dummy transistor, beta4 is beta of an output transistor Tr, I3 is current of the dummy transistor and I4 is current of the output transistor, I3=Vref/R and I4=I3Xbeta4/beta3 or over. Accordingly, current I4 of the output transistor is represented by a voltage Vref, a resistance R and a current amplification ratio of the dummy and output transistors, beta4/beta3, and it is independent from variation of supply voltage. For temperature characteristics, a voltage Vref is related to a resistance R which is a physical constant and is constant independently from composition, temperature or the like. Temperature characteristics of Vref may be neglectable to a resistance R when difference in work functions used. Accordingly, output current is constant independently from a supply voltage and has constant temperature characteristics determined by temperature characteristics of the resistance R.

Title: Heat sensitive recording head
Inventor: ZAISHIYO MASAHIRO
IPC: B41J2/255
Filed: 1983-01-31
Abstract: PURPOSE:To make it possible to print a character or an oblique character having a different size, by respectively arranging a plurality of lines each comprising a plurality of heat generating elements arranged at predetermined pitches at angles different with respect to the moving direction of a head. CONSTITUTION:One of line driving terminals 1A-1E is selected corresponding to the inclination angle of an oblique character to be printed and voltage sufficient to generate heat from a heat generating resistor R is applied to the selected one through line driving wirings 3A-3E. At the same time, the selective voltage OV from a character pattern generator is applied to element driving terminals 21- 2n and a current is supplied to the heat generating resistor R through a diode D to print the oblique character. On the other hand, when a max. character is printed, the line driving terminal 1A is selected while, when a next smaller character is printed, the line driving terminal 1B is selected and the element driving terminals 21-2n are successively selected to perform printing. By this mechanism, the oblique characters or the characters having a different size can be printed without providing a separate heat sensitive head by a single character pattern generator.

Title: Picture processor
Inventor: TEZUKA SHIGEKI
IPC: H03M1/12
Filed: 1988-01-27
Abstract: PURPOSE:To output an accurate binary-coding signal even when luminous quantity radiated onto an object is fluctuated by calculating the difference of electric signals with respect to a picture outputted from a picture input means at every prescribed time interval and outputting the binary-coding signal based on the difference. CONSTITUTION:Picture input means 11, 12 convert the picture of an object into an electric signal, the level of the electric signal is stored in a storage means 13, and a difference calculation means 14 calculates a difference between the level of the electric signal outputted from the picture input means 11, 12 and the level of the electric signal before an optical time stored by the storage means 13. Then the difference is compared with a preset reference value by binarization signal output means 15, 16 to output a binarization signal. Since the binarization signal output means 15, 16 output a binarization signal when the rate of change in the electric signal is larger than the reference value, even if the luminous quantity radiated onto the object is fluctuated over a wide range, an accurate binarization signal is outputted.

Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain a program execution device which makes it easy to structure a decentralized system by interrupting the execution of a thread when a flag has a value indicating that movement is proceeding and performing a process for process movement when all threads in a process stop. SOLUTION: As information for managing the process 114, a process state flat 111, etc., representing the state of the process is prepared and managed by a process management part 101 and a thread management part 102. Respective threads which are being normally executed check the process state flag 111 periodically while executing program codes. If the process state flag 111 indicates 'movement is proceeding', each thread sets its own thread state to 'reported'. A thread which performs process movement considers that preparations for movement are completed when all the threads except itself enter a 'standby state', and starts the actual process-moving process.
