Title: Sine wave pwm signal generator
Inventor: MORI MASATO
IPC: H03K7/08
Filed: 1989-01-23
Abstract: PURPOSE:To eliminate the need for a waveform generation data table on RAM and to alter an output voltage and a frequency at every carrier period by generating an interrupting processing at the specified point of a triangular wave carrier, computing an output change timing and permitting an output control means to output a PWM signal to the timing. CONSTITUTION:A computing means 101 generates the interruption processing in an uppermost point or a lowermost point or in both points in the triangular wave carrier, and computes the output change timing of respective phases from a next interruption generating timing to the subsequent interruption generating timing. The output control means 107 stores the output change timing of respective phases and outputs the timing at that time. Thus, the output change timing of respective phases can be generated without using the waveform generation data table on RAM and the output voltage and the output frequency can independently be changed at every carrier period.

Title: Color signal processing circuit for single board color camera using solid-state image pickup element
Inventor: SATO YASUSHI
IPC: H04N9/07
Filed: 1991-01-11
Abstract: PURPOSE:To suppress a false color signal generated near the Nyquist frequency when a horizontal high frequency signal component or a vertical high frequency signal component is received by providing a false color signal suppression control circuit. CONSTITUTION:Outputs Mg, Ye1, Ye2 and Cy are respectively led out from a solid-state image pickup element 1 with a color filter array 2 arranged thereto and fed to a brightness signal synthesis circuit 3 and a primary color separation circuit 4. Moreover, color signal outputs Ye1, Ye2 of two picture elements arranged in a mosaic are fed to a false color signal suppression control circuit 5. Then the control circuit 5 detects the horizontal high frequency signal component (center frequency is 1/2Px) and the vertical high frequency signal component (center frequency is 1/2Py) to control the color difference signal level in response to the signal levels. Thus, a false color signal generated when the horizontal high frequency signal component and the vertical high frequency signal component are received.

Title: Photoelectric element
Inventor: SHISHIDO YOSHIO
IPC: H01L31/02
Filed: 1982-01-29
Abstract: PURPOSE:To execute the detection of a focussed point and the measurement of of the distance of a subject with high accuracy by making the diameter or width of the photoelectric surface side smaller than the back side or forming the  photoelectric surface side to the same shape in the form of a through-hole for  detecting the focussed point. CONSTITUTION:The size of the diameter (or width) 22a of the through-hole 22 at the photoelectric surface 23 side is formed so as to be made approximately the same as the diameter (or width) of another projecting tip of a fiber 7 for illumination. In the photoelectric element 21 to which the through-hole 22 is formed, a circumferential wall surface at the front end of th through-hole 22 is thinly coated with an N layer 24 so that illuminating beams do not reach the photoelectric surface 23 (a P layer forming the surface 23) directly. Beams cannot reach to a photoelectric surface 2a because a through-hole 1 expanded (that is, the hole is expanded on the front surface side) on the hotoelectric surface 2a side is formed, but beams reach to the photoelectric surface 23 because the through-hole 22 is formed so as to be expanded on the back side. That is, the absence of the subject 10, which is displaced slightly from the focussed point to an imaging lens 9, at the focussed point can be detected.

Title: Fluorophosphate glass substantially free of bubble and production thereof
Inventor: KITAYAMA AKIMI
IPC: C03C4/12
Filed: 1979-02-09
Abstract: PURPOSE:To produce title glass having good transmission in a short-wave region, which is useful as a laser glass, by adding iodine and/or bromine at least in a specific amount, and melting and forming a fluorophosphate glass in an atmosphere of a neutral gas. CONSTITUTION:To a material for a fluorophosphate glass, such as P2O5, AlF3, BaF2, SrF2, CaF2, MgF2, NaF, MoO3, or Nd2O3, there are added iodine and/or bromine in an amount of at least 0.1 anionic percent, and the mixture is molten and formed in an atmosphere of a neutral gas, such as nitrogen. The formation of bubbles at the contact surface between the mixture and the platinum crucible can be mostly prevented, because the wetting of the mixture to the crucible is greatly reduced by the action of iodine and/or bromine. Consequently, good optical products with an extremely low bubble content can be obtained. Further, the melting in a neutral atmosphere reduces migration of Pt ions into the glass and so, the percent transmission of the glass in short-wave region is improved owing to the reduction in light absorption by Pt ions.

Abstract: PURPOSE: To obtain an inoculant having the effect of suppressing strongly the formation of the chill layer near the black skin surface of lead-contg. cast iron by mixing Mg, and Mischmetal to ordinary inoculants of Fe-Si type, graphite type, Ca-Si type, etc.  
     CONSTITUTION: An inoculant wherein 2W5% Mg and/or 5W50% Mischmetal by weight are contained in ordinary inoculants such as Fe-Si type, graphite type, Ca - Si type, Fe-Al type inoculants. Here, the Mg is usually an additive component for the purpose of formation of spheroidal graphite, and if it is large in amt., graphite spheroidization is accelerated and therefore it is added in the above- described range. The Mg and the Mischmetal can be added to ordinary inoculants respectively independently or simultaneously. Unless the lead-contg. cast iron to be added with this inoculant is of low content of S, the effect of preventing chilling does not appear distinctly. The inoculation with this inoculant is accomplished by charging beforehand a prescribed amt. of the inoculant, for example, to the bottom of a ladle, and putting molten metal in the ladle.

IPC: B41J2/175
Filed: 1992-01-30
Abstract: PURPOSE:To make it possible to control negative pressure with high accuracy by providing an atmospheric pressure communicating part which enables the movement of a movable wall due to the consumption of ink and placing gel-like substance non- compatible with ink in a boundary region between the inner surface of a container body and the movable wall. CONSTITUTION:A discharge port 3 for discharging ink is provided through a bottom plate of a container body 1 formed into a cylindrical shape and the port 3 is closed by a ball 5 which is always urged against the port 3 in a direction for closing the port by the resilience of a press spring 6. The open end of the body 1 is closed by a rear cover 3, in which a movable wall 4 is disposed so as to be movable in left and right directions. And a gel-like substance 7 which is insoluble in ink such as polybutane is placed between the inner wall of the body 1 and the wall 4. As ink is being consumed, the wall 4 is moved and resistance to the movement of the wall causes negative pressure of a recording head. However, since the ink non-compatible substance is present between the sliding surfaces of the wall 4 and the body 1, the wall 4 does not generate unnecessarily large negative pressure and hence the ink is supplied in a good state.
