Title: High speed switching rectifier
IPC: H01L27/06
Filed: 1969-03-12
Abstract: A semi-conductor structure is equivalent to a PN diode and a four layer diode connected in parallel, the breakover voltage of the four layer diode being less than the breakdown voltage of the PN diode. The device has a normal diode characteristic in the forward direction and a breakover type characteristic in the reverse direction. As shown, Fig. 4, a four layer diode with its outer junctions shorted by the electrodes 136, 138 effectively comprises a four layer diode 112 (within the dotted lines) surrounded by a PN junction diode 114 which provides the normal diode type characteristic in the forward direction. When biased in the reverse direction the four layer diode breaksover into conduction by the avalanche effect, while in an alternative embodiment, Fig. 6 (not shown) conduction of the four layer diode is initiated by punchthrough current multiplication. The lower electrode 138 may be replaced by separate ohmic contacts (140, 142) to the P region 118 and the N region 122 connected together by a plate (144), Fig. 5 (not shown). More than one four layer portion may be included in the same body effectively connected in parallel to each other and to the diode, Fig. 6 (not shown).

Title: Automatic exposure time control device for cameras
IPC: G03B7/083
Filed: 1970-02-25
Abstract: An improved automatic exposure time control device for cameras is composed of mechanical and electronical parts. A means is provided for converting the brightness of the object to be photographed into the control current including a photosensitive element and a capacitor wherein a differential amplifier is integrated, one input of said amplifier is subjected to a voltage proportional to logarithm of the brightness of the object and the other is subjected to a voltage in response to the exposure factors. Further an indicator is connected between said input terminals and another manually adjustable resistor is provided for manual control. The control current which sets exposure time is compensated for automatically by the circuit including the differential amplifier and the indicator with regard to the characteristics of the photosensitive element. When the mechanism is switched to manual control the measuring circuit having the indicator also acts as the interlocked exposure meter, and the exposure time may selectively coincide with either the indicated optimum value or the arbitrary deviated under-or over-exposure value.

Title: Method for the cooling of solid residues of gasification
IPC: C10J3/52
Filed: 1980-07-31
Abstract: The present specification describes and claims a method and apparatus for use in cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials. The residue of gasification is conducted out of the reactor into a cooling apparatus located therebelow and flows through the cooling apparatus from the top to the bottom thereof. A cooling liquid is introduced into the solid residue in the upper region of the cooling apparatus and is metered such that the greater portion of the heat contained in the residue is eliminated in the form of heat of vaporization, sensible heat and chemical binding energy with the resultant steam and reaction products produced. The remaining residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchange.

Title: Integrated semiconductor memory matrix using one-FET cells.
IPC: H01L21/8246
Filed: 1981-01-05
Abstract: A storage system, such as a read only memory, is provided which includes field effect transistors each having first and second spaced apart diffusion regions of a given conductivity and a gate electrode, with at least one of the two diffusion regions of selected transistors having a third diffusion adjacent to one of the first and second diffusion regions under the gate electrodes to provide a higher voltage threshold for the gate electrode to one diffusion than for the gate electrode to the other of the two diffusions. A voltage is applied to the first diffusion having a polarity and magnitude sufficient to neutralize or eliminate the effects of the higher threshold during a first time period and the current flowing between the first and second diffusions is sensed. During a second period of time the voltage is applied to the second diffusion and the current flow between the first and second diffusions is again sensed. In this manner two cells or bits of information are stored in each transistor, one at the first diffusion and one at the second diffusion. Multilevel storing may also be employed by establishing one of more than two predetermined voltage thresholds at each of the first and second diffusions.
