Title: Combustion control device for bath boiler
Inventor: KONISHI MITSUNARI
IPC: F23N5/02
Filed: 1983-07-11
Abstract: PURPOSE:To prevent danger due to the trouble of a temperature sensor, no-water burning or the like and improve the safety of the boiler by a method wherein D.C. electric source is controlled by an abnormality detecting circuit, a hot-water temperature detecting circuit, a forced combustion circuit, a boil-up stopping circuit and a changeover switch. CONSTITUTION:The changeover switch 13, the abnormality detecting circuit 14, the hot-water temperature detecting circuit 15, the forced combustion circuit 16, the boil-up stopping circuit 17 and a hot-water temperature regulating volume 18 are accommodated in a controller 1. When the changeover switch is switched to 'automatic operation', the D.C. electric source 10 is given to the hot-water temperature detecting circuit 15 through the abnormality detecting circuit 14 and a set temperature is compared with hot-water temperature by a signal from a sensor 2 and when the hot-water temperature is higher than the set temperature, the D.C. electric source is given to an ignition sequence circuit 11 to continue the combustion of the boiler. When the set temperature is lower than the hot-water temperature, the electric source is cut by the hot-water temperature detecting circuit 15 and the combustion of the boiler is stopped.

Title: Color burst reinserting circuit
Inventor: MINAMI NORIAKI
IPC: H04N9/455
Filed: 1983-07-11
Abstract: PURPOSE:To prevent a discoloring phenomenon which is produced when a normal reproduction is shifted to a special reproduction and vice versa, by using the coincidence/detecting signal of a phase wave detecting circuit to control an internal color burst production block. CONSTITUTION:A PAL system video tape recorder contains an internal color burst production block 12', a burst sequence continuation block 21' and a color burst insertion block 22. For a color burst reinserting circuit of the video tape recorder, the reproduced color signal supplied froma terminal 2 is applied to a phase wave detection circuit 17 together with the reference signal supplied from a terminal 3. The coincidence/discordance detection signal of the circuit 17 is used to control the block 12' to the discordance of the burst sequence in case a normal reproduction is switched to a special reproduction. Thus the coincidence is obtained between the sequence of the internal color burst and the burst sequence of the reproduced color signal in a normal reproduction mode.

Title: Dental instrument with illuminating mechanism
Inventor: YAMASHITA SEIICHIRO
IPC: A61C1/08
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To achieve a desired illuminating function without using light guides in a dental instrument equipped with an illuminating mechanism.

Title: Hot-water supplier
Inventor: KAWASHIMA HIROFUMI
IPC: F24H1/10
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To let hot water reach the set temperature in a short time by starting the combustion of a burner and heating the water of a heat exchanger in case that a quantity-of-water sensor does not detect the flow of water supply, and heating the hot water in the water passage through a heat exchanger at all times. SOLUTION: Water passes a water temperature sensor 1, and a quantity-of- water sensor 2, and is divided into two courses downstream of it, and the water of one water passage M absorbs the heat of a burner 9 with a heater exchanger 3, and passes a hot-water supply sensor 4. The water of the other bypass passage S passes a hot-water supply sensor 5, and is discharged from a hot-water discharge port. At this time, a principal solenoid valve 7 for gas, a proportional valve 8 for gas, a fan 10 for combustion air are driven so that it may come to the set temperature at the time of combustion of the burner 9 by means of a quantity-of-combustion control means 12.  In case that the quantity-of-water sensor 2 is not detecting the flow of water supply by the combustion deciding means 11, when the temperature of the hot-water flow sensor 4 goes down under a certain temperature, the combustion of the burner 9 is started, and when it goes higher than a certain temperature, the burner 9 is stopped.

Title: Plant-growing method at damshore
Inventor: IIZUKA OSAMU
IPC: E02B3/12
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent planting materials from being washed away and to improve percentage of taking roots for plants by a method wherein cultural seedlings of field horsetails of scouring rush family are planted on a damshore and piles in a square column shape or a circular column shape in a specified length and thickness are driven into earth around roots of the cultural seedlings. SOLUTION: Cultural seedlings of field horsetails of scouring rush family are planted on a damshore, and piles each in a square column shape or a circular column shape in the length of 30-50cm and in the thickness of 1-3cm are driven into earth around the cultural seedlings. The pile in the length less than 30cm is too short and is liable to be removed because of unsteadiness of cleyey soil or stone gravels at a side slope. In case of the pile in the length more than 50cm, the pile is liable to be broken while workability is becoming extremely bad because stones or gravels become extremely abundant in a depth exceeding 20cm at a side slope of a dam even though the surface is covered with soft cleyey soil. On driving the pile into earth, the upper end of the pile is set 1-2cm below the ground surface.  Thereby, percentage of taking roots can be improved for the seedlings of field horsetails, and erosion at the damshore or the like can be prevented.

Abstract: NEW MATERIAL: Modified calcitonin composed of des-17-histidine calcitonin.  
     USE: A high titer blood calcium regulating agent.  
     PROCESS: For example, Boc-L-proline (Boc is t-butyloxycarbonyl) is reacted with a benzhydrylamine resin (BHA resin) in the presence of a condensation agent by using a peptide synthesizing device and an amino protective group is subsequently removed to obtain an Lproline resin which is, in turn, reacted with amino acid wherein an α-amino group and a side chain functional group are protected according to an anaino acid sequence of polypeptide and an amino protective group is subsequently removed. This operation is repeated to synthesize a polypeptide chain which is, in turn, treated with HF to perform the elimination of peptide from the resin and the removal of all of protective groups and, if necessary, a disulfide bond is formed in a molecule by a usual method to obtain des-17-histidine calcitonin.
