Inventor: SATO KOICHI
IPC: H01L21/82
Filed: 1989-09-13
Abstract: PURPOSE:To shorten the operation time to form a coordinate grid according to an object to be analyzed by a method wherein, instead of the potential distribution of a numerical simulation, a concentration distribution of impurities in an input data is utilized as a physical quantity controlling the concentration of the coordinate grid. CONSTITUTION:A structure of a semiconductor as an object is formed at a geometric- shape data formation part 41 while a numerical value of coordinates of its vertes is input via a pick or an operation panel 6 by using a light pen or the like. An impurity distribution function is selected from predetermined patterns; its parameter is designated; also an impurity distribution in a corresponding substance region over the whole region is formed. Then, a parameter controlling the interval between grid lines on the basis of a previous geometric-shape data is input at a coordinate-grid formation part 42. At a coordinate-grid correction part 43, a coordinate grid formed in a pretreatment is displayed on a display device 2 together with the concentration distribution of impurities; the coordinate grid is added, deleted or the like via the pick by using the light pen or the like.

Title: Temperature controller for electrical heating apparatus
Inventor: KURIHARA ISAO
IPC: G05D23/24
Filed: 1987-09-18
Abstract: PURPOSE:To quickly increase the surface temperature of an electrical heating apparatus up to a level near the set temperature by performing the fixed temperature control for a prescribed period of time based on a fixed level higher than the set temperature in case the temperature rises up with a fixed width within a reference time. CONSTITUTION:A 2nd constant temperature control means 5 selects a voltage level equivalent to the set temperature of a variable resistor 3 or a register 10 and supplies this voltage to a comparator 11 as a reference voltage level. The comparator 11 compares this reference level with the output voltage level of a temperature detecting circuit 2. If the level of the circuit 2 is lower than the reference level, a turn-on signal is produced for supply an AC power supply V which heats up a heater H. While a turn-off signal is delivered for cut-off of the power supply V in case the voltage level is higher than the reference level. Thus it is possible to quickly rise the room temperature up to a level near a set temperature in a quick heating mode where the room temperature is comparatively high.

Title: Circuit and method for processing variable length bit data
Inventor: TAKAHASHI TOYOFUMI
IPC: H04N19/42
Filed: 1994-09-30
Abstract: PURPOSE: To shorten the processing time and to increase the data processing speed by providing a latch of 3 words in total and plural selectors and a subtractor constituting a barrel shift means. CONSTITUTION: When barrel shift is used, data is right or left shifted by plural bits at a time in response to one clock. The number of bits by which data is shifted in response to one clock is determined by the extent of shift given from a subtractor 30. Consequently, a barrel shifter 16 selects 32 bits b0 to b31 given from second and third registers 20 and 22 or '0' in accordance with the extent of shift indicated by the subtractor 30. Data is barrel-shifted by a required number of bits as the result, and shifted-out bits are lost by barrel shift, and '0' is written in these bits. Thus, variable length bit data is taken out at a higher speed with the simple circuit.

A detecting circuit 13 decides that the drift exists when the counted value shown by the counter 12 is smaller than the prescribed value C1 or larger than the prescribed value C2, and decides that the drift will not exist when the value is larger than the prescribed value C1 and smaller than the prescribed value C2. Thus, the drift detecting circuit, which can be used without adjustment, can be realized.
