Title: Fore and aft grip force estimating device of vehicle
Inventor: YAMAMOTO OSAMU
IPC: F02D45/00
Filed: 1994-11-18
Abstract: PURPOSE: To estimate correct fore and aft grip force even if a vehicle is in the ascending state by comparing a first fore and aft grip force calculated from the car body speed with a second fore and aft grip force calculated from engine torque through the driving wheel torque, and selecting the larger one of the above forces as the fore and aft grip force. CONSTITUTION: First, in a first fore and aft grip force calculating means M1, the car body speed is time-differentiated to obtain a first fore and aft grip force as the car body fore and aft acceleration. Subsequently, in an engine torque calculating means M2, according to the engine rotating speed and the throttle opening, the engine torque is map-retrieved. In a driving torque calculating means M3, the engine torque is multiplied by a gear ratio corresponding to the shift position to calculate the driving torque. In the second fore and aft grip force calculating means M3, the driving torque is divided by the radius of a driving wheel and the load of the driving wheel to calculate the second fore and aft grip force. The higher one of both grip forces is selected by a high select means M5.

Title: Pulse charge type electric precipitator
Inventor: TERAI HIROSHI
IPC: H03K3/53
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To generate a proper pulse wave form without repeated sparking while using a rotary spark gap though its rotational speed is low by a method in which charge accumulated in the electrode of a precipitator is recovered temporarily to a recovery capacitor without back-flowing to a powder source. SOLUTION: A timing control means CNT brings a thyristor S into a non- conductive state immediately before the time t1 . At the time t1 , when a switch SW is turned on the side of a fixed contact point T1 , a voltage exchange is carried out between an accumulation capacitor CS and a dust collecting capacitor CEP. At the time t2 , the backflow of current is hindered by a diode D1 . After the time t2 , the current passes only through an LC resonance circuit I2 , and a voltage exchange takes place between the dust collecting capacitor CEP and a recovery capacitor CR. At the time t4 , when the switch SW is turned on the side of a fixed contact point T2 , the charge of CR is transferred to CS. After the time t1 +T3 , the thyristor S1 is brought into a conductive state, and CS is charged to return to the state of the time t1 .

Title: Power unit
Inventor: OTAKE MASAKI
IPC: H02M3/28
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a power unit which protects a load from overvoltage by immediately causing a required voltage drop when an overvoltage occurs, regardless of the magnitude of the load and, at the same time, can quickly stop its power output upon detecting that the voltage has dropped. SOLUTION: A power unit detects a load current by means of a load current detecting circuit 7 and sets the operational parameters of a switching circuit 2, for example, the maximum allowable duty of a main switching element in accordance with the detected load current. Therefore, when an overvoltage occurs in the DC output of the power unit and a short-circuiting circuit 17 works to short-circuit the DC output, a sufficient voltage drop is obtained regardless of the value of the load current, and a low-voltage detecting circuit 6 can stop the oscillation of the switching circuit 2 through a control section 9 upon detecting that the voltage of the DC output has dropped.

IPC: H01L21/3065
Filed: 1992-10-23
Abstract: PURPOSE:To provide a method for manufacturing a semiconductor device with silicon oxide film having no cracks and a flat surface. CONSTITUTION:SOG liquid solution is annealed at a low temperature of 700 deg.C or less to obtain SOG film 43a. Since no high-temperature annealing is performed to the SOG film 43a, no cracks are generated at the SOG film 43a. Then, the SOG film 43a and the TEOS film 39 are etched back using dry etching. The TEOS film 39 and the SOG film 43a have the same etching speed in the case of dry etching so that they are etched back while maintaining flatness of the surface 33a. Then, the SOG film 43a is completely eliminated by the etchback.

Title: Set temperature correcting method
Inventor: YAMAMOTO MASAYUKI
IPC: G05D23/19
Filed: 1989-11-02
Abstract: PURPOSE:To attain a set temperature even if an indoor temperature is varied abnormally by adding an absolute value obtained by multiplying a difference between this time measured indoor temperature and the set temperature by a second weight coefficient to an absolute value obtained by multiplying a difference between this time measured indoor temperature and previous time measured indoor temperature, and giving it as a correction value to a temperature adjusting equipment. CONSTITUTION:By a deciding means 3 in a temperature indicating part 1, a difference between previous time measured indoor temperature and this time measured indoor temperature is derived, and whether it is in the direction for approaching a set temperature or in the direction for going away therefrom, or roughly constant is decided. In the case of the direction for going away, an absolute value obtained by multiplying a difference between this time measured indoor temperature and the set temperature by a second weight coefficient is added to an absolute value obtained by multiplying a difference between the this time measured indoor temperature and a previous time measured indoor temperature by a first weight coefficient and it is set as a correction value by a correcting means 4. Subsequently, this correction value is subtracted from the set temperature in the case of cooling, and added to the set temperature in the case of heating, and a correction set temperature in place of the set temperature is given to a temperature adjusting equipment 2 until an indoor temperature becomes the set temperature. In such a way, even if the temperature is varied abnormally, it can be adjusted to the original set temperature.

Abstract: PURPOSE:To stabilize a voltage at a capacitor on a d.c. current side, by constituting a device in such way that an output current detector including the d.c. component of a voltage type inverter is provided in a current feedback system, and the control of an output current is performed by the detected value of the detector. CONSTITUTION:A current detector 7A detects the currents of (a) phase and (b) phase of the voltage type inverter 4 with 'Hall element' current transformers Ha and Hc. The detected outputs of the current transformers Ha and Hc are taken out by a two phase-three phase converter 8 as the currents ia-ic of phases (a)-(c), and are used as the detecting current of a current feedback control system. In the above constitution, d.c. current components are superimposed on the detecting signals of the current transformers Ha and Hc in addition to a.c. current components, and the d.c. current component is also supplied to the current feedback control system. In such way, correction of zero d.c. current is applied on the output current of the inverter 4, and the unbalancing property of the voltage at the capacitor on the d.c. side is eliminated. Also, deviated magnetism in a reactor 3, or an inverter output transformer is prevented from being generated.
