Title: Speed modulation transistor
Inventor: KUROBE ATSUSHI
IPC: H01L29/80
Filed: 1992-12-14
Abstract: PURPOSE:To heighten the amount of variation of a conductivity by a method wherein an active layer is formed so that conductive band energy in a part between first and second hetero interfaces may differ from the conductive band energy in a part in the vicinity of the first and second hetero interfaces. CONSTITUTION:For instance, an active layer 4 can be formed so that conductive band energy in a part between a first hetero interface A (front barrier layer 5) and a second hetero interface B (back barrier layer 3) may sufficiently make greater than the conductive band energy in a part in the vicinity of a first hetero interface A and the conductive band energy in a part in the vicinity of a second hetero interface B. If so, when carriers localize within a front conductive channel or a back conductive channel, dispersion of localized channels in short a flow of the carriers into the channel on the opposed side to the localized channel can be prevented. Thus, the amount of variation of a conductivity can be heightened without causing a deterioration of an element characteristic.

SOLUTION: When there is a connection request from a slave station input/ output device 3#n during data collection while connecting a slave station input/ output device 3#1, a master station processor 4 operates a telephone call catch processor 5 and a telephone call holder 6. Due to this operation, data collection under connection is held, the slave station input/output device 3#n is connected by using the telephone call catch function, and a priority comparator 7 investigates the presence/absence and content of priority bit in the transmission data. Based on this result, the master station processor 4 first collects the data from the slave station input/output device 3#1 or 3#n having higher priority and collects the next data after the end of this collection. Thus, data can be collected in the order beginning with the highest priority.

Abstract: PURPOSE:To cut off noise components and to improve SN ratio by generating a filter output while selecting a longitudinal edge which has a high horizontal frequency and a low vertical frequency and a lateral edge which has a low horizontal frequency and a high vertical frequency. CONSTITUTION:A signal inputted to an input terminal 11 is inputted to a 1st signal processing circuit 30 and a 2nd signal processing circuit 40.

When the longitudinal edge shown in a figure 26 is inputted, the output level of the 1st comb filter 50 drops and the output betaof a low-pass filter 15 further decreases. At the time, the output level of the 2nd comb filter 60 rises and the output alpha of a high-pass filter 16 increases. When the signal shown in a figure 24 is inputted, on the other hand, the output betaof the low-pass filter 15 increases. The two-dimensional frequency component of the input signal can be determined by comparing the levels of the signals alphaand beta with each other.

Filed: 1987-12-29
Abstract: PURPOSE:To stabilize tracking even in case of wrong linearity by selecting and tracking only one part out of tracking signals when discrepancy is detected between a track and traces of a head. CONSTITUTION:The regenerating signals of heads 2a and 2b are amplified by a head amplifier 13, and its output is inputted to a signal processing circuit 15 where data including error detecting codes recorded divisionally in the first half and latter half of a track are processed.

IPC: H01M10/0566
Filed: 1990-11-29
Abstract: PURPOSE:To improve the utilization factor of positive electrode and negative electrode active material by adding material as subactive material possible to be discharged from the start to a positive electrode with LiC0O2 as main active material. CONSTITUTION:A bit of positive electrode subactive material such as manganese dioxide possible to be discharged from the start of assembling is added to a positive electrode 1 with LiC0O2 as positive electrode main active material. As a result, initial discharge is allowed and in the initial discharge an inactive coating is removed from the surface of a negative electrode 4. It is thus possible to effectively use positive electrode 1 and negative electrode 4 active material because charge reaction proceeds on the whole surface of the negative electrode 4 in an uniform and good condition during charge after previous discharge and restrain electrodeposited lithium from growing in a dendrite form.

Filed: 1990-11-29
Abstract: PURPOSE:To prevent an unqualified person from using illicitly an information processor while a qualified operator is absent by carrying out again an illicit use inhibiting means after detection of the presence or absence of the operator in his/her seat and with input of a detection signal showing the presence of the operator after an absence state. CONSTITUTION:A light emitting element 6 is provided at the front of a terminal and emits the infrared rays, and a light receiving element 7 detects the light emitted from the element 6 and reflected by an operator. Then an operator presence detection circuit 8 containing both elements 6 and 7 sends an interruption signal to a processor 1 when a detection signal showing the absence of the operator is received from the element 7 in an active state of an information processor. Then the illicit use of the information processor is inhibited when the signal showing the presence of the operator is inputted after the input of the interruption signal. Thus it is possible to reconfirm an identification number when the operator is present again in his/her seat and to prevent such an inconvenient case where an unqualified person operates the processor while the qualifies operator is temporarily absent.

When the present position attains the value PA, it is decided at a step 106 whether a difference between a present position and an objective position is within a given value. When the difference outside the given value, at a step 105, a spring constant in a target position is hardened and the decision value PA is computed. At a step 108, it is decided whether a grinding remaining amount all in route positions is a given amount.  When it is a given value, grinding is completed and when a remaining amount is outside a given value, it is decided at a step 109 whether the present position is a terminal. When it is a terminal, the objective position is reset to a starting end, and a return to a step 101 is effected. When the present position is not a terminal, at a step 110, the present position is updated to the objective position, where grinding remains, and a return to a step 101 is effected.
