Title: Cylinder lock
Inventor: YASUHARA SHINKICHI
IPC: E05B29/04
Filed: 1993-11-22
Abstract: PURPOSE:To enable a key to be turned smoothly even if it is turned during insertion. CONSTITUTION:A lock piece 8 is provided in the depth of a tumbler 6. The dimension D1 of the clearance between the lock-groove engagement portion 8b of the lock piece 8 and the side of a lock groove 1a is set to be smaller than that D2 of the clearance between the lock holding portion 6b of the tumbler 6 and the side of a lock groove 1b. When a key is inserted under the action of a turning force exerted in the direction of arrow A, the lock-groove engagement portion 8b is engaged with the side of the lock groove 1a and the lock holding portion 6b of the tumbler 6 is held away from the side of the lock groove 1b. The lock holding portion 6b is therefore prevented from being hooked to the side of the lock groove 1b.

Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce power loss in a switching element, without increasing the scale of the circuit. SOLUTION: Clamp circuits 2A to 2D are composed of Schottky barrier diodes DSBD1 to DSBD4 and resistors RD1 to RD4. As a result, the waveform of drive current IB supplied to switching elements Q1 to Q4 becomes ideal, for examples, a current waveform with increased reverse current at turn-off of the switching elements Q1 to Q4. Therefore, the accumulation time t stg and a fall time tf of the switching elements Q1 to Q4 are shortened, thereby reducing power loss by the switching elements Q1 to Q4.

Title: Photomask
Inventor: ISONO KENJI
IPC: G03F1/54
Filed: 1992-10-30
Abstract: PURPOSE:To obtain a highly accurate-line width corresponding to a photomask pattern, to stabilize a photosensitive agent and to enable the patterning by providing steps on a light shielding film and a transparent substrate of a photomask in accordance with the steps of an integrated circuit. CONSTITUTION:First, the photosensitive agent is applied to a glass substrate 1 and is patterned while corresponded to the stepped parts of the integrated circuit formed on a semiconductive substrate. Next, the glass substrate 1 is etched while corresponding to the stepped parts of the integrated circuit to strip off the remaining photosensitive agent, thereby forming the glass substrate 1 having steps D1 and D2 corresponding to the steps of the integrated circuit. Then, the light shielding film 2 is formed on this glass substrate 1 to pattern the light shielding part and the transmissive part. By this process, the photomask having a shape corresponding to the steps of the integrated circuit is formed. This photomask enables the stabilized patterning of the photosensitive agent without causing the difference of the focus in the photolithography process.

Abstract: PURPOSE:To enhance the charge and discharge cycle characteristic of a metal-hydrogen alkaline storage battery by containing in a negative electrode a metal, metal oxide or-metal hydroxide one part of which becomes oxyso negative ions at negative electrode potential, and containing in an electrolyte negative ions which are stable at the elusion potential of the metal, metal oxide or metal hydroxide. CONSTITUTION:When V2O3 is actually added to a negative electrode, then negative electrode potential is shown by a segment b, VO<---> ions in the state of elusion at 10<-6>mol/l is shown by a segment c and VO<---> ions in the state of elusion at 1mol/l is shown by a segment d. When an electrolyte is at pH14, V2O3 whose elusion potential is less than the negative electrode potential b is dissolved into VO4<---> and its elusion potential is raised and when the elusion potential coincides with the negative electrode potential the VO.-shows excellent catalytic properties to prevent battery internal pressure from being raised. Then 1mol/l (segment d) is obtained and ions are generated in excess. Then AlO2<-> is added to the electrolyte and the segments c, d are raised in so that the ions balance V2O3. Ions lower than the segment are selected as ones to be added. Then O2 and the electrolyte do not leak and the charge and discharge cycle characteristic of the metal-hydrogen alkaline storage battery is enhanced.

Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a control parameter value setting device and its method for an electronically controlled internal combustion engine, which can set up optimum parameters using much less data. SOLUTION: A first and a second initial value S1 and S2 finely different are used as a control parameter value (x) so as to allow each response value y1 and y2 to be given, and when an optimum parameter value Mx can be estimated to be smaller than each initial value S1 and S2 based on the size of each response value, a specified lower limit side limiting value A is made the control pressure value (x), and when Mx can be estimated to be greater than each initial value S1 and S2, a specified upper limit side limiting value B is made the control parameter value (x), and a response value y3 corresponding to each limiting value A and B, can thereby be obtained.  When the response value y3 is better than each response value y1 and y2 corresponding to each initial value S1 and S2, the limiting value A or B is set to be the optimum control parameter value Mx, and when the response value y3 is not better than each response value y1 and y2 corresponding to each initial value S1 and S2, it is determined that the optimum control parameter Mx must be in between the limiting value A and the initial value S1, or in between the initial value S2 and the limiting value B, so that Mx is thereby obtained by means of curve approximation.

Title: Data transmitting/receiving system
Inventor: KIMURA MICHIHIRO
IPC: H04L69/40
Filed: 1988-11-21
Abstract: PURPOSE:To prevent erroneous judgment when data flow is stopped for a prescribed time or over by stopping a timing processing when the flow is stabilized by means of a flow control means. CONSTITUTION:When the freezing request of data transmission/reception is inputted from a console device 6, a freezing control means 14 requires flow stabilization to a flow control means 11, requires a timer stop to a non- communication supervising means 15, generates a data transmission freezing command, and requires the transmission to a transmission control means 13. The data transmission freezing command received by a reception control means 26 is extracted by a command extracting means 27, a timer freezing control means 24 requires the flow stabilization to a flow control means 21, requires the timer stop to a non-communication supervising means 25, and outputs a data transmission/reception freezing message to a console device 7. Thus, even when the data flow is stabilized for the arbitrary time, the non-communication fault is not generated.
