Title: Pin-type light receiving device, manufacture of the pin-type light receiving device and optoelectronic integrated circuit
Inventor: YANO HIROSHI
IPC: H01L27/144
Filed: 1994-03-02
Granted: 2003-09-02
Abstract: In a optoelectronic integrated circuit, a pin-type light receiving device and an electronic circuit device are electrically connected to each other and monolithically integrated on a semiconductor substrate.      In the pin-type light receiving device, an n-type semiconductor layer, an i-type semiconductor layer, and a p-type semiconductor layer are sequentially formed on the semiconductor substrate and sequentially formed into mesa shapes. The first mesa is constituted by the p-type semiconductor layer, and the second mesa is constituted by the i-type semiconductor layer. The boundary surface between the first and second mesas is formed to match the junction surface between the p-type semiconductor layer and the i-type semiconductor layer. The diameter of the first mesa is formed smaller than that of the second mesa.      With this structure, a depletion layer extending from the p-type semiconductor layer upon application of a reverse bias voltage stays within the i-type semiconductor layer and does not reach the surfaces of the first and second mesas to be exposed. For this reason, a dark current flowing in accordance with the interface state between the side surface of the mesa and an insulating layer for protecting the surface of the mesa is reduced.      Therefore, a noise signal input in the electronic circuit device is reduced to improve the receiving sensitivity.

Granted: 2000-05-23
Abstract: The present invention features a diagnostic method for assessing intermittent failures which occur in the components and systems of material handling vehicles.  The material handling vehicle of this invention uses an on-board microprocessor and display to allow an operator to determine whether any intermittency is present in the internal systems.  The microprocessor is programmed to analyze each system during normal vehicular operation.  The program is divided into two vehicular modes, "normal operating" and "program".  During the normal operating mode, the vehicle operator is warned of a problem by different audible tones and patterns.  A fault code scrolls across the vehicle display screen, indicating the nature of the failure.  The program mode can then be entered to assess just where the problem is located.  The program mode is divided into three additional modes: "maintenance mode", "configure mode" and "learn mode".  The vehicle is selected for maintenance diagnostics during the program mode, and then switched back to the normal operating mode, where the intermittent failures can be diagnosed.  The maintenance mode is divided into three diagnostic surveys: output controls, digital input measurements for analyzing switches and encoders, and analog input measurements for testing voltages and potentiometers.  Each system in the vehicle can be analyzed by selecting the proper maintenance code.

Title: Cleaning and finishing a ceramic mold
Inventor: SACHS EMANUEL M
IPC: B22C23/02
Filed: 1993-11-22
Granted: 2000-03-07
Abstract: A technique for removing loose powder (31) from the interior surfaces of a ceramic mold (17) made using layer manufacturing processes, such as three-dimensional printing processes. The interior of a mold (17) can be filled with water (21) which is boiled and the particles am entrained in the How caused by the boiling liquid. Alternatively, fine particles (51) are introduced into die mold (47) and agitated in the mold (47) to dislodge the particles (51) and the powder so that they can be poured out of the mold (47). Such technique tends also to remove the surface finish of the mold (47). Any of die particles (51) which remain can be dissolved in a liquid and removed in the liquid from the mold (47). Further, the surface finish of the mold (47) can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces.

Abstract: Process and device for tempering molding tools for processing plastics.     In convention tempering processes, it is not possible to adapt the temperature conditions to the instantaneous process parameters, and both quantities of interference in the injection molding process and the unfavorable position of cooling surfaces relative to the tool contour of complicated tools cannot be compensated.     As a solution, it is proposed that the tempering process is divided in two phases, a start-up phase and a stationary operating phase, each having different tempering conditions, whereby the start-up phase is completed after the preset nominal tool temperature has been reached or exceeded for the first time, and the meantool temperature is continuously measured during the entire cycle duration at a precisely defined site, and whereby at time Z2, the latter being fixed by a signal of the machine sequence control, a cooling medium impulse, the latter taking into account the tempering in the preceding cycles; is induced close in time to the injection process in order to effect the required heat dissipation within the time range of the greatest temperature difference between the injected melt and the cooling duct, and further cooling medium impulses are induced as the result of a should be-actual comparison occurring at time Z2 if the preset nominal temperature is exceeded, whereby the time Z2 is fixed by a signal of the machine sequence control, such signal being triggered at a defined time close in time to the end of the cycle.     The invention is preferably applied in the tempering of injection molding tools and leads to cycle time reductions of about 5 to 15%, a reduction of the reject quota by up to 35%, and to a reduction of the specific energy consumption by about 10 to 20%.

Abstract: In direct cooling an ingot emerging from a mold, two sets (136) and (142) of liquid coolant streams are discharged onto the ingot from an annulus circumposed about the lower end opening of the mold.

The two sets are staggered to one another circumferentially of the mold, and because of the high angle of incidence of the 45 degree set to the axis of the mold, substantial portions of the 45 degree streams rebound from the surface of the ingot at their points (144) of the impact with the ingot, and mushroom into corolla-like masses of air borne liquid coolant spray (146) lying crosswise the path of the 22.5 degree streams, which in turn entrain the spray and impact the successive layers (138) of coolant therebelow with the spray.
