Inventor: KIN MEIJUN
IPC: G06T9/00
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To improve recording density on a digital recording medium by inputting data in another specific data unit and encoding the inputted data when the number of continuous specific bits is smaller than a prescribed value at the time of encoding inputted data in each specific data unit and connecting plural encoded code words. SOLUTION: When the number of continuous '0's is smaller than (d) at the time of executing the RLL encoding of data inputted in each data unit having lst bit length by (d, k) code words (step 110) and connecting two code words, the data are inputted in each data unit having 2nd bit length and the RLL encoding of the inputted data is executed (stetps 120 to 140). For instanace, RLL (3, 15) encoding for restricting the number of continuous '0's to three to fifteen '0's is adopted. The signal moclulation method includes main conversion encoding and sub-conversion encoding and the main conversion encoding receives input data in each 3-bit unit and generates 7-bit encoded bit data. On the other hand, the sub-conversion encoding receives the input data in each 6-bit unit and generates 14-bit encoded bit data.

Title: System and method for detecting fault of network
Inventor: CHIYAARUSU EICHI HOWAITOSAIDO
IPC: H04L12/40
Filed: 1992-06-26
Abstract: PURPOSE: To non-interferentially detect the fault of a network by counting the number of transmitted information packets, the number of damaged information packets, or the number of prescribed level information packets. CONSTITUTION: A medium access MAU 302 receives a signal from a network bus 300, detects the appearance of an information packet on the bus 300, discriminates the occurrence of collision between information packets on the bus 300, and transmits data to the bus 300. The MAU 302 also generates and receives signals. A network interface device 308 translates the signals from the MAU 302 through a data line 306 so that other elements can utilize the signals. When the interface device 308 receives a signal indicating the appearance of the information packet on the bus 300 from the MAU 302, a signal indicating that a counter 312 must be increased by '1' is sent to the counter 312 through a data line 310 and, when the MAU 302 detects a collision, another network interface device 314 sends a signal indicating that a counter 316 must be increased by '1' to the counter 316.  Therefore, the fault of a network can be detected non-interferentially, because the interface device 308 fulfills a counter increasing function in such a way.

IPC: H01L21/302
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To reduce the capacitance between a gate and a source and improve switching characteristics by decreasing an angle formed by a tangential line of the inclination of a trench inner surface and a semiconductor layer surface toward the semiconductor layer surface from the lower end of a channel region. SOLUTION: An N-type epitaxial layer 21 is formed on an N-type semiconductor layer 20, and a P<+> -type diffused layer 22 is formed on the surface. On the entire surface, an NSG film 51 is formed through LPCVD. An oxide film 50 and the NSG film 51 are etched so as to expose the parts corresponding to trenches 23 to be formed, and a silicon substrate is subjected to dry-etching. By anisotropic etching using HBr as the main gas, V-shaped trenches whose sections protrude toward the trench inside are formed. Since the V-shaped trenches are used, capacitance formed between polysilicon embedded in the trenches, a gate oxide film formed on the trench surface and the semiconductor substrate can be reduced, and the values of Cgs and Cgd can be made small. Thereby the switching speed can be improved.

Title: Cylinder shaped liquid sealing rubber vibration isolator
Inventor: OKAMOTO SHUICHI
IPC: F16F1/38
Filed: 1988-08-03
Abstract: PURPOSE:To aim at stillness in a compartment by low vibration by providing a first and a second liquid chambers between an inner and an outer cylinders disposing the first liquid chamber at the most susceptible part to displacement by vibration and the second liquid chamber around the first liquid chamber and having both liquid chambers communicated by means of an orifice. CONSTITUTION:When the dead load acts on a rubber vibration isolator in the state of supporting an engine, if an outer cylinder 1 is lowered on the basis of an inner cylinder 2 due to being subjected to vibration, a first liquid chamber 4 is influenced by the displacement of the outer cylinder 1 more than a second liquid chamber so as to increase its volume variation and be fluctuated to the decrease side. As a result, liquid 17 flows from the first liquid chamber 4 toward the second liquid chamber 5 through an orifice 8. When the outer cylinder 1 rises on the contrary, the liquid 17 flows in the opposite direction. The vibrational energy is thus damped by the liquid 17 that flows through the orifice 8 in addition to the damping action of a vibration proofing substrate 3. Accordingly, the large damping force can be obtained so as to prevent transmitting the vibration to the inner cylinder 2.

Title: Digital data processing circuit and digital data processing method
Inventor: YAMAZAKI MOTOHIRO
IPC: H03H17/02
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To suppress sound quality deterioration caused by truncation noise due to a filter operation at the time of encoding and decoding and also to prevent a circuit scale from being increased. SOLUTION: Positive and negative signs are inverted by multiplying output data of an encoding circuit 1 by -1 by a multiplier S1, and the data whose signs are inverted by the inversion processing are returned to the original signs by multiplying output data of a decoding circuit 2 by -1 by a multiplier S2. Thereby, truncation noise which occurs in each of the circuits 1 and 2 at the time of a filter operation is canceled. This suppresses the sound quality deterioration due to truncation noise and also prevents a circuit scale from being increased.

Abstract: PURPOSE:To make it possible to detect the horizontally with high accuracy, by employing a box which has an upper surface thereof made of a transparent plate, and side and a bottom surfaces thereof made of super-conductive material, and a magnet which floats in the box by the Meissner effect, for simplification in usage. CONSTITUTION:A magnet 9 is accommodated within a box which has its upper surface made of a transparent plate 3, and its side and bottom surfaces made of a super- conductive material. The box is curved downwards at the upper and bottom surfaces thereof. The box is accommodated in a casing 1. When the casing 1 is put on a surface to be measured, since the magnet 9 is floating because of the Meissner effect of the super-conductive material 8, the magnet 9 is hardly affected by the friction force and moves in a guide section 8', and finally stops correctly at the lowest part of the curved surfaces of the super-conductive material 8 by gravity. Therefore, if the surface to be measured is a horizontal surface, a mark 9' indicated on the magnet 9 perfectly coincides with the center line of a scale 3' of the transparent plate 3. On the other hand, if the scale 3' is set in advance so as to correspond to inclination angles of the surface to be measured, the inclination angles of the surface when it is inclined can be correctly detected.
