Title: Controller for charging generator for vehicle
Inventor: TAKAHASHI NAOYUKI
IPC: H02J7/16
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of battery voltage drop to the same level as a generator which generates large power, by adjusting the amount of increase in the control current of a power switch for field current control immediately after electric load application and before actuation of a deenergizing means, based on the state of power generation by a generator. SOLUTION: Generated current to be increased before start of deenergization control at the time of load application is made almost constant regardless of the generated current capacitance of a generator. In a generator different in generated current capacitance, the results of measurement of the amount of increase in field current required to increase the generated current by 10 A immediately after load application and the field current before load application are indicated. In regions with less generated current, the field current and the output current are almost proportional to each other. In regions with larger generated current, the output is not increased even by increasing the field current because the generated current is in proximity to saturation point.  For the reason, the generated current can be made almost constant regardless of the state of the generated current by setting the amount of increase in field current to be increased immediately after load application and before start of deenergization control.

Title: Saving mechanism for magnetic head
Inventor: NEGISHI KENJI
IPC: G11B21/12
Filed: 1987-02-10
Abstract: PURPOSE:To prevent a drop-out by automatically withdrawing a magnetic head in a direction of nearly orthogonally crossing from the rotary plane of a magnetic sheet in interlocking the movement of a head carriage to the area except a magnetic recording and reproducing area. CONSTITUTION:When the head carriage 100 is made to be moved so as to position the magnetic head 102 to the inside or outside of specified magnetic recording area of a magnetic sheet, the sliding part 106A of the head carriage 100 abuts on the large diameter part 120B of a guide axis 120 from the small diameter part 120A of it. As a result, the head carriage 100 turns counterclockwise centering the guide axis 110 on the figure, the magnetic head 102 separates from the magnetic sheet with the turning of the head carriage 100. Since the magnetic head 102 is withdrawing in a radius direction of the magnetic sheet, the dropout in the recording and reproducing area of the magnetic sheet can be prevented.

Title: Vehicle separating device
Inventor: OKABE HIROSHI
IPC: H03K17/78
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To more surely detect the existence of various vehicles, the number of vehicles, etc., by inputting a detection output showing a shielding state as a trigger pulse within a cycle that corresponds to one scan of light beams and outputting a signal that has pulse width that is more than one scan cycle in response to the pulse. SOLUTION: A detection output stabilization circuit 50 discriminates whether signals that are below a threshold level which shows a shielding state within the time width of a window exist equally to or more than a fixed point number or not. An off delay timer circuit 52 detects a cycle when a scan driving part 32 makes one scan of light beams according to an instruction from a control circuit 40, activates an internal timer in accordance with an pulse input with the rise edge of a signal as a trigger pulse and outputs a high level signal that has pulses that are over one scan cycle when a high level signal that shows a shielding state is inputted in each scan cycle. Then, detection outputs that show the existence of a vehicle are continuously acquired even without providing a conventional SOS circuit.

Title: Semiconductor logical circuit
Inventor: NOKUBO JIYOUJI
IPC: H03K19/00
Filed: 1983-02-25
Abstract: PURPOSE:To reduce number of elements constituting a constant current and also to increase a power supply voltage width by feeding back a signal of one emitter to a base in a reverse operation multi-emitter transistor (TR) and operating remaining emitter terminals as constant current sources. CONSTITUTION:In a constant current control section 22, an ICO flows from a reference voltage VR via a resistor R1 and an IC1 is stabilized by feeding back a voltage across the R1 to a base of a Q1 via an emitter follower Q2. That is, when a reverse current amplification factor beta1 of the Q1 is decreased, since the relation of IBXbeta1=ICO+IC1approx.=ICOX2 exists, the ICO, IC1 are decreased. The base voltage of the Q2 is increased in this case, because a value of R1XICO becomes smaller. Thus, since the base voltage of the Q1 is increased via the emitter follower Q2, the IB is increased and feedback is applied so as to flow prescribed currents ICO, IC1. Further, the level of the emitter E1 of the Q1 is decreased up to a level higher by 0.3V-0.4V than a limit voltage VEE by which the Q1 keeps the constant current property. As a result, the permissible width of the power supply voltage being larger nearly by 0.8V than a conventional example is obtained.

Title: Excitation of ultrasonic vibrator array
Inventor: NISHI KENICHI
IPC: G01S7/523
Filed: 1983-02-25
Abstract: PURPOSE:To miniaturize equipment in a simplified configuration by arranging one binary/decimal counter, one decoder and a presetting means to excite or control seventeen vibrators according to an object to be inspected. CONSTITUTION:When a clock pulse 7 is inputted into a binary/decimal counter 6 connected to a decoder 8, the counter starts to count and an output of 1, namely, an pulse output is generated sequentially at output terminals D1-D9 of the decoder 8. The terminals are connected to vibrators as follows: D1 to A9, D2 to A8 and A10, D3 to A7 and A11 and likewise sequentially. Then, the vibrators are excited as follows: A9, A8 and A10, A7 and A11 and likewise sequentially. The final D9 excites A1-A17 positioned on the outermost side of A1-A17. When the flaw detection range varies with the size of the material being inspected, the vibrators from A1 to A17 can be excited partially centered on the vibrator A9 by changing the preset value. For example, to excite the vibrators only from A3 to A15, the preset value is determined as '7' and the counter 6 returns to '0' after counting '1'-'7'. Thus, the vibrators A3-A15 alone are excited.

Title: Television signal processing unit
Inventor: AIDA TORU
IPC: H04N7/015
Filed: 1995-02-20
Abstract: PURPOSE: To prevent production of disturbance noise caused by an identification control signal in a video signal onto a conventional system television receiver by starting the processing from a video signal of a prescribed horizontal line in counted horizontal lines. CONSTITUTION: A synchronizing signal separator section 1 gives a signal Sh resulting from separating a horizontal synchronizing signal Sh and a vertical synchronizing signal Sv from a video signal Vi to a counter 2. The counter 2 counts number of horizontal lines based on the signal Sh and gives a digital count to a video signal processing section 3. In the 2nd generation high definition television system, a video signal, a reinforcement signal and an identification control signal are transmitted. The identification control signal is inserted to a horizontal line of 22H, 285H of a video signal start line of the existing system. The processing section 3 is designed to start processing from 23rd or 286th horizontal line.  Thus, the horizontal lines 22nd and 285th with the identification control signal inserted to them are cut off and the signal is not in existence in an output Vo and then production of disturbance is prevented.

Abstract: PURPOSE:To surely adjust plate thickness with a simple operation and to reduce the adjusting time by setting a roller holder to support a pressure roller for a forming unit so that the roller holder can rotate in the direction of plate thickness centering a supporting pin. CONSTITUTION:The adjustment of plate thickness is carried out by changing a plate thickness adjusting liner 24 of the roller holder 17 supporting the pressure roller 14 with a prescribed liner corresponding to the plate thickness of material. This change is performed by loosing a screw 25, removing the plate thickness liner 24, inserting a new plate thickness adjusting liner 24, tightening and fixing the screw 25. The angle of rotation centering the supporting pin 23 of the roller holder 17 is regulated by this change of the plate thickness adjusting liner 24 and the pressure roller 14 is displaced in the direction of a bisector of a corner part to make a clearance corresponding to a prescribed plate thickness. As a result, the plate thickness adjusting operation is simplified and the adjusting time is reduced.
