Patent JP-H01150247-A (JP)
Title: Optical disk substrate
Inventor: MANABE DAISUKE
IPC: G11B7/2405
Filed: 1987-12-07
Abstract: PURPOSE:To prevent the decrease of signals from address bits and to narrow a track pitch by interrupting the grooves for tracking in the part adjacent to the respective address bits in an address bit part. CONSTITUTION:The grooves 1 for tracking are not formed in the part adjacent to the address bits 2 in the address bit part and are interrupted by as much as the length of the bits 2 in the part of the bits 2 to form a grooveless section 3. The exposing of the grooves for tracking is thereby prevented at the time of exposing the address bits and, therefore, the fogging by the overlap of the two laser beams for exposing is prevented and the decrease of the signals from the address bits is prevented even if the track are formed to the smaller pitch. Since the section 3 is short in length, the tracking is not hindered. The formation of the tracks to the smaller pitch is, therefore, possible.

Title: Image data processing method and device therefor
Inventor: KUBOTA KATSUYASU
IPC: H04N19/00
Filed: 1993-11-16
Abstract: PURPOSE:To compress the image data with no deterioration of the picture quality perceived for the reproduced images, at the compression rate increased as much as possible and with high efficiency. CONSTITUTION:A plane image is divided into plural image component elements and the density data on each component element is defined as a function of the variable set on the two-dimensional coordinates. This function is converted into a function of the variable set on the frequency coordinates and each frequency function is quantized. The frequency to be quantized is previously changed, and an image formed based on the unchanged frequency function is compared with an image formed based on the changed frequency function. Based on this difference between both images, the limit value is calculated for the changed variable of the frequency function that is unperceivable to the human eyes. Thus the frequency functions are quantized so that the difference between the unquantized frequency function and the frequency function that is inversely quantized after quantization is increased as much as possible within its limit value.

Abstract: PURPOSE:To make it possible to perform balancing operation quickly by observing the data of S/V curves, giving the instructions for two kinds of numbers of rotations, and automatically inputting the data of the specified numbers of rotations into a balance arithmetic circuit. CONSTITUTION:Time-axis signals detected with oscillation detectors 1A and 1B undergo A/D conversion in an A/D converter 3. The degrees of the signals are analyzed in a FET processor 4. Then, in an S/V circuit 5, only a first-order component is extracted out of the spectrum whose degree is analyzed in the processor 4. The data of the amplitude and the phase are stored, and S/V curves are plotted. The pulse signal from a rotary pulse detector 6 is detected with a balance operating circuit 8, and the start of the sampling in the circuit 3 is instructed. The degree of the sampled data is analyzed in the processor 4. Only the first-order component among the data is inputted into the circuit 5. When the fact that the data are stored in the S/V curves is instructed to the circuit 8 from the circuit 5, the circuit 8 detects the next circuit pulse and gives the instruction for the next sampling to the circuit 3. This operation is automatically performed from the number of rotation at the start of the measurement to the number of rotation at the end of the measurement.

Title: Steam iron
Inventor: KATAOKA YOSHINORI
IPC: D06F75/20
Filed: 1988-12-09
Abstract: PURPOSE:To prevent the jet-out of steam having a high temperature when an iron falls down in nonuse state by allowing a state detecting means to detect the nonuse state of the iron and releasing the setting of water supply of a water supply control means. CONSTITUTION:A water supply control means 19 confirms the state of an iron by always confirming the output of a state detecting means 21, and if the iron maintains a horizontal state, it is judged that the iron is in use, and a motor- driven pump 16 is operated to perform water supply control. When an operator sets the iron in the erection state in order to correct the state of a clothes under the iron operation, the state detecting means 21 outputs the erection state into the water supply control means 19. A water supply control means 20 releases the setting of water supply according to the output. Even if the iron falls down from the erection state and is set into the horizontal state, the water supply control means 19 keeps the motor-driven pump 16 in nonoperation state, and the jet-out of steam is prevented.

Abstract: PURPOSE:To realize low electricity consumption characteristics, by causing a transistor to be operated by using a barrier corresponding to about one-half of bound energy of impurities which is produced between a degenerate semiconductor and a semiconductor where charge carriers are frozen. CONSTITUTION:This transistor is composed of single crystal germanium layers 11, 12, and 13 where an N-type semiconductor highly concentrated by arsenic impurity is degenerate on a P-type single crystal substrate 10 of germanium and the single crystal germanium layers 14 and 15 where, being sandwiched by the layers 11, 12, and 13, they have electrons which are N-type change carriers low concentrated by arsenic impurity and are frozen. Most of the electrons which come out by passing from the layer 13 to the layer 15 travel in a state that they are not scattered at all and, even when they reach the layer 14, their energy has the height of barrier ED/2 or more and their occupied positions can be found in their conduction bands of the layer 14. As soon as the electrons come in the layer 14, they are accelerated by electric fields produced by a voltage VBC between base and collector electrodes and travel the layer 14 to reach the collector electrode 16. As a result, the current of the collector flows and its flow of electricity allows the transistor to perform its switching motions.
