Title: D/a converter
Inventor: IMAMURA MAKOTO
IPC: H03M1/74
Filed: 1991-03-28
Abstract: PURPOSE:To suppress the generation of offset by dividing a weighted constant current source into the two parts of a high-order bit and a low-order bit and supplying a prescribed bias voltage to the respective bits. CONSTITUTION:A weighted constant current source 1 is divided into the two groups of the group of transistors Q1-Q4 for high-order bit and the group of transistors Q5-Q8 for low-order bit. While considering the difference of the current density of a transistor for constant current source, a reference current source circuit 2a sets a base bias voltage for each group so as to hold a prescribed value (2:1) between outputs currents from the adjacent weighted constant current sources of the groups, and the set base bias voltage is supplied to the respective groups. Therefore, the offset generation caused by the difference in the current density of the transistor for constant current source is suppressed, and temperature drift can be suppressed.

Title: Slip printer
Inventor: OKAMURA YASUSHI
IPC: B41J29/22
Filed: 1981-07-07
Abstract: PURPOSE:To automatically stop printing after printing on the full area of a form paper while avoiding erroneous striking on a platen even at the time of erroneous feeding-in and printing of a small-size form paper, by a method wherein line counting is performed at the time of feeding in a slip form paper, and the region of the paper available for printing is detected and stored in a memory. CONSTITUTION:First, the slip form paper 7 is fed into a guide groove 19, and when this condition is detected by an upper-end detector 17, a CPU21 sends a starting signal for driving to a slip-driving circuit 22, whereby a driving shaft 9 is driven to draw in the paper 7. At this time, the paper 7 is passed through a gap of a lower-end detecting part 18, and a detection signal is outputted to the CPU21. Consequently, a counter provided in the CPU21 is reset and counts up the lines synchronously with the slip-driving circuit 22. Every time the printing of one line by a printing head 20 is completed, the counter in the CPU21 is caused to count down, and the circuit 22 is stopped when the count value coincides with a set point. EFFECT:The platen is prevented from being damaged.

Filed: 1982-06-22
Abstract: PURPOSE:To aim at obtaining higher brightness and securing a long life of an electron gun by specifically setting up the axial bearings of a cathode made of monocrystal LaB6 and forming its tip into a flat having the specific diameter. CONSTITUTION:The axial bearings 3 of a flat cathode of LaB6 are set up at (100) while its tip flat area 4 is formed into a flat having the diameter of 30- 100mum.
