Title: Measuring device for transistor power gain characteristic
Inventor: ASHIZAWA UNJI
IPC: G01R31/26
Filed: 1978-10-12
Abstract: PURPOSE: To secure a quick and accurate measurement for the power gain characteristics by giving the preheating via the bias current before measurement.  
     CONSTITUTION: The measurement is carried out in the order of intial value PG 1 , the preheating conduction and IAGC. First, the start signal switches change-over switch K 2 11 to (a), and output variable power source 6 gives the initial bias current to DUT 5 . At that instant, output voltage V oa  is referred to as PG 1  to be held at sample holding circuit 12. Then switch K 2 11 is opened, and the prescribed preheating current flows to DUT 5  from power source 6. After this, source 6 generates the saw-tooth type voltage, and the gain of DUT 5  and also output VOC are decreased according to increment of the bias current. Output VOC is then compared with V oa  obtained previously through comparator 13. And when the coincidence is obtained through the comparison, output pulse SRB is generated. A comparison is given to the limit value to know in what range the bias current of that time exists. With such preheating, an accurate measurement is possible in a short time.

Title: Semiconductor memory device and manufacture thereof
Inventor: AKIYAMA YUKIHARU
IPC: H01L27/115
Filed: 1993-05-27
Abstract: PURPOSE:To realize reduction of a chip area of an electrically writable/erasable semiconductor nonvolatile memory (E<2>PROM) and also provide a simplified method of manufacturing the same. CONSTITUTION:A bias of a source region 13 of memory transistor can be lowered by applying a negative bias erasing method to E<2>PROM. Therefore, it is no longer necessary to form this region as a double diffused region. Moreover, since a transistor at a part of the peripheral circuit is formed as FET on a field oxide film 2, it is unnecessary to provide a diffused layer within the substrate 1 and moreover a chip area can be reduced. In the case where the TFT on the field oxide film 2 of E<2>PROM is formed, for examaple, in the stagger structure, a source 3, a drain 4, a channel 5 and a floating gate 10 of memory of this TFT are formed using a first polysilicon layer laminated simultaneously, and a gate 6 of this TFT, a control gate 8 of a transistor on the substrate 1 and a control gate 8' of the memory are formed using the second polysilicon layer laminated simultaneously. Therefore such semiconductor memory device can be formed very easily.

Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To suppress power consumption of the facsimile equipment by repeating the usual standby mode and the low power consumption standby mode periodically in the case that a reserved operation is set and continuing the low power consumption standby mode till a restoration cause is generated from the low power consumption standby mode when no reserved operation is set. SOLUTION: When a reserved operation is executed at a designated time, power of a printer 10 is interrupted to goes off all or some LEDs being components of a display section of an operating panel 4. Then a mask with respect to a cause to be restored from the low power consumption standby mode is released. Then a start signal control circuit 2 receives signals from surroundings on the occurrence of a restoration cause and issues a start signal to a CPU 1. Then the CPU 1 reads a program of a ROM 8, in which the usual standby mode and the low power consumption standby mode are periodically repeated. On the other hand, when no reserved operation is made, a facsimile equipment F transited to the low power consumption standby mode continues the low power consumption standby mode till a start cause other than a clock circuit 5 is produced.

Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To prevent plastic deformation and failure caused when external force is applied and, thereby, to enhance the reliability by disposing a stopper which regulates the displacement at a head of a teeth part. SOLUTION: The teeth part 3 is formed on a lead teeth 2 attached to an optical head 1 via a hinge part 6. The teeth part 3 is urged by a spring 8 so as to be always engaged with a lead screw 7 under proper pressure.

Filed: 1993-05-28
Abstract: PURPOSE:To allow the simultaneous measurement of the velocity and direction of a two-dimensional flow at an arbitrary position by projecting two laser beams while crossing in the fluid so that the plane defined by the beams intersects the photographing direction of a camera and then measuring the velocity of fluid based on the distribution of fluorescent intensity at a fluorescent part.

A YAG laser 1, a dye laser 2, and a wavelength converter 3 are operated to generate a laser beam 5 having a predetermined wavelength which is led into the probe 12 and projected into a gas flow 8 through a rotary reflector 15 thus setting a measuring position arbitrarily. In the measurement of velocity of a two-dimensional flow, the temporal moving distance at the intersection of two beams 5 can be obtained, i.e., the velocity and direction of flow can be determined simultaneously, from two photographs of fluorescent intensity distribution induced by two beams 5. This constitution allows instantaneous accurate measurement of the velocity and direction of two-dimensional flow at an arbitrary measuring position.
