Abstract: PURPOSE:To prevent the operation of a magnetic memory device due to the occurrence of alarm start during transportation from occurring and to prevent the device from being damaged by stopping power supply to the magnetic memory device incorporated in electronic equipment when a power source part is comprised of a battery and also, a display part is closed. CONSTITUTION:A display part opening/closing detecting part 18 detects the opening/closing state of the display part 5, and outputs a display opening/closing signal 104 of low level when it is closed and the one of high level when it is opened. A power source control part 21 turns on power control signals 106, 107 by the pulse of an on/off signal 102 when no logic power source 17 is supplied from a DC/DC converter 15a, and turns it off when it is supplied. The DC/DC converter 15a is controlled by the power source control signals 106, 107. When DC is supplied from the battery 4 or an AC adaptor 6, a logic power source 16a is always outputted, and the logic power source 17 is outputted when the signal 106 is turned on, and a power source 19 for magnetic memory device is outputted when the signal 107 is turned on.

Title: Anti-skid control device
Inventor: ARIKAWA TETSUO
IPC: B60T8/58
Filed: 1982-07-26
Abstract: PURPOSE:To control the brake pressure so as to be at the optimum level at all times by changing the times for releasing the brake or holding it constant specified on the basis of No.2 decelerative signal generated when the wheel deceleration has exceeded the reference value for No.2 deceleration which is higher than No.1 deceleration reference value. CONSTITUTION:When the wheel deceleration of a brake time differential device 5 has exceeded No.1 deceleration reference value, No.1 deceleration signal generator 6 emits No.1 deceleration signal. An exhaust valve solenoid 25 is energized during No.1 specific period determined by No.1 ON delay timer 13, to cause drop of the brake pressure and thereafter, i.e. during No.2 specific period determined by No.2 ON delay timer 15, the brake pressure is held constant. If, however, the deceleration exceeds No.2 deceleration reference value within No.1 specific period, No.2 deceleration signal generator 7 emits No.2 deceleration signal. After passage of No.3 specific period determined by No.3 ON delay timer 14, said solenoid 25 is put out of energization, and the brake pressure is held constant. Then after passage of No.4 specific period determined by No.4 ON delay timer 16, the brake pressure drops again.

Title: Solder paste
Inventor: UEDA HIDEFUMI
IPC: H05K3/34
Filed: 1994-06-13
Abstract: PURPOSE:To obtain an activator which has high activity and good preservable stability as solder paste by using halogenated org. acid, such as fluorobenzoic acid, as an activator to be included in a flux vehicle constituting the solder paste. CONSTITUTION:Although decomposing of an amine halogenated hydro acid salt to an amine and hydrochloric acid by heating is effective as the activator at the time of soldering, such decomposition is the cause for indication of corrosiveness and, therefore, the halogenated org. acid is used as the activator which effectively acts without being decomposed as it is. The halogenated org. acid is at least one of a fluorobenzoic acid, chlorobenzoic acid and bromobenzoic acid and the content of the halogenated org. acid into the flux vehicle is specified to 0.5 to 10%. Such halogenated org. acid exists without ionization of halogen in the paste and acts as the activator as it is.

Title: Speaking current control circuit
Inventor: KIKUI HIDEKI
IPC: H04Q3/42
Filed: 1991-06-03
Abstract: PURPOSE:To prevent audible noise from being generated when a subscriber circuit moves the state between the limited state of a speaking current and a limit cancel state. CONSTITUTION:A voltage not to limit the speaking current is impressed to the non-inverted input of an input side voltage follower circuit 3 and with the output, a capacitor C for charging and discharging is charged through a resistor R0. Therefore, an output side voltage follower circuit 4 outputs the voltage not to limit the speaking current, and the speaking current of a subscriber circuit 2 is turned to the limit cancel state. When a base current flows to a transistor Q0 for limiting the speaking current, the capacitor C is discharged at a time constant R1.C through a resistor R1, the output of the output side voltage follower circuit 4 is switched by this time constant as well, and the speaking current is also turned to the limited state by this time constant. When the base current of the transistor Q0 is turned to zero, the capacitor C is charged with a time constant R0.C, and the speaking current is turned to the limit cancel state by this time constant as well. Therefore, there is no rapid change in the speaking current, and no audible noise is generated.

Title: Treatment of condensed water
Inventor: ITO TOMOAKI
IPC: B01J47/12
Filed: 1990-05-22
Abstract: PURPOSE:To enable long-time filtration and to obtain treated water contg. a small amt. of clad leakage by using a highly acidic cation exchange resin having a specified degree of cross-linking with divinylbenzene. CONSTITUTION:When a precoat layer 13 of a filter aid obtd. by mixing a powdery highly acidic cation exchange resin with a powdery highly basic anion exchange resin is formed on the surface of a filter element, the degree of cross- linking of the cation exchange resin with divinylbenzene is regulated to 2-7.5%. Since a precoat layer 13 having large void volume and extremely superior compression resistance can be formed, compacting phenomenon of the layer 13 during passage of water is minimized, filtration time is prolonged and the amt. of clad leakage especially in the early stage of passage of water can drastically be reduced.

Title: Dc stabilizing power unit
Inventor: YAMAMOTO SHOICHI
IPC: G05F1/56
Filed: 1990-05-21
Abstract: PURPOSE:To prevent the voltage above the set value from appearing in making and breaking input power source by further connecting a transistor to the base of a transistor, and further adding a transistor for controlling the transistor. CONSTITUTION:Whatever condition the transistor Q2 is in, if a transistor Q3 is put in on condition, the impedance value of a transistor Q1 can be made infinite, that is, output voltage can be made zero. The base voltage e2 of a transistor Q4 is made to rise enough later than the rise of the voltage VcI of a capacitor C1 for smoothing. By doing it this way, output voltage Vout settles to zero immediately at the point of time of the turn-off of the transistor Q4, and the voltage higher than the set voltage never appear in output terminals under any condition.

Title: Mechanical ignition type sensor
Inventor: AMANO HIROATSU
IPC: B60R21/16
Filed: 1995-05-29
Abstract: PURPOSE: To provide a mechanical ignition type sensor which can set dimension al tolerances of respective component parts large while operational sensitivity is being maintained as specified, and also can reduce its cost. CONSTITUTION: In a mechanical ignition type sensor 10, a slide hold section 42 and a projected section 43 are formed in a trigger lever 36. The projected section 43 is engaged with the inner circumferential periphery of a trigger groove 44 for an inertial mass body 32 so as to be formed into a condition where the slide hold section 42 is brought into contact with the inertial mass body 32. This constitution thereby allows the slide hold section 42 (specified engaging margin f) to be determined by a forming position of the projected section 43, and also prevents the slide hold section 42 from being affected by scattering of dimension for each component part of the sensor.  Therefore, even if a dimensional tolerance of each component part for the sensor is not strictly set, its operation sensitivity can be maintained as specified by accurately setting only the forming position (dimension) for the projected section 43 of the trigger lever 36, and its cost can thereby be reduced.
