Title: Wood preservative, wood preserved against decay and improvement of wood
Inventor: INOUE TADAMORO
IPC: A01N55/08
Filed: 1992-12-02
Abstract: PURPOSE:To preserve wood against decay by impregnating wood with a compd. prepared by chelating chito-oligosaccharide, 2,5-anhydromannose and chitosan reduced in mol.wt. with boric acid. CONSTITUTION:Chitosan with a reduced mol.wt. of 320-48000, chito- oligosaccharide with a mol.wt. of 320-3200 and heterosaccharide of 2,5- anhydromannose are chelated with boric acid to prepare a liquid or powdery substance which is, in turn, infiltrated in wood and the impregnated wood is dried by alcohols. By this method, chitosan with a reduced mol.wt., chito- oligosaccharide and 2,5-anhydromannose are fixed in cells of wood. When boric acid fixed in the cells of wood is a concn. of 0.8%, the propagation of putrefactive bacteria is inhibited and, in the case of 0.8% or more, control effect on a cockroach or a white ant is obtained. Boric acid is low in toxity and wood preserved against decay harmless to a human body can be obtained.

Title: Dc-to-dc converter
Inventor: USUI HIROSHI
IPC: H02M3/335
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a DC-to-DC converter with plural outputs, which can precisely adjust plural output voltages, whose power loss is less and whose efficiency is high. SOLUTION: In a DC-to-DC converter, a primary winding 31a of an auxiliary transformer 31 is connected in parallel to a secondary winding wire 4a of a transformer 4, AC voltage generated in a secondary winding core 31b of the auxiliary transformer 31 is rectified/smoothed by a second rectifying/smoothing circuit 16, and a DC output voltage V02 is extracted between a second DC output terminal 17 and a 0 V output terminal 8. Since voltage per turn in the secondary winding wire 31b of the auxiliary transformer 31 becomes small, the DC output voltage V02 outputted from the secondary winding wire 31b of the auxiliary transformer 31 via the second rectification/smoothing circuit 16 can be adjusted precisely.  Since the output voltage adjusting means of a dropper circuit generating enormous power loss is eliminated, the power loss of the DC-to-DC converter with plural outputs can be reduced and efficiency can be improved.

Title: Detecting method for abnormal epithelial cell separation
Inventor: TADA MASAHIRO
IPC: A61B10/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To detect the separation rate of abnormal epithelial cell in vivo by labeling the mature surface epithelial cell in a target region, and after that monitoring the presence or absence of a label in the region. SOLUTION: This is a method of detecting the abnormal cell separation rate of a mature surface epithelial cell of a race mixture animal in vivo, in which the mature surface epithelial cell in a target region of a race mixture animal is labeled, and subsequently to the labeling process, the region is monitored concerning the presence or absence of a label. In this case, the cell is labeled by cyanine dye, and the cyanine dye is expressed by the formula. In the formula, Y indicates oxygen, sulfur, methylene or alkyl-substituted methylene, m is 0-3, and n is 12-22. Thus, a morbid state characterized by the existence of abnormal cell separation in the mature epithelial cell can be diagnosed in vivo.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To realize a structure capable of outputting the information concerning prize ball and ball dispensing to the outside of a game machine at a low cost and effectively prevent the input of an illicit signal. SOLUTION: The information signal outputted from the I/O port 57 of a main board is outputted through amplifier circuits 64a-64h or a photocoupler 642. As the amplifier circuits 64a-64h, for example, a communicative end directional buffer circuit also having the amplifying effect can be used. In this case, no signal is inputted from the outside of the main board 31 through an information output circuit 64. Since the photocoupler 642 transmits the signal only in one direction, the input of signal to the main board 31 can be more effectively prevented. Accordingly, the room for the input of the illicit signal to the main board 31 through the information output circuit 64 can be eliminated.

Title: Stuck state escaping device
Inventor: SUGA YASUSHI
IPC: B60L50/16
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To escape easily from a stuck state regardless of the driving technique of a driver. SOLUTION: When the vehicle speed V is less than the threshold VES continuously for the specified time in spite of depressing an accelerator pedal, it is so judged that a vehicle fell into an unoperatable state by normal operation (stuck state) such as a wheel being caught into a recess (S102-S114). Upon judging the vehicle to have fallen into the stuck state, the torque of an assist motor fitted to a driving shaft is made the value corresponding to the depressed quantity of the accelerator pedal when the vehicle speed V is the value 0 or more (step S118) and made the value 0 when the vehicle speed is less than the value 0 (step S120). With this control, the vehicle is longitudinally shaken and escapes from the stuck state when the energy of this shaking exceeds the energy of escaping from the recess.  As a result, anyone can easily make the vehicle escape from the stuck state regardless of driving technique.

Title: Cap
Inventor: NISHIDA RYUHEI
IPC: B65D47/06
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a cap in which even a fluid of high viscosity is not left in the vicinity of a discharge outlet and the fluid does not flow out even when a container is inverted. SOLUTION: When the container 12 is pressed, the pressure inside the container 12 is increased to lift a blocking plate 28 and a disk plate 40 along a guide pin 26. Thus a flow path 42 guiding from a mouth section 12A to a discharge section 36 is set to communicate with the container, and a fluid 14 in the container 12 passes through a hole section 40A and the flow path 42 and guided to the discharge section 36. The fluid 14, therefore, can flow out of the discharge section 36.  Then, when the press force to the container 12 is released to reduce the pressure inside the container 12, the blocking plate 28 and the disk plate section 40 are lowered by the energizing force of the spring 34, and when the disk plate section 40 is brought into contact with a stopper 20, the flow path 42 from the hole section 40A to the discharge section 36 is blocked, and the interior of the container 12 is closed. The fluid 14, therefore, does not flow out unless the container 12 is pressed even when the container 12 is inverted.
