Title: Controller for diesel engine
Inventor: TERASAKA YOSHITSUNA
IPC: F02D41/12
Filed: 1980-07-29
Abstract: PURPOSE: To avoid a peculiar or unpleasant feeling due to sharp deceleration, by prescribing a limit value for the rate of decrease in the injection of fuel at the time of deceleration to control the degree of the deceleration.  
     CONSTITUTION: An injected quantity calculation circuit 105 calculates an injected quantity on the basis of a revolution speed signal S 2  and an accelerator position signal S 3  to send out an injected quantity signal S 6 . A subtraction circuit 106 sends out a signal S 8  corresponding to the difference between the present injected quantity S 6  and the preceding one S 7 . A limit value setting circuit 109 sends out a limit value signal S 9  corresponding to a gear position signal S 4 . A comparison circuit 107 compares the signals S 8 , S 9 , with each other. When the signal S 8  is equal to or higher  than the signal S 9 , a signal S 12  produced by subtracting the limit value S 9  from the  quantity S 7  which is injected a predetermined time ago is sent out as a fuel injection  control signal OS 4  so that the rate of decrease in the injected quantity is controlled  to be reduced by the prescribed limit value. As a result, the degree of deceleration  is lowered not to give a rider a peculiar or unplesant feeling.

Title: Television equipment
Inventor: YASUDA HIDEFUMI
IPC: H04N7/167
Filed: 1983-06-08
Abstract: PURPOSE:To improve security of control in a CATV system having two systems of cables connecting the center and a terminal converter by inserting a code signal for discriminating transmission line during vertical flyback time of a video signal. CONSTITUTION:For instance, a code signal of ''1'' is given to a channel supplied through a transmission line A, and a code signal of ''0'' is given to a channel supplied through a transmission line B. When channel selection operation, the terminal monitors selected channel by a microcomputer. When it is a channel of transmission line A, ''1'' is raised and if it is a channel of transmission line B, ''0'' is raised. It is judged by a microcomputer whether these code signals coincide with code signals sent from the center. In the case of coincidence, channel selection is made as it is and if they do not coincide, a specified channel is selected.

Title: Control signal processing system for internal combustion engine
Inventor: HONDA TAKAYOSHI
IPC: F02D45/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To accurately determine various kinds of control signals, which are observed in an ionic current, for an internal combustion engine without being affected by a noise component or the like from the outside. SOLUTION: DFT frequency analysis is conducted by a processing part 44 in a DSP 40 of an ECU 20, using an ADD-converted value ADD-converted by an A/D converter 42 after extracting a prescribed frequency component, e.g. a knocking detecting signal, contained in #1-#4 ionic currents flowing between an ignition plug and a gland by an LPF 27, an HPE 28 or the like. Knocking determination is carried out based on a result by the frequency analysis to determine an operation condition of an internal combustion engine. That is, since a feature, for example generation of a noise or superposition of a noise, is observed remarkably in the result of the frequency analysis in the frequency analysis after the prescribed frequency component contained #1-#4 ionic currents is A/D-converted to be digitalized, the operation condition of the internal combustion engine is accurately determined.

IPC: E05B65/02
Filed: 1992-04-22
Abstract: PURPOSE:To prevent a furniture body from being damaged due to collision with a lock member, etc., by controlling a mis-operation, in a door open area, of key bars engaged with the furniture body in connection with the lock member and inserted into a door in an unlock position. CONSTITUTION:When a door is closed completely, the outer side of a turning element 61 is made in contact with a contact surface 82 of a cap 8 and the turning element 61 rotates the cap 8 to an escape position to release a lock member 4. Accordingly the top 42 of the lock member 4 is engaged with the engaging recess 81 of the cap 8. Also the lock member 4 is rotated to rotatably deviate the deviated positions P1 and P2 of the lock member 4. Next, a key bar 5a is raised to protrude its top end from the door and to engage with a downward engaging hole in a body and also to protrude its bottom end from it and to engage with an upward engaging hole. Then the protruded ends of the upper and lower key bars 5a and 5b are pushed in the door by the key operation in reverse direction to enable opening of the door. Consequently the door is opened, and the turning element 61 is released from restriction by the cap 8 and returned from the escape position to a locking position by an energizing force of a spring 62 to insert and lock an inner rotational end to a notched section 43.

Title: Production of potassium sulfate
Inventor: KIURA YOSHINORI
IPC: C01D5/02
Filed: 1981-07-03
Abstract: PURPOSE:In the production of potassium sulfate by a reaction of potassium chloride with sulfuric acid, the neutralization is conducted at a temperature higher than the melting point of acid potassium sulfate contained in the reaction mixture to produce substantially neutral potassium sulfate. CONSTITUTION:When potassium chloride is made to react with sulfuric acid to give a reaction mixture, the present invention is applied in case that neutralization is required, because the amounts of the potassium chloride and sulfuric acid are stoichiometric or proportion of sulfuric acid is a little less. However,  in order to satisfy both of two requirements for obtaining the extremely low  chlorine content and substantial neutrality, the reaction mixture is desired to contain sulfuric acid at an equivalent ratio of 1.05-1.40 to potassium chloride.  The neutralization is effected by adding a neutralizing agent to the reaction  mixture at a temperature higher than the melting point of acid potassium sulfate. At this point, if the temperature is lower than the above melting point,  both of the reaction mixture and the neutralizing agent keeps a state of dried powder or lumps and remain only physically mixed, not giving substantially  neutral salt. On the contrary, when it is higher than the melting point, the  chemical neutralization presumably proceeds smoothly.
