Title: Drive control method for cart
Inventor: WAKAUMI HIROO
IPC: G05D1/02
Filed: 1988-01-29
Abstract: PURPOSE:To realize the non-stop drive of a cart in the shortest course with avoidance of obstacles by adding the sensors to the cart to detect the obstacles existing in the front and at the right and the left and securing the fixed distances between the cart and the obstacles. CONSTITUTION:In case a front sensor detects an obstacle P1 while a cart 10 is passing through a point S together with detection of a magnetic marker Y1, the cart 10 has the autonomous drive between the points A and C along a curved path 11. The bias angle of a driving/steering wheel is set back at zero at the time point (point C) when the distance traveled reaches a prescribed level. If a left sensor detects the obstacle P1 under such conditions, the cart 10 undergoes the guided straight drive for the time being. Then the cart 10 has the curved autonomous drive to the left at the time point (point D) when the obstacle P1 is not detected at the front left. Thus the cart 10 travels up to a point J through a point G and returns to the original guide line Y1. For this purpose, the guided straight drive is given to the cart 10 up to a point K and the cart 10 has the autonomous curved drive after the point K and up to a point M set on the line Y1.

Title: Digital modulation method
Inventor: SHINPO MASATOSHI
IPC: H03M7/14
Filed: 1983-02-10
Abstract: PURPOSE:To attain the high density of magnetic recording by realizing self- clocking and at the same time reducing greatly the maximum magnetization inverting interval while maintaining the performance of 3PM. CONSTITUTION:An FEM-4 converts the data of 4 bits into a code word of 8 bits and then modulates the series of the code word by an NRZI. For the 1st rule of modulation of the FEM-4, the 8th bit P8 of a code word which is old in terms of time series is inverted to bit ''1'' in case the next two continuous binary data of 4 bits are combined. Then the 3rd bit P3 of the following code word is inverted to bit ''1''. For the 3rd rule of modultion of the FEM-4, the 2nd code word P1P2P3P4P5P6P7P8 and 00001000 are allowed to correspond to the 2nd data ''O'' which is set at the center in terms of time series in the case a combination of the next three continuous binary data. Here a conversion table of modulation method (FEM-5) is shown for this invention. The 1st rule of modulation of the FEM-5 is equal to the 1st rule of modulation of the FEM-4, and the 2nd rule of modulation of the FEM-5 is equal to the FEM-4. Then the 3rd rule of modulation of the FEM-5 corresponds to the 3rd modulation rule of the FEM-4.

Abstract: PURPOSE:To realize dielectric breakdown instantly and certainly by furnishing a self-exciting oscillator circuit which uses a serial resonator circuit as a constituent member and impresses the output oscillated with the resonance frequency of the resonator circuit on an inverter circuit. CONSTITUTION:When a switch is put on, a self-exciting oscillator circuit 6 starts operating to give a signal with a frequency fm to a drive part 3. The drive part 3 gives an input signal with frequency fm to an inverter circuit 2, and the output therefrom which is an AC voltage with frequency fm is boosted by a booster transformer 2c into a specified voltage, which is fed to an LC serial resonator circuit 4. Voltage drop generated in a resistance 4d at this time is fed back to the oscillator circuit 6 via a TTL level converter circuit 7. Thereby a new self-exciting oscillator circuitry is formed, and the frequency fm shifts to the resonance frequency fo of the LC serial resonator circuit 4 which has higher Q. The time in which the frequency fm shifts to fo is an order of magnitude of several mus, and the high voltage grown by resonance is impressed on a discharge lamp 5 to cause a dielectric breakdown in a period of time approx. 220mus.

IPC: H01L21/027
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a method of forming a resist pattern which prevents the developed resist position from becoming T-shaped, improves various characteristics and realizes a highly integrated device pattern. SOLUTION: This forming method comprises the steps of adjusting a pre- baking temp. and time according to the b.p. of a resist solvent to control the diffusion length of an acid in the resist film, the acid being produced from an optical acid producing agent, thereby optimizing the acid diffusion length, while keeping the dissolution contrast optimum. This increases the gradient of the dissolution characteristic having the highest influence on the resist performance, thereby ensuring high resolution and making good acid diffusion length. Hence, after developing, this prevents a resist pattern 302 on a wafer 301 from becoming T-shaped, improves the resolution, focusing depth, dimensional accuracy, etc., and enables the formation of a rectangular resist pattern.

Furthermore, an object frequency FH'' at the adjustment of the trimmer 4 is obtained according to the theoretical formula by using the values FL' and FH' and standard values FL and FH. Then the coil 1 is set to the Lmin and the coil is set to the initial state and the trimmer 4 is adjusted until the oscillating frequency becomes the FH''. Then the coil 3 is adjusted until the frequency reaches the FH while the coil 1 is kept to the Lmin. As the result above, the oscillating frequency at the Lmax is the FL. Then in measuring the frequencies FL' and FH', the trimmer 4 and the coil 3 have only to be adjusted only once each in a high frequency.

Abstract: PURPOSE:To enable the reduction of a base electrode wiring resistance by using a silicon nitride film on a first polysilicon film as a mask for converting the bottom and side planes of an opening for forming an emitter into a silicon oxide film. CONSTITUTION:After forming an opening 23 for forming an emitter on a base region 22, thermal oxidation is performed by using a silicon nitride film 19 as a mask, thereby forming a thermal oxidation silicon film 24 on the bottom and side planes of the opening 23 and a collector contact forming region. Furthermore, a silicon oxide film 25 is formed over the whole surface. Next, the silicon oxide films 24 and 25 covering the bottom plane of the opening 23 and the collector contact forming region are removed to leave the silicon oxide film only on the side planes of the opening 23. By this treatment, the thickness of the silicon oxide film left on the side planes of the opening 23 is controlled. Accordingly, the distance between emitter and base electrodes can be controlled and a base resistance can be lowered by shortening said distance.
