IPC: G01B7/34
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a fixation method in which the probe of a scanning probe microscope can be fixed to an arbitrary position in a sample only at an arbitrary time interval, by a method wherein a change in terms of time of a microscope image due to the drift of the probe is tracked by overlapping the microscope image, and the amount of the drift generated at a time interval is computed so as to be compensated. SOLUTION: A reference microscope image in the arbitrary region of a sample is obtained. A driving signal which is given to the fine movement mechanism of a probe 12 is controlled. The probe 12 is moved to a desired position contained in the reference microscope image. A subreference microscope which contains the position is obtained. Then, the position of the subreference microscope image is computed, the probe 12 is moved to the previous position again, the driving signal is held only at a prescribed time interval, and an other microscope image is obtained after the time interval elapses.  Then, the position of the other microscope image in the reference microscope image is computed, and the amount of a drift generated during the time interval is computed on the basis of the comparison of the position of the computed subreference microscope image with that of the other microscope image. Then, the driving signal is controlled so as to compensate the amount of the drift, and the probe 12 is moved to the previous position. A step after the computation of the position of the subreference microscope image is repeated.

Title: Method and apparatus for detection of leak of gas
Inventor: NUKUI KAZUMITSU
IPC: G01M3/28
Filed: 1995-03-17
Abstract: PURPOSE: To provide a gas leak detection method and its apparatus by which a leak place in a gas pipe, a leak amount and a leak state can be detected precisely and quickly. CONSTITUTION: Notice is taken of a fact that, as long as a flow rate at the downstream end is identical, a restriction member (a spherical body 18) which is arranged on the upstream of a pipe generates different pressure losses according to whether a leak place on the downstream side of the restriction member exists or not. First, a pressure is measured by a pressure gage 13 in a state that a purge valve 15 has been closed. Then, the purge valve 15 is opened until the measured flow rate of a flowmeter 14 becomes a prescribed flow rate, and a pressure is measured by the pressure gage 13 in this state.  The difference between the measured pressures is regarded as a pressure loss generated by the spherical body 18, its value is compared with a pressure-loss reference value which has been found in advance in a state that a gas is not leaked, and the existence of the leak of the gas, a leak place and a leak state are judged on the basis of a compared result. The spherical body 18 is attached to the tip of a coil-shaped wire material 17 so as to be inserted, passed and arranged in an arbitrary place inside a gas supply pipe 11.

IPC: G06F19/00
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To make voting safe by escaping the preparation of the proof of voting by allowing a voter to tell a lie to a person who bribes a vote that the voter votes for another person instead of the person that the voter actually votes for. SOLUTION: A voter Vi calculates Gi=gai modp by using a random number (a)i , and enciphers a vote content (v)i into mi =E(vi ,ri )=g<vi> G<i> ri modp using a random, number (r)i . This cipher can calculate (vi ',ri ') (vi ≠vi ') that make E(vi ',ri ')=E(vi ',ri ') by using the secret key of the Vi . Also, the random number (a)i used for this encipherment is divided into (a)i1 ,..., (a)i N, and transmitted to a parameter manager. The parameter manager calculates Gij =gaij modp(j=1,..., N), and opens the Gij to the public. A collector C validates only voting mi . Gi for establishing Gi =πj1 NGi ,-j modp, and the Vi returns the (v)i , (r)i , (m)i to the collector C.  The C turns the valid voting (m)i , Gi and (v)1 ,..., (v)k into a random sequence (v)'1 ,..., (v)k ', and opens information σ that certifies that the (v)i (i=1,..., k) is the correct vote content of any of the m1 ,..., mk to the public.

Title: Transparent original reader
Inventor: MORITA HIROSHI
IPC: H04N1/04
Filed: 1993-04-13
Abstract: PURPOSE:To make an original transmissivity and the sensitivity of an original read means finely coincide and to improve the accuracy of reading original pictures at a relatively low cost by providing a dimmer circuit for adjusting the light quantity of a light source means. CONSTITUTION:The signals of a frequency f1 from an oscillator OSC 2 become the thin pulses of the period of 1/f1 in a differentiation circuit 1 constituted of a C2 and an R2 and reset an integration circuit by the period of 1/f1 by using a TR 6. When an operator adjusts a light quantity setting means, the voltage of the signal 7 changes from the voltage of the signal 8 to the voltage of the signal 9. Thus, since the input voltage of the integration circuit changes and the time for reaching to the voltage of the signal 9 changes, the duty ratio of the signals outputted from the comparator of an IC 3 changes. The output signals from the IC 3 and the signals of the frequency f2 from the OSC 1 are ANDed and outputted to the light source means, however, since the integrated value of the signals change, the light quantity of the light source means is correspondingly adjusted and a transparent original is irradiated.

Title: Heat collector utilizing natural energy
Inventor: NINAGAWA NORIO
IPC: F24S10/70
Filed: 1985-04-23
Abstract: PURPOSE:To prevent the heat-collecting function due to frosting from lowering and to enable elongating the operation time and moving at a low external air temperature by providing a gap between the ends of each of heat collecting plates. CONSTITUTION:The total of distances (b) and (c) between the bar ring 1 centers at both ends of each of heat collecting plates 2 and ends of each of the heat collecting plates 2 are made shorter than the bar ring 1 pitch P, and heat collecting pipes 4 are penetrated through the bar rings 1 to expand the same so as to hold the heat collecting plate, so that the gaps 13 between the ends of the heat collecting pipes 2 are disposed alternately in a zigzag manner in vertical and horizontal directions. Although the front surfaces of the heat collecting plates 2 are frosted, approach of frosts themselves are difficult to occur in the gaps 13 because the fin pitch is doubled therein and the gaps 13 have air permeability because they are in a hollow state. The inner wall of the hollow portion is the planar portion of the heat collecting plate and has a frost quantity which is less than that at the tip end thereof. Hence, it easily transmits the atmospheric air heat and since the area of the inner wall is larger than the sectional area of the hollow portion, the effective heat collecting area in the frosted state is increased in the latter than in the former.
