Title: Method and apparatus for manufacturing semiconductor device
Inventor: INOUE HAJIME
IPC: H01L21/52
Filed: 1990-09-10
Abstract: PURPOSE:To keep the continuity of the electric characteristic of semiconductor pellets even when an arbitrary lead frame falls off by a method wherein, when the semiconductor pellets divided from a semiconductor wafer are pellet-bonded to a lead frame, they are pellet-bonded in such a way that the electric characteristic of the semiconductor pellets between both lead frames in a relationship between the front and the rear with reference to the arbitrary lead frame is continued. CONSTITUTION:Semiconductor pellets 8 divided from a semiconductor wafer 2 are taken up based on a taking-up sequence; they are pellet-bonded to prescribed positions on a lead frame 6. In this case, the semiconductor pellets 8 on the semiconductor wafer 2 are taken up in a zigzag shape at a stroke which is half the quantity of the semiconductor pellets 8 bonded inside one lead frame 6. In this manner, all the semiconductor pellets 8 on one semiconductor wafer 2 are mounted on the lead frame 6. Consequently, even when an arbitrary lead frame 6 falls off, the number of semiconductor pellets 8 which fall off on lead frames 6 of the lead frame which has falen off in the front and the rear can be reduced to only two on the semiconductor wafer 2.

Title: Method and device for starting electrodeless discharge lamp
Inventor: SCHULTZ WILLIAM NEWELL
IPC: H05B41/24
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To obviate manual operation of a start-up circuit and removal after start-up by preparing a tuning type start-up circuit containing start-up inductance and start-up capacitance, starting start-up plasma by exciting a high frequency ballast, and detuning the start-up circuit by using a mechanical detuner. SOLUTION: A starter contains a movable conductive element 50, and this is composed of a conductive plate. When starting a discharge lamp, the conductive element 50 is positioned at a sufficient distance from a parallel IC cuircuit so that a small electric current (i) generates sufficiently large voltage (v) for starting plasma. When the starting plasma is once started, a solenoid or the other mechanical actuator 52 sufficiently brings the conductive element 50 near to a starting inductor to detune a starting circuit to thereby effectively remove the start-up circuit from a ballast. Thus, the start-up plasma vanishes, and a casing of the discharge lamp is protected from corrosion by the start-up plasma.

Title: Antilock brake device
Inventor: OTSU NOBUYUKI
IPC: B60T8/72
Filed: 1992-09-07
Abstract: PURPOSE:To shorten the brake distance, securing the stability of a vehicle, by control ling the brake hydraulic pressure of a rear wheel cylinder on the basis of the brake hydraulic pressure decompression threshold value of the wheel cylinder which corresponds at a prescribed rate of the pseudo car body speed and the rear wheel speed selected by a rear wheel speed selecting means. CONSTITUTION:The pseudo car body speed is calculated on the basis of the max. wheel speed calculated by each wheel speed sensor, and the rear wheel speed selecting processing is carried out. Then, the calculation of the wheel accelerating/decelerating speed and the calculation of the wheel slip rate are carried out, and the decompression threshold value at the start of decompression of the brake hydraulic pressure of a wheel cylinder is set at 85% (slip rate of 15%) of the pseudo car body speed. Further, the wheel speed selection value and the decompression threshold value are compared, and if the rear wheel speed selection value is smaller than the decompression threshold value, the brake hydraulic pressure decompression control is carried out. Further, when the rear wheel speed selection value is large, i.e., the wheel slip rate is small, if the wheel accelerating/decelerating speed is larger than a prescribed holding level, it is judged that the hydraulic pressure of the wheel cylinder is tacking, and the brake liquid boosting control is carried out.

Abstract: PURPOSE:To prevent the rapid improvement of picture quality at a certain value and to gradually improve the picture quality by continuously actuating a picture quality improving circuit part, which performs an emphasizing operation to a prescribed frequency of a regenerative FM luminance signal, corresponding to the level of the regenerative FM luminance signal. CONSTITUTION:This circuit is provided with a picture quality improving circuit part 10 for performing the emphasizing operation to a prescribed frequency of the regenerative FM luminance signal when the level of the regenerative FM luminance signal is turned to a prescribed level, and a variable impedance circuit for actuating the picture quality improving circuit part 10 corresponding to the level of the regenerative FM luminance signal with no step. When a diode D is conducted, an FM peaking circuit 8 for picture quality improvement is grounded in the manner of AC through the diode D and a capacitor C3 and this, the emphasizing operation of the regenerative signals is performed. On the other hand, the more the level of the regenerative signal is decreased, the more the degree of conduction of the diode D is increased corresponding to the decrease of the level. Therefore, when the degree of conduction of the diode D is increased, corresponding to the increase, the signal is continuously emphasized.

Filed: 1988-09-22
Abstract: PURPOSE:To constitute a printing device which can execute high speed recording at a low cost by providing a sub-scanning use coil on a film provided with a thin film type magnetic head. CONSTITUTION:In a magnetic head unit, a thin film type magnetic head 2 formed on a resin film 3 being movable in the axial direction of a magnetic drum 1 is placed and a sub-scanning coil 5 provided on a part of the film 3 is placed between magnets 4. When a pattern of the coil 5 is placed as shown by 405, and a current is allowed to flow with D as a magnet placing area, roughly constant force is received in the right direction during (x) extending from an initial position L1 to L2. This force does not become large force locally to the head, comparing with a method for receiving it mechanically from the outside, rigidity of the head becomes small and it can be made light in weight, and acceleration is in inverse proportion to weight of a movable part, therefore, the magnetic head unit can be driven at a high speed.

Title: Image forming device
Inventor: HIGETA AKIRA
IPC: G03G15/00
Filed: 1992-08-17
Abstract: PURPOSE:To prevent the generation of an electrifying noise by making an image carrier by the use of solid resin and providing a damper which absorbs the vibration of an electrifying means, and to prevent soiling of the electrifying means and the image carrier by separating them. CONSTITUTION:In order to prevent the generation of electrifying noises which result from the vibrations of the image carrier 2-1 and the electrification roller 2-50, the image carrier 2-1 is made of a solid material, so that the same effect as in the case where a vibration-proof material of the maximum width is attached to the inside of a hollow image carrier is obtained and the mass is also increased. A dynamic damper 2-52 is disposed on an electrification roller cover 2-51; thereby, when an image forming device is actuated, the damper receives the vibration of the electrification roller 2-50 via the electrification roller cover 2-51 and vibrates together. Since, in a system, the dynamic damper 2-52 is more vibratile than the electrification roller cover 2-51, the dynamic damper 2-52 vibrates and the electrification roller cover 2-51 doesn't. Therefore, the amplification of vibration resulting from transmission to other container, etc., can be prevented.

Title: Frequency distribution measuring circuit
Inventor: MIZUKAMI ICHIRO
IPC: G04F10/04
Filed: 1991-08-27
Abstract: PURPOSE:To remove an increase in the capacity of a memory by adding a counter for delaying packet start, a register for setting delay, a coincidence circuit for detecting delay, the frequency divider of a flip flop for storing a detection result, a counter and a memory for storing frequency. CONSTITUTION:A counter 2 has function for delaying measurement start time and this delay is determined on the basis of the clock frequency set by a register 3. A counter 10 takes the AND of the output of a flip-flop 7 and a clock to count a burst clock. The value obtained by counting a packet interval by the counter 10 is sent to a frequency memory 6 through a multiplexer 4 and the memory 6 stores the frequency of the count value but does not store a part showing no change. By this constitution, since counting is started from an arbitrary start point, a measured result of high resolving power is obtained even by a memory of definite capacity.
