Title: Warning device
Inventor: TAKEDA HIROAKI
IPC: G03G21/00
Filed: 1984-11-19
Abstract: PURPOSE:To obtain a warning device which warns that the pulse width of a load driving signal is out of a setting range for duty conversion, by using a detection element and a warning member. CONSTITUTION:The duty ratio of an output signal OUT-C of a Q4 of a delay t time generating IC is decided by a resistance R3 and a capacitor C3, and the rise timing is synchronous with a signal OUT-A. If the duty ratio of the OUT-C is set at 20% for instance, a current iC sent from the OUT-C flows to an ICQ2 via a resistance R6, a light emitting diode LED1 and a diode D1 in case the duty ratio of a signal OUT-D is set at <=20%. Thus the LED1 emits the light. While no current flows owing to the D1 in case the duty ratio of the OUT-D is set at >=20%, and the LED1 emits no light.

Title: Method and device for manufacturing gypsum board
Inventor: SASAKI KUNITOSHI
IPC: B28B19/00
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To find immediately the cutting of an upper paper and/or a lower paper generated by foreign matters mixed in or the like and not discontinue the manufacture by expanding the interval between an upper molding machine and a lower molding machine when electric current is transmitted into an electric circuit during the manufacture of a gypsum board. SOLUTION: When an upper paper 1 is broken, an upper plate 5 and an upper electrode 7 are brought into contact with gypsum slurry 3. The gypsum slurry 3 is slurry formed of calcined gypsum with water and an electric conductor. One electric circuit, therefore, is formed between the side of the upper plate 5, an upper electrode 7 and an electric current sensor 9, and an air cylinder 10 is actuated by the electric current sensor 9 to lift the upper plate 5 to the dot-line position. A clearance between the upper plate 5 and the lower plate 6 is enlarged and foreign matters caught on the plates can be passed through easily between the plates 5 and 6 to eliminate the cause of conduction, for example, paper cutting and not breaking the upper paper 1 and/or the lower paper 2 any more.

Title: Interruption control system
Inventor: HAYAKAWA TOSHIYUKI
IPC: G06F9/46
Filed: 1984-11-19
Abstract: PURPOSE:To reduce the generation of overruns by replacing a counter of a microprogram for each generation of the overrun of a sector and setting again the set sector position through a set sector processing part. CONSTITUTION:When a controller 2 receives an instruction to give an access to a disk 3 for read or write from an upper device 1, a microprogram 4 of the controller 2 decides the address of a desired sector and sets a set sector number (n-2) for interruption of rotational position sensing RPS. The set sector number is temporarily separated from the device 1. Then the RPS interruption is produced when the position of the set sector is detected. If the time during which the transfer of data equal to a sector is through between the device 1 and the controller 2 is larger than the time needed to travel two sectors, a sector overrun is produced. Thus a counter 5 of the program 4 is replaced. When the count value of the counter 5 exceeds the prescribed value, a set sector processing part 6 sets again the set sector position. Thus the generation of overruns can be reduced.

IPC: G01N27/327
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To early stabilize the output of a sensor by allowing a microbial membrane to stand in a specified temperature range for a specified time prior to the mounting on the sensor, and adding a microorganism growth inhibitor to a buffer solution. SOLUTION: A mixed solution containing dissolved oxygen laid in saturated state, which is prepared according to the program of a control part 14, is passed to a heat exchanger 9 in a thermostat chamber 8 to keep a set temperature, and then sent to a microbial sensor 10. The electric signal of the microbial sensor 10 according to the dissolved oxygen quantity consumed for assimilation of the organic matter in the sent solution by the microorganism is outputted by the microorganism in a microbial membrane 12 and a dissolved oxygen electrode 11. Since the consumed dissolved oxygen quantity has a proportional relation with the organic matter quantity in the measuring solution, a calibration curve is preliminarily formed from the measurement of a reference solution 1 having a known BOD concentration.  The electric signal output of the measurement of test water 3 is arithmetically compared with this by the control part 14 to calculate the BOD concentration in the test water 3, and a series of data is displayed on a display part 15 and printed out to a recorder 16.

CONSTITUTION:A transistor and the like are formed through ordinary steps. A wiring hole 4 is formed in an intermediate insulating film 3 comprising PSG on the transistor and the like. Metal silicide 5 is further evaporated. The range of ions is set at an interface between the silicide 5 and the intermediate film 3 for a diffused layer 6 at a wiring hole part. Ions are implanted 7. Mixed layers 8 of both layers are grown at the interface. The ions are implanted into the diffused layer 6, too. Annealing is performed in order to recover the crystal deffect caused by the ion implantation. Thereafter, an Al-Si layer comprising lower wiring material is sputtered, and wiring is performed. In the obtained wiring, the metal silicide film is not released even if adhesive tape is stuck and removed. Therefore adhesion is improved. As the ions for said ion implantation, Si and Ge among B, Si, P, Ga, Ge and As or the ions indicating the same conductivity as that of the diffused layer are used.

In the case of reading a signal, the digital video signal 11 written before 1H from the head of 1H is read at a period being twice a write period. In the case of receiving a progressive signal, a selector circuit 14 selects the digital video signal 11. Thus, the inter-line signal is generated with a memory capacity as small as 1H and the circuit is made small.

IPC: G06F17/50
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To suppress stray inductance by the use of component characteristics by providing a new ground symbol on a circuit diagram, and arranging a through hole which connects to an internal-layer ground by the land pattern of the ground of a component connected to the symbol on the circuit diagram at the same time with component arrangement. SOLUTION: When a substrate pattern is generated by using a circuit diagram input CAD system and its net output, the new ground symbol mark (e.g. black- painted thick arrow) 2 which is different from a conventional ground symbol mark 1 indicating the ground of a capacitor C3 is introduced. Then the through hole 4 for component ground connection is arranged at the same time nearby the component land indicated with the new ground symbol mark 2 and the length of the ground pattern 5 of each component is shortened. Consequently, the influence of the difference in high-frequency characteristics between an original circuit diagram and an actual circuit, i.e., stray inductance generated at the time of substrate mounting can be checked at the original circuit diagram level.
