Patent JP-S61216424-A (JP)
Title: Conveyor for semiconductor substrate into heat treating furnace
Inventor: SHIMONISHI YASUYUKI
IPC: H01L21/22
Filed: 1985-03-22
Abstract: PURPOSE:To keep the speed of temperature rise and temperature drop of a semiconductor substrate constant by forming a feedback loop, which computes the speed of temperature rise and temperature drop of the semiconductor substrate and changes the speed of a motor through a speed control means. CONSTITUTION:Voltage detected by a thermocouple 21 is amplified through an amplifier 22, transmitted over an A/D converter 23 and changed into a digital signal, and transmitted over a micro-computer 24. The speed of temperature rise or temperature drop is computed at that time, and a signal maintaining a present state is emitted when the speed is kept within a proper range and a signal changing the speed when the speed is not kept within the range. The signal is D/A converted, transmitted over a servo controller 26, and current- amplified and a motor is driven at constant speed. Semiconductor substrates 34 are set onto a boat 36, and pushed into a heat treating pipe 33 by a quartz bar 35. A thermocouple 37 is set to the boat 36, and a substrate charge 38 drives the quartz bar 35 and the thermocouple 37. Signals from the thermocouple 37 at one position or more are transmitted over the motor through a loop. Accordingly, the deterioration of yield due to blooming can be inhibited.
Patent JP-H05256881-A (JP)
Title: Asynchronous calibration circuit and frequency detection circuit
IPC: G01R35/00
Filed: 1992-03-16
Abstract: PURPOSE:To highly accurately detect a frequency at a high speed by selecting a plurality of frequencies after setting a frequency sampling section and finding voltage levels at every frequency of a plurality of sampling frequencies, and then, narrowing a measuring section by omitting sampling points where the degree of proximity is small. CONSTITUTION:The measuring point of a sampling measuring section S1 is set at three points of an upper limited frequency f1, lower limited frequency f3, and intermediate frequency f2 so that an initial measuring section S1 can be divided into two parts. By performing FFT(fast Fourier transformation) on sampled values at the frequencies f1, f2, and f3, voltage levels V1, V2, and V3 are found and the magnitudes of the levels are discriminated. When a relation V1<V2<V3, can be established among the voltage levels, the section between the frequencies f2 and f3 corresponding the levels V2 and V3 is set to a new measuring section S2. Then voltage levels at three points of frequencies f2, f3, and f4 are found and the magnitudes of the voltage levels are discriminated. Thereafter, the measurement is repeated until desired resolution is obtained so that a sampling point having a high voltage level can be left by repeating the same steps. Finally, the corresponding frequency f0 and the real frequency F0 of AC signals can be recognized.

Title: Electrical alarming device and its production
IPC: G10K9/13
Filed: 1992-03-16
Abstract: PURPOSE:To provide the electrical alarming device which has an exact resonance frequency and is simple in construction and adjustment and the process for production of this device. CONSTITUTION:The peripheral edge 10 of a diaphragm 1 is fixed to the peripheral edge 20 of a housing 2 and the housing 2 oscillatably holds the diaphragm 1. An electromagnet (excitation coil) 6 to be fed with intermittent currents vibrates the diaphragm 1 by magnetic force. The two peripheral edges 10, 20 have an overlap part extending in the vibration direction of the diaphragm 1 and these overlap parts are relatively movable in a vibration direction before fixing. The diaphragm 1 and the housing 2 can, therefore, be moved relatively in the vibration direction while the overlap part of both is held in an occasionally fixable state. As a result, both can be adjusted and held in the positions where the relative distance between both attains a prescribed reference distance and can thereafter be fixed.

Title: Semiconductor memory
Inventor: SUZUKI SEIGO
IPC: G11C7/12
Filed: 1982-04-09
Abstract: PURPOSE:To enable quick readout of data by changing a resistance value of a load element connected to a column line according to charge and discharge. CONSTITUTION:A signal A that controls charge and discharge of a column line 30 generates at a switching point of address signal AD1. When the signal A is at a high level a transistor Tr 12 is made on state and charge to the column line 30 is effected. At this time, as a load element 11 is also in a state of conduction, precharge to the column line is made through Tr 11, 12 and resistance at the  time of charging becomes small. Consequently, time required for precharge of the column line is shortened remarkably. When the signal A is at low level, Tr  12 is in off state. Therefore, resistance at this time is the same only that of Tr  11. As Tr 11 is used to maintain 1 level of the column line 3, large resistance  value is preferable. Accordingly, discharge of the column line by the memory  cell is effected quickly and power consumption at this time becomes very small.
