Abstract: PURPOSE:To form diversified synthesis picture by providing an auxiliary device having a 1st memory, a picture generating means reading plural picture data from a 2nd memory and generating a picture signal and loading freely the auxiliary device to a main device removably. CONSTITUTION:A title data stored in a ROM 9 in an external storage section (auxiliary device) 8 is inputted to a control section 11 through a connection section 10 from the external storage section 8. The control section 11 sends the title data to a picture generating section 15 in response to the state of switches 12-14 and the picture generating section 15 writes the inputted data to a memory 16 and the data of the memory 16 is read by a command of the control section 11 to generate a title picture signal and a synthesis circuit 5 synthesizes it with the video signal. Since the connection section 10 is removable, the external storage section 8 is replaced with other type. Thus, even when the capacity of the memory 16 is comparatively small, diversified title or the like is displayed.

Title: Data reception equipment
Inventor: UESUGI MITSURU
IPC: H04B7/26
Filed: 1994-04-27
Abstract: PURPOSE:To realize data reception with a desired characteristic by providing the operation part of a selecting means, by which a user changes and adjusts various data reception characteristics, parameters of a demodulating means, etc., outside the equipment main body. CONSTITUTION:In the normal state, the user who uses the data reception equipment doesn't depress a high-quality mode changeover switch. For example, a first demodulating means 16 of low power consumption is selected in this case. If a long delay wave is received, the transmission quality is reduced to degrade the tone quality. When the user depresses the high-quality mode changeover switch, a second demodulating means 17 having a large compensation effect for the delay wave is selected to improve the tone quality. Thus, the user designates first to N-th selecting means 12 to 14 as desired, and optimum one of first to M-th demodulating means 16 to 18 is selected based on this designation by an adjuster 15, and its parameter is set.

IPC: F23N/
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To eliminate stop of a gas water heater when a het exchanger is clogged by obviating closing of a gas solenoid valve while flame current reduced by a lift of the flame temporarily generated after ignition is recovered to a predetermined value. SOLUTION: A holding current of a holding coil is not stopped even if a flame current becomes a decision value or less until a predetermined time T2 is elapsed from the time point of stopping an operation of an igniting circuit after the flame current arrives at the decision value so that the ignition is confirmed. Accordingly, in the case of igniting a main burner 20, a flow of combustion waste gas returned from a circulating tube 13 to a burner port 22 is abruptly increased, a lift occurs at the ignited flame, and the flame current is reduced to a predetermined value or lower as long as it is temporary after the ignition. Thus, even if the valve is closed, stop of the heater is not executed.  This predetermined time T is the time until the flame current reduced to the lift of the flame temporarily occurred after the ignition at the time of the degree that a blocking ratio is of the degree that it is not disturbed for use from confirmation of the ignition to the burner 20 is recovered to a predetermined value.

Title: Method for washing
Inventor: YAMADA YUTAKA
IPC: B08B3/02
Filed: 1986-04-18
Abstract: PURPOSE:To wash with facility and high efficiency a semiconductor wafer after scribing for which immersion washing may be accomplished only under certain restrictions and thereby to bring about improvement in the productivity and reliability in semiconductor devices by a method wherein a holder mounted with a semiconductor wafer is positioned under a cover and a washing liquid is allowed to flow toward the periphery between the cover and the wafer and the holder. CONSTITUTION:A holder 2 mounted with a wafer 1 provided with an adhesive tape 2a on its rear side and scribed as far as the rear side is placed under a Bernoulli's shade 4. Washing water is allowed to flow between the Bernoulli's shade 4 and the wafer 1 and holder 2 along stream lines 6 toward the periphery. The Bernoulli's shade 4 is gradually lower toward the periphery, which narrows the gap between the shade 4 and the wafer 1 and holder 2. This increases the speed of the washing water and, in line with Bernoulli's theorem, there is a decrease in pressure just above the wafer 1 and holder 2. The negative pressure sucks up power or tiny pieces of foreign substances and wash them away. Simultaneously, the wafer 1 and holder 2 themselves are sucked up.

Abstract: PURPOSE: To reduce forward voltage drop, by forming a wave-shaped pn junction.  
     CONSTITUTION: An n -  epitaxial layer 12 is provided on an n + -type Si substrate 11, and a wave-shape of several μm in depth is formed on the surface of the layer 12 by a photo-etching method and the like. Then, a p +  poly-Si layer 14 is epitaxially grown, and the surfaces are formed in the wave shape in consonance with the layer 12. Thereafter, a thin p layer 13 is formed by the diffusion from the p +  layer as a result of high-temperature treatment, thereby a wave-shaped pn junction 25 is obtained. The poly Si is transformed into a single crystal by the heat treatment. Then, Ni electrodes 14a and 11a are attached to the p +  layer 14 and the substrate 11, respectively. Since the pn junction 25 is in a wave shape, the junction area is increased, the current density is decreased, and the forward voltage is decreased.

Abstract: PURPOSE:To suppress the oscillations of a heater, etc. and to eliminate the increase a difference of control temperatures of the generated heat, by providing a positive feedback part which works for a fixed period of time from a time point when a heater is changed to OFF from ON and vice versa. CONSTITUTION:A temperature sensor 1 detects the temperature of a matter to be heated by a heater 7. A comparison part 4 compares a temperature signal detected by the sensor 1 with a reference signal. A microcomputer 9 uses said temperature signal to give the ON/OFF drive to the heater 7 through a drive part 6 so as to keep the temperature of the matter to be heated at a constant level. In this case, a positive feedback correction is applied to the temperature signal for a fixed period of time based on a timer function when the heater 7 is changed to OFF from ON and vice versa. Thus the oscillation of the heater 7 is suppressed. Then the positive feedback of a feedback part is released after a fixed period of time in response to the direction of inversion and at different time points.
