Title: Residual powder detector and image forming device provided with the same
Inventor: IWATA SHIGETAKA
IPC: G03G15/08
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce an erroneous detection at a low cost by providing a supporting shaft and a movable member, in a power container and a detecting means for detecting the pendulum motion of an operating member. SOLUTION: When the powder container 101 is reciprocated in the directions A and A', the movable member 104 in the powder container 101 swings on the supporting shaft 103 right and left in the figure, like a pendulum. After that, when the movement of the container 101 is stopped and the quantity of the powder 102 in the container 101 is small as shown by the top end surface B, the movable member 104 continuously swings only by some time. On the other hand, when the quantity of the powder 102 in the container 101 is sufficiently large as shown by the top end surface C, the movable member 104 receives the resistance of the powder 102, to be immediately stopped. Thus, immediately after the movement of the powder container 101 is stopped, the pendulum motion state of the movable member 104 is changed by the residual powder 102.  The pendulum motion of the movable member 104 is detected to detect the fact that the powder is sufficiently exists or not in the container 101.

Title: Retrieving method using phrase index for information retrieving system
Inventor: KASUGAI MIKIZO
IPC: G06F17/30
Filed: 1989-10-11
Abstract: PURPOSE:To shorten the scanning time of the real data and to improve the character retrieving speed by selecting the candidate real data via a character index and a phrase index. CONSTITUTION:When the information is retrieved, a phrase produced from combination of characters included in a character string is extracted. Then the key value corresponding to the phrase is obtained, and an AND is obtained between the same position bits of a bit train corresponding to plural key values of a phrase index. Thus a data number shown by an on-bit is obtained and the data including a phrase of a character string is retrieved as the retrieving conditions. That is, the combination of the prescribed characters in expressed in an AND of several keys. Thus the total number of keys can be cut down to several thousands even though the permutations and combinations of optional two characters, for example, among several thousands of characters used in the Japanese sentences reach a large number, i.e., several ten millions. As a result, the retrieving time can be shortened in terms of combinations of characters.

Title: Artificial gullet
Inventor: SHIMIZU YOSHIHIKO
IPC: A61F2/04
Filed: 1988-10-19
Abstract: PURPOSE:To accelerate the regeneration of the esophagoepithelium of an accident by intrusion of cells into a collagen layer and to slip down a silicone tube in a relatively late period so as not to remain in the gullet by using the artificial gullet formed with the coating layer of collagen on the outside surface of the silicone tube. CONSTITUTION:The silicone tube is put into, for example, a glass tube in order to form the collagen coating layer on the outside surface of the silicone tube. A 1% solubilized collagen soln. (pH3.0) stirred for one hour under the condition of 3,000rpm is poured between the silicone tube and the glass tube and is frozen at -20 deg.C. After this soln. is vacuum dried, the dried collagen is heat treated for 24 hours at 105 deg.C in a vacuum. The artificial gullet is thereby produced. The cells, therefore, infilter the inside of the collagen layer in the early period after an operation and propagate actively to regenerate the tissue, thereby accelerating epithelization. Since the collagen layer alone has no cavity holding power in the gullet, the silicone tube maintains the physical strength before a wound treatment is completed. The silicone tube slips down after the completion and does not remain therein. Foreign matter which is the cause for granulation or inflammation does not, therefore, exist any more.

IPC: H01L21/31
Filed: 1987-10-20
Abstract: PURPOSE:To form a film with good reproducibility by providing a discharge amount control line in a discharge line in case of switching a reaction gas supply line to a purge gas supply line, thereby setting the gas discharge amount and gas conditions of a step of extracting gas in a reaction tube of previous step of vapor growth to the same as those of the step of vapor growth. CONSTITUTION:In purge gas lines 3, 3A, 3B, purge gases 2 controlled by flowrate controllers 1 flow to a reaction tube 5 which is reduced under pressure by a gas discharge system 4, and is discharged through a discharge line 6 to a discharge (I). In this case, in the first purge, the pressure is high due to a large quantity of purge gas flowing from two systems, is then reduced in quantity to one system, discharge amount is further suppressed by the operation of a discharge control line, and regulated substantially to the same conditions as those of a step of vapor growth. Then, the purge line is turned OFF, the gas in the tube is extracted, but since the pressure is reduced in the second purge, the time of gas extraction is shortened, and pressure change due to the introduction of reaction gas is reduced, thereby forming a film with good reproducibility.
