Title: Photoelectric type smoke detector
Inventor: TOKI AKIRA
IPC: G08B17/107
Filed: 1990-03-27
Abstract: PURPOSE:To shorten time required for action checking even when a smoke detector is a storage action type by outputting a fire signal when a smoke detecting output is obtained once at the action checking. CONSTITUTION:When a read switch S is turned on for action checking, the one input of respective AND circuits A1 and A2 becomes a high level. When an oscillation output Lout is generated in this condition, the output of the circuit A1 becomes the high level, resistance R16 is connected parallel to current limited resistance R11 and the light emitting quantity of a light emitting element 1 is increased. Thus, a stray light portion is increased and the pseudo fire occurring condition is made. That is, at this time, a light receiving quantity increased by the stray light portion of a light receiving element 2 is over a fixed level, an output Tout becomes the high level and a fire signal is outputted from a switching circuit 3. Thus, since the fire signal is outputted immediately when the light receiving quantity of the element 2 becomes more than the fixed level once, it does not take much time for action checking even when a sensor is the photoelectric type smoke detector to execute what is called a storage action.

Title: Tape recorder
Inventor: TAKAI ISAMU
IPC: G11B15/093
Filed: 1979-06-20
Abstract: PURPOSE: To ensure the low-cost detection for the termination of the cassette tape both ends of which are fixed to the reel hub, by detecting the current change of the tape running drive motor and then obtaining the tape termination signal.  
     CONSTITUTION: With the sudden increase of current IM of tape running drive motor 1 at the tape termination, the voltage drop of resistance 2 increases. And then the base potential of transistor 3 increases, and accordingly the emitter potential also increases. As a result, the base potential increases for transistors 5 and 6 which form differential amplifier 4. The difference of the base potential between transistors 5 and 6 and caused by the change of motor current IM is turned to the input of amplifier 4. Thus the relation as shown in Fig2 is secured between differential output VO supplied from terminals 4a and 4b each and current IM. Change A of output VO is used for the tape termination detection signal in order to secure the start for the automatic stopping device or the tape termination warning circuit. In such way, the low-cost and effective detection is possible for the tap termination.

Title: Additional fuel feed device for internal-combustion engine
Inventor: TAKAO MITSUNORI
IPC: F02D41/00
Filed: 1984-04-17
Abstract: PURPOSE:To enable provision of excellent acceleration properties, by a method wherein, even if a load change amount exceeds a first set value and additional fuel feed by nonsynchronous injection is executed, when the change amount is below a second set value, the number of synchronous injection times is thinned out. CONSTITUTION:The load amount of an internal combustion engine I is detected by a detecting means II, and an amount of a change produced during a given time is calculated by a change amount calculating means III. When the calculated change amount exceeds a first set value, a given fuel amount is injected by given synchronism of non-synchronism with the aid of an additional fuel feed means IV, and this eliminates defficiency in fuel due to an increase in a load. However, during slow acceleration in which a change amount exceeds a set value and is below a second set value, the number of injection times, executed by the means IV, is thinned by a thinning control means V, and this prevents the occurrence of excess of fuel due to non-synchronous injection during slow acceleration, enables an air-fuel ratio to be always kept at an excellent value, and prevents worsening of emission.
