Title: Logical circuit
Inventor: NAKAMURA HIDEO
IPC: G11C17/12
Filed: 1985-04-05
Abstract: PURPOSE:To reduce electric power consumption and occupying area of a ROM circuit by supplying the decoder output from a NAND circuit via an inverter to the gates of the ROM cells of a NOR circuit so that the flow of through-current to the ROM cells is prevented. CONSTITUTION:The output from a decoder part 20 of the NAND circuit provided with N type FET01-0i for logical gates between P, N type FETs 21 and 22 for precharging and switching is supplied via the inverter 31 to the gates of the ROM cells of the N type FETs 311-3MN of the NOR circuit. The floating capacity between the FETs 21 and 01 of the output line of such decoder 20 is slight as compared with the floating capacity of the output lines 410-4N0 of the ROM. The FETs 311-3MN are turned off even if the FETs 21, 41-4N are simultaneously turned on and the flow of the through-current is thus prevented. As a result, the need for providing a transfer gate between the ROM cells and the ground is eliminated and the electric power consumption and occupying area of the ROM circuit are reduced.

Abstract: PURPOSE: To obtain a Schottky diode containing the guard ring of a small junction capacity by extending and inserting part of the P-type guard ring layer between the electrode and the insulator film of the N-type Si substrate.  
     CONSTITUTION: SiO 2 7 and P-type poly Si34 are laminated on N-type Si substrate; the eave part is formed to layer 34 by the selective etching; and the substrate is covered again with P-type poly Si51. Then the ion etching is applied to leave layer 34 and layer 37 under the eave part in order to form layer 38. The heat treatment is carried out to form P-diffusion layer 4 from layer 38, and then guard ring 5 and pn junction 3 are formed respectively. After this, metal layer 18 is laminated to obtain Schottky junction 9 and then to form the ohmic junction between junction 9 and P-layer 4. Electrode 8 is formed and layer 38 is etched to form layer 10 with electrode 11 attached to the rear surface of the substrate. In this case, layer 7 is distant away from the electrode by the amount of the thickness of layer 10, and thus no alloy is produced with the substrate. As a result, layer 4 can be made shallow with reduced capacity of junction 3, accordingly facilitating the manufacture and increasing the yield.

Title: Sample evaporator
Inventor: SENOO KAZUHIRO
IPC: H05H1/24
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain rapidly a stable amount of beam by rapidly and positively heating sample without changing PID(proportional, integral, differential) control during course. SOLUTION: A spacer 9 is provided between an oven 3 and a thermo-couple 8 for temporally delaying the heat conduction from the oven 3. When measuring the temperature of the oven 3 through the spacer 9, the heat of the oven 3 is not instantly transferred to the thermo-couple 8 so that the response of the thermo-couple 8 will be slow. Thus when heating the oven 3, the actual oven temperature may be higher than the measured temperature of the thermo-couple 8. Since the oven temperature is controlled according to the measured temperature of the thermo-couple 8, if the heating of oven 3 is suppressed based on the measured temperature, the oven 3 itself will be sufficiently heated at that time so that the sample 5 in the oven 3 also will be sufficiently heated.
