Title: Voltage-to-current converter
Inventor: TAKAGI YOSHIMI
IPC: H03F3/34
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain a voltage-to-current converter whose circuit constitution is simple, which is miniaturized and which is made inexpensive, by a method wherein a signal selection circuit in which the voltage of a primary-side rectifier and filter circuit in an input/output isolation circuit and the output of an output-current detecting element are used as input signals is inserted into a feedback-signal output circuit. SOLUTION: A voltage-to-current converter is constituted of a current detecting element 1, of a signal selection circuit 2, of resistors 2a, 2c, 2d, of a transistor 2b and of a voltage source 2e. Whether an output current exists or not is detected by the current detecting element 1, which is composed of a photocoupler which is inserted into the output part of the voltage-to-current converter. Then, when the output current is at a prescribed value or higher, a continuity state is set. When the output current is at the prescribed value or lower, an open state is set. In addition, the signal selection circuit 2 is connected to the collector of the transistor 2b via the resistance 2a so as to detect the voltage of a primary-side rectifier and filter circuit 16 in an input/ output isolation circuit.  As a result, when an output signal is normal, the voltage of the primary-side rectifier and filter circuit 16 is used as a feedback signal as it is. In an abnormality, the feedback signal is set at 0.

Title: Manufacture of semiconductor device
Inventor: SAWADA MASAMI
IPC: H01L21/266
Filed: 1990-11-20
Abstract: PURPOSE:To stabilize the breakdown strength of a diode and the withstand voltage of the diode to static electricity and to improve an irregularity between lots and between wafers by a method wherein an impurity diffused within the bounrary lines of the diode part is removed in an etching process. CONSTITUTION:A p-type epitaxial layer 2 is formed on a p<+> semiconductor substrate 1 and thereafter, an n-type well layer 10, a field oxide film 11 and a gate oxide film 15 are formed and moreover, a non-doped polycrystalline silicon film 15 is grown and an oxide film is formed on the surface of the film 15. This oxide film is formed to lines Y on the sides more outer than lines X, which are used as the boundary lines of a diode part, and after that, the silicon film 15 is etched along the lines X, whereby even if diode's parts which are extended from the lines Y to the directions of the lines X are turned into an n<++> polycrystalline silicon film by the lateral diffusion of phosphorus, these parts are removed by etching. Accordingly, an N-type impurity does not exist in the diode part. Thereby, with the breakdown strength of the diode stabilized, the withstand voltage of the diode to static electricity is also stabilized and an irregularity between lots and between wafers can be also improved.

Title: Checking method for operation of solenoid
Inventor: KAKINUMA TOSHIBUMI
IPC: F16K31/06
Filed: 1990-11-20
Abstract: PURPOSE:To securely check an operating state of solenoid ON with high reliability by detecting movement of a movable iron core based on difference in slopes on a stable region of transient current waveforms due to inductance of a coil related to a position of the movable iron core. CONSTITUTION:A waveform of transient current which flows to a coil 11 when a switch 26 is turned ON shows, as shown in the figures, (a) when a movable iron core is attracted which is a normal case, (b) when the movable iron core stops during movement and (c) when it does not operate at all, wherein slopes of the stable waveforms after the current waveform temporarily drops at the time of normal movement of the movable iron core are different. If time required for a transient current value to reach from a first set value (a value corresponding to 80% of 100% excitation current in this example) to a second set value (a value similarly corresponding to 90%) is measured, time Ta, Tc shows a relation Ta>Tb>Tc, so that measurement of the time allows a position of the movable iron core when a solenoid is turned ON to be securely detected thereby checking its operation state with high reliability.

Title: Hydrogen storage alloy composition, and electrode for nickel-hydrogen storage battery
Inventor: SHINTANI HISAFUMI
IPC: C22C19/00
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy composition excellent in corrosion resistance as well as in hydrogen occluding/releasing cycle life and increased in the amount of hydrogen occlusion and also to obtain an excellent electrode material for Ni-hydrogen storage battery, by adding hydroxides of heavy rare-earth elements or heavy rare-earth oxides having specified specific surface area to an LaNi5 hydrogen storage alloy in a specific proportion. SOLUTION: This alloy composition consists of (A) 100 pts.wt. of LaNi5 alloy and (B) 0.2-20 pts.wt. of at least one kind selected from the group consisting of hydroxides of heavy rare-earth elements and heavy rare-earth oxides having (0.1 to 10)m<2> /g specific surface area. It is preferable that the component (A) is represented by general formula R(Ni(w-x-y-z) Mnx Aly Coz ), where R means La or mixture of rare-each elements containing La and 4.0<=w<=6.0, 0<=x<=0.6, 0<y<=0.5, and 0<z<=1.0 are satisfied. It is preferable to regulate average grain size to 1-300μm. When the specific surface area of the oxides in the component (B) is smaller than 0.1m<2> /g, the effect of addition is hardly produced.  When it exceeds 10m<2> /g, the amount of elution of the oxides into an electrolyte is increased and initial activation is extremely deteriorated and the service life of a battery is shortened.

Title: Speed change control device for electronically controlled automatic transmission
Inventor: OKUBO MASAHIRO
IPC: F16H61/08
Filed: 1989-12-05
Abstract: PURPOSE:To obviate a separate reversing solenoid valve by controlling pilot pressure to a second change-over valve by one way of combination among total four ways of on-off combination of two solenoid valves in order to perform speed change into reverse. CONSTITUTION:When solenoid valves 19, 15 for the first and second gear speed are turned on by a control device 62, operating oil is fed to a brake 33 through a first and a third change-over valves 16, 20 and further through a second change-over valve 4, thus performing speed change into reverse. In the second change-over valve 4, a coil spring 71 is interposed between spools 69, 70, and the pilot pressure receiving area of the spool 70 is set larger than of the spool 69. Accordingly, even if pilot pressure is operated simultaneously to ports 4c, 4d by the wrong action of the control device 62, the spool 69 is not moved, and thereby speed change into reverse at the time of the first and second speed being selected is prevented positively. As a result, a separate reversing solenoid valve is unrequired, and therefore a space is saved.

Abstract: PURPOSE:To attain binarization processing with high picture quality by obtaining a peak of a histogram with respect to background and setting background noise cut level in the vicinity of the skirt of the peak. CONSTITUTION:A histogram (p) of a picture signal (a) at an area (o) not including a picture of an original 1 is obtained by a histogram means 24 and an area (t) of the peak is obtained. Then the area is changed into an area (q) including the original 1, a histogram means 26 obtains the histogram (r) of the area and a peak (s) with respect to the background is detected from the histogram being the exclusion of the range (t) from the histogram (r). Then the background noise cut level (b) is set in the vicinity of the skirt of the signal level including the picture in the left/right skirts of the peak (s). Thus, the background noise cut level (b) is always set properly without being affected by the picture signal to the area other than the original in the blur correction after the elimination of noise and the picture quality after binarization processing of the picture is improved.
