Patent JP-H03262656-A (JP)
Title: Device for thermal recording
Inventor: SASAKI MASANARI
IPC: B41J2/355
Filed: 1990-03-14
Abstract: PURPOSE:To record a multiplicity of gradation in good reproductivity and a half-tone image in a good condition by providing a power supply controlling means which is disposed correspondingly to each of a plurality of heating resistors and which controls the supply of power to the corresponding heating resistor only for a generation period of one pulse of pulse signals generated by a pulse signal generating means. CONSTITUTION:By varying energy to be applied to heating resistors 12-1 to 12-n, heating areas are varied as shown by, for example, 61a - 61c in the figure, and the sizes of picture dots are thereby modulated. In this case, when a supplied voltage is denoted as V, the resistance value of the heating resistors 12-1 to 12-n as R, and power supply time as T, the heating energy amount E of the heating resistors 12-1 to 12-n is represented by a formula of E = (V<2>/R)T, and the heating energy amount E is proportional to the power supply time T. Accordingly, by supplying power to the heating resistors 12-1 to 12-n having a substantially parallelogramatic shape for a period of power supply time only corresponding to the tone level of picture elements to be recorded, a half-tone image with high precision and high gradation can be recorded in a good condition.

Title: Current supply width control apparatus
Inventor: KOBAYASHI MASAYUKI
IPC: H02P7/29
Filed: 1988-03-15
Abstract: PURPOSE:To obtain the optimum pulse width in output power, by providing a means for controlling a switching (SW) element according to the current supply control pulse width determined on the basis of the ON-time of the SW element. CONSTITUTION:The title apparatus is adapted to the printing head driving part of a wire dot printer and printing head driving coils H1-9 are driven by a pulse like current made intermittent by transistors Q1-9. When either one of the coils H1-9 is in an ON-state, an input port P1 becomes low and, on the side of an MPU, it is detected that the transistors are in an ON-state. The MPU makes output ports P1-9 high (low) to make it possible to turn the transistors Q1-9 ON(OFF). Therefore, by measuring the time before the input port P1 becomes low after the output ports P1-9 are made low, an accumulation time tst is cleared. When a current is actually supplied to the heads H1-, the width of the high level outputted to the output ports P1-9 is adjusted with due regard to said accumulation time.

Filed: 1986-03-17
Abstract: PURPOSE:To set the best contrast of an interference signal by setting optionally the intensity ratio of two split light beams and arranging a wavelength plate which turns a direction of polarization by 90 deg. in an optical path. CONSTITUTION:When a laser generator 1 for linear polarized light is rotated, the direction of polarization of a beam also rotates, so the intensity ratio of object light 3 and reference light 4 split by a polarization beam splitter 14 is optionally settable without any energy loss. The direction of polarization of the object light 3 is parallel to the paper surface and that of the reference light 4 is perpendicular; and the direction of polarization of either one needs to be rotated by 90 deg. to cause interference. For the purpose, the 1/4-wavelength plate 15 is put in the optical path of the object light 3 and scattered light 9 is passed again to obtain linear polarized light which is rotated by 90 deg.. Thus, the scattered light 9 and reference light 4 has the same direction of polarization, so an interference signal is detected by a photodetector 12. Then the laser 1 is rotated and adjusted so that the scattered light 9 and reference light 4 becomes equal in intensity and then the contrast of the obtained interference signal becomes maximum.

Title: Soldering method
Inventor: AIDA HARUO
IPC: H05K3/40
Filed: 1988-03-15
Abstract: PURPOSE:To prevent the outflow of solder from a foot pad at the time of soldering by forming a slit or a through-hole at the specified position of the foot pad, shaping a recessed section and making excess solder flow into the recessed section on soldering. CONSTITUTION:A recessed section 6 is formed to a foot pad 2, to which spare solder 5A is executed, first, and a flat lead 4 to which preliminary soldering is executed is superposed and positioned. Infrared rays, laser beams or the like are applied as shown in the arrow L preliminary soldering is melted through heating, and the flat lead is soldered to the foot pad. Molten solder 5 flows into the recessed section shaped to the foot pad at that time.

Title: Projection type picture image display device
Inventor: ARIMOTO NOZOMI
IPC: H01J29/00
Filed: 1979-05-18
Abstract: PURPOSE: To enhance the utilization rate of luminuous flux and improve the aberrations at the peripheral part of the projection screen by interposing two kinds of light media between the light emitting surface and concave mirror of the projection type picture image display device which magnifies and projects television images, etc.  
     CONSTITUTION: The refractive index μ 2  of the light medium 25 between a reflecting mirror 27 and luminous flux exit face 29 is made larger than the refractive index μ 1  of a light medium 24. With such constitution, refractive effect is caused by the boundary face 30 so that the rays (a), (b), (c) are changed to (a'), (b'), (c') respectively and the ray (a') becomes less convergent than (a) and the ray (c') has a greater tendency to conversion than (c) but the ray (b) does not change so much with respect to (b). Hence, the aberrations at the periphery of the screen 22 may be considereably improved owing to the refraction effect at the above- mentioned boundary face 30 and if these refractive indices μ 1 , μ 2 , etc. are suitably adjusted, the image projection system of extremely less aberrations becomes feasible.

Abstract: PURPOSE: To prevent system interruptions in a system which performs information transmission between plural terminals, by controlling the supply of a back- up electric power to a terminal whose power supply is downed based on the operating condition of the other terminals at the time when the power supply to the terminals is downed.  
     CONSTITUTION: Plural terminals are connected in a form of a loop with an optical fiber 13 and controlling lines 14 and 15 of DC power supply. An interface circuit 1 receives a DC power supply from a signal processing section 7 through a power supply line 18 and a relay driving line 17, operates a transmission-reception module 16, and transmits signals to the processing section 7 through a signal line 19. When the power supply of the processing section 7 is not made, relays A and B do not operate, a contact (a) is disconnected, and a contact (b) is connected to a contact (c). In this case, when the other terminals operate, the electric power from the driving line 17 of the operating terminals closes the contact (a) by operating the relay A through the lines 14 and 15, and the module 16 is operated by connecting a back-up power source 20 to the module 16, and thus, interruptions of information transmission of the system are prevented.
