Title: Adjustment method of corpuscle powder sample for scanning-type electronic microscope
Inventor: SAWAMURA SHINICHI
IPC: G01N1/28
Filed: 1978-07-20
Abstract: PURPOSE: To observe condensed corpuscle powder as primary particles by dispersing sample minute powder in a specific solvent under a primary particle state and dropping this solvent onto the adhesion face of an adhesive tape to evaporate the solvent and fixing this powder under a two-dimensional distribution state.  
     CONSTITUTION: Uranium oxide powder of primary particle diameter 0.2 to 0.5μm is added to low-level alcohol, for example, with a concentration of 0.5 to 1.5 weight %, and dispersion is promoted by an ultrasonic vibrator. Next, this dispersive liquid of approximately 0.1cc is dropped onto the residual adhesion face of a both-side adhesive tape of 8×8mm which has one face fixed to the metallic sample stand of a scanning-type electronic microscope. Then, the solvent is evaporated by vacuum drying, etc. After drying, a conductive thin film such as Au is formed into approximately 100Å thickness throughout the surface of the both-side adhesive tape by the vacuum evaporation method and the sputtering method. Then, a conductive paint such as an Ag paste is applied to four corners of the both-side adhesive tape to obtain conduction to the sample stand. As the result of observation with the fixed powder sample adjusted in this manner, a sufficient observation can be performed with a scale factor of approximately 30000.

Filed: 1981-06-08
Abstract: PURPOSE:To detect the incoming signal and the circuit current through an extremely simple constitution, by using a switch element to switch the load resistance of a photocoupler by the reception waiting mode and the incoming mode. CONSTITUTION:The incoming signal is supplied to the LED14 and 15 of a photocoupler 13 from a circuit via a call transformer 19. In the incoming waiting state, a switch 22 is turned off. A load resistance 20 having a large resistance value is connected to the collect of a phototransistor TR16. The envelope curve output of the incoming signal is supplied to an input terminal 17-2 of a control circuit 17. The switches 22 and 25 are turned on when the incoming signal is detected, and a message is recorded and reproduced by a recorder/reproducer 23. After the incoming, a resistance 21 having a sufficiently low level of resistance is connected in parallel to the collector of the TR16. Thus the load resistance is extremely reduced to allow the assured detection for the cutoff of the circuit current. Thus the detection is simplified for both the incoming signal and the circuit current.

Title: Rom device
Inventor: SATO AKIHIRO
IPC: G11C17/00
Filed: 1987-04-10
Abstract: PURPOSE:To reduce the electric current consumption of a ROM device, by setting the ROM device to its operating state only when address signals change and to a standby state when no change takes place in the address signals. CONSTITUTION:When delaying pulses 47 are added to a clock inputting terminal, an address holding circuit 1 fetches and holds address inputting signals 21 and uses the holding content as address signals 22. A discordance detecting circuit 2 compares the signals 22 with address inputting signals 31 and, when they coincide with each other, sets low-level signals to discordance signals 33. When they do not coincide with each other, the circuit 2 sets high-level signals to the discordance signals 33. A delaying pulse generating circuit 6 generates delaying pulses 44 of a 1st stage and delaying pulses 47 of a 2nd stage from change in the discordance signal. An output data holding circuit 7 holds the output data of a ROM 8 by using the pulses 44 as clock input and sets the holding content as output data 52. When the current address input signal 31 coincides with the last address signal 22 and when a standby requesting signal is inputted from the outside to an input terminal 4, the ROM 8 is set to a standby state by the output of a NAND gate 3.

Abstract: PURPOSE:To set data in a state that the data can not be read out to an external part after a program is written to an internal PROM by setting a flag for read program is written to an internal PROM by setting a flag for read prohibition when a counter counts the number of times for a general PROM writer to access all the addresses of the internal PROM. CONSTITUTION:A ternary counter 3 counts the number of times for all the addresses of a PROM 1 are accessed and when the counter 3 overflows, a flag set signal C1 for read prohibition is outputted. Then, a flag 2 is set. When the flag 2 is set, a gate 4 is closed by a read prohibiting signal C2 and it is made impossible to read out the data stored in the PROM 1 by write confirming operation. Thus, after the program is written into the built-in PROM by using the general PROM writer, the data stored in the PROM can be automatically set in the state that the data can not be read out. Then, the program can be easily protected.
