Title: Carrying article monitoring device
Inventor: KURIHARA JIRO
IPC: G21C17/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To improve the operating safety of a device by providing the device with a detector drive arithmetic part for regulating the setting height of an upper detector by each of front and rear regulating maximum information values and a reserve signal. SOLUTION: An information partitioning function 11 divides the periodic information of the height dimension measured by height detectors 1, 2 into a plurality of sections in time series from a front part section to a rear part section as A→B, B→C, C→D, D→X. Each of front and rear information selecting functions 12, 13 selects the maximum information values in the front section and rear section, respectively, to set a front maximum information value and a rear maximum information value. The front and rear maximum information values are mutually compared by a maximum information value comparing function 14, and when the rear value is larger than the front value, a reserve signal is outputted. A detector drive arithmetic part 3 regulates the setting height of an upper detector 6 by both the maximum information values and the reserve signal.  Therefore, the contact of the detector 6 with a carrying article 18 can be avoided, and the operating safety of a carrying article monitoring device can be improved.

Title: Solenoid pump
Inventor: HASHIMOTO TSUNEO
IPC: F04B17/04
Filed: 1979-04-24
Abstract: PURPOSE: To raise the efficiency of pump as well as stabilize the working of piston by utilizing all of input as exciting current flowed from AC power source as working power by a method in which initial working power is given to piston by the magnetic force of a permanent magnet and held in it.  
     CONSTITUTION: During a half cycle, the piston 13 is positively moved in one direction of moving stroke by means of a working force, or the sum of an initial working force of the permanent magnet 5 plus a magnetic force of the excited coil 2, and then during the remaining half cycle, an initial working force of the parmanent magnet 5 is neutralized with a magnetic force of the excited coil 2. And the piston 13 is moved in the other direction of the moving stroke by the repulsive force of the compressed spring 15 on a pressurized side and a liquid sucked on the inlet 6 side is discharged to the outlet 7 side by a reciprocating movement of the piston 13. Thus, because all of input can be utilized as working force, a very high efficiency of working force can be continuously obtained and therefore a highly stabilized reciprocating movement of the piston 13 is made possible.

Abstract: PURPOSE:To extremely inexpensively and compactly mount to a picture processor by designating the required spot of an original picture on a coordinate plane based on a coordinate position signal inputted by a digitizer and a detected result detected by a coordinate axis changing quantity detecting means. CONSTITUTION:When a designated area P on an original 5 is more than the area of a digitizer 2, two points P1 and P2 of the four vertexes of a rectangle, which exist in the area of the digitizer 2, are pointed with a signal detecting pen 4 first. Next, an original guiding board 3 is moved in a condition in which the original 5 is mounted so that the position of the other two points P3 and P4 which do not exist on the digitizer 2 may come to the area of the digitizer 2. Thus, the P3 and P4, which are the other vertexes of the designated area P of the rectangle, are pointed with the signal detecting pen 4. Thus, an arithmetic processing based on X and Y coordinate signals outputted from the digitizer 2 and the moving quantity of the original guiding board 3 is executed, the coordinate position of the original which is larger size than the size of the digitizer is inputted, and a data input device can be obtained at a low cost.

Title: Fluidized bed combustion equipment provided with load regulating function and optimum fluidizing function
Inventor: SUZUKI KAZUHIKO
IPC: F23C10/14
Filed: 1981-04-04
Abstract: PURPOSE:To realize favorable fluidized state to establish large turn down ratio and as well as contrive sharp cost reduction by a structure wherein an air dispersion plate equipped at the lower end of a fluidized bed combustion chamber is arranged at the central part of said lower end with the fixed distance apart from a vertical peripheral water-cooled wall of the fluidized bed combustion chamber. CONSTITUTION:The tubular fluidized bed combustion chamber 8 is formed by the water-cooled wall composed of a large number of straight water pipes 7 vertically arranged surrounding a fluidized bed 6. The air dispersion plate 10 is arranged at the lower part of the fluidized bed 6 with the fixed distance apart from said water-cooled wall. Owing to the structure as described above, the bending part of water-cooled wall and the installation of refractory material become unnecessary at all. Furthermore, the area of the air dispersion plate 10 is rendered to be smaller than the cross-sectional area at the lower part of the fluidized bed combustion chamber. The air dispersion plate 10 is located at the central part of the bottom of the fluidized bed combustion chamber so as to form a fluidizing zone 11 and a stationary zone 12. The inclination angle of the boundary 13 between the fluidizing zone 11 and the stationary zone 12 is so constituted as to be changed in accordance with the change of load. In other words, the fluidizing zone 11 and the stationary zone 12 can be changed in accordance with the change of combustion load so as to realize spontaneous fluidizing state by changing the inclination angle of the boundary 13 between the fluidizing zone 11 and the stationary zone 12.

Title: Character broadcast receiver
Inventor: TAKEGAMI SHIGERU
IPC: H04N7/088
Filed: 1984-03-19
Abstract: PURPOSE:To obtain a reception mode suited to each reception system by detecting automatically any character broadcast system in a channel selection mode as well as in an application mode of power supply with no transmission of a special discriminating signal for the character broadcast system. CONSTITUTION:The discrimination between VBI and a video signal period is performed by V-wind, i.e., a signal that inhibits a display excepting for the video signal period. The character broadcast of an FF system is decided if FCD detects the state of logical ''1'' in the video signal period. Otherwise the character broadcast of a VBI system is decided. Then a reset pulse RES is produced to clear registers, and the character broadcast system is decided from V-sync, i.e., the first vertical synchronizing signal delivered next. While the FC which is designated by the character broadcast to be received is written to an FC buffer 2 immediately after the RES is produced. A digital signal multiplexed to a video signal is extracted and then shifted to a shift register 1 as a packet data. This shifted data is compared with the contents of the buffer 2 by an FC comparator 3. If the FC coincidence is obtained, logical ''1'' is latched by a latch 4. While logic ''0'' is latched by the latch 4 if no coincidence is obtained. The output of the latch 4 is turned into FCD.

IPC: H01L21/306
Filed: 1990-03-01
Abstract: PURPOSE:To prevent the contamination of a semiconductor production process line and to improve the ease of use by using a semiconductor as a material. CONSTITUTION:The etching in an etching stage is executed by housing a silicon substrate in a jig 20, using the electrode consisting of the pure semiconductor as the reference electrode 22, setting a platinum plate 21 as a counter electrode, filling an anisotropic etching soln. 30 in a cell and setting the soln. at a prescribed temp. The respective electrodes are connected to a potentiostat 23 and a prescribed voltage is impressed thereto. An etching stop experiment with good reproducibility is made in this way and the infiltration of an alkaline metal into the silicon process is obviated. Contamination does not arise and the process compatibility improves. Since the voltage is generated by the actual elution of the semiconductor, the influence of a change in the etching soln. and a temp. change on the etching is reflected in the generated potential and the adequate potential is automatically generated. The semiconductors similar to actually used semiconductors are easily utilizable.

IPC: G01J5/12
Filed: 1989-03-02
Abstract: PURPOSE:To detect accurately only a specified moving object without causing a malfunction by detecting that signals from a plurality of sensors have a prescribed time difference between them. CONSTITUTION:Outputs of infrared sensors 2a and 2b are digitized to be signals S1 and S2 by A/D converters 4a and 4b. The signals S1 and S2 are turned to be signals only in a prescribed frequency band by digital filters DF1 and DF2. Next, a cross-correlation determining means CCP computes a cross- correlation value of the signals passing through the filters DF1 and DF2 by using a prescribed cross-correlation formula and determines whether or not the cross-correlation value has a peak of a value being a prescribed value Lth or above found between the upper limit Tmax and the lower limit Tmin of a time difference Tr. When the cross-correlation value has the peak being the prescribed value Lth or above found between the upper limit Tmax and the lower limit Tmin of the time difference Tr, a detection signal is transmitted to an output timer TMR and a detection output is delivered for a prescribed time. According to this method, only a specified moving body can be detected accurately.
