Title: Magnetic picture recording and reproducing device
Inventor: KOGA YOSHIO
IPC: G11B15/093
Filed: 1988-04-22
Abstract: PURPOSE:To prevent a tape from being damaged by detecting a rotating direction of a capstan and controlling a reel motor in relation to the tape take-up condition. CONSTITUTION:A rotating direction detecting means 80 for outputting a reverse rotation signal during at least a reverting time of the capstan to its forward rotation after detecting the rotating direction of the capstan 12 under rewinding reproducing; is provided to connect the reel motor 6 on the supply side (in this case, take-up function) to the take-up side under said circumstances. In this circuit constitution, at the time of closing and after opening a rewinding reproducing switch 74, the rotating direction detecting means 80 outputs the reverse rotation signal 81 during the reverting time for the capstan 12 to the forward rotation. By this method, even at the time of rewinding reproducing, and even after opening the rewinding reproducing switch 74, the tape can be kept under non-slackening state, thus preventing the tape from being damaged due to deviation from its traveling course.

Title: Semiconductor integrated circuit
Inventor: KUMAGAI SABURO
IPC: H01L21/822
Filed: 1988-04-22
Abstract: PURPOSE:To cut down the guess time of a changing point by a method wherein a discordance detecting signal pin which outputs the discordance detecting signal furnishing data on the non-comparison term between an output data signal and an expected value signal is provided. CONSTITUTION:An output data signal 1 transmitted from a semiconductor integrated circuit 11 is externally outputted by an output data signal outputting pin 8. A delay circuit 5 inputs the output data signal 1 and outputs delay data signal 3 which is the output data signal 1 delayed by specified time. A discordance detecting circuit 6 outputs a discordance detecting signal 4 at low level voltage when the output data signal 1 accords with the voltage level of the delay data signal 3 but outputs another discordance detecting signal 4 at high level voltage when the output data signal 1 discords with the voltage level of the delay data signal 3. The discordance detecting signal 4 is externally outputted from a discordance detecting signal outputting pin 10. When the discordance detecting signal 4 inputted in a comparator 7 at low level voltage, the output data signal 1 is to be compared with an expected value signal 2 but when the discordance detecting signal 4 is reversely at high level voltage, the output data signal 1 is not to be compared with the expected value signal 2. Through these procedures, any erroneous data during the term when the data in a data bus are unstable can be prevented from being read-in.

Title: Combustion chamber for internal combustion engine
Inventor: NAITO TAKESHI
IPC: F02F1/42
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To restrain the fuel spray, which comes from a fuel injection valve, from sticking to a cylinder head wall surface. SOLUTION: In a combustion chamber, a recessed part 5 is formed on a cylinder head wall surface 6 on the ignition plug 2 side in the vicinity of a nozzle of a fuel injection valve 4. Now, an angle formed between the spray central axis and the outer peripheral surface of the spray, when the fuel is injected under the atmospheric pressure outside the combustion chamber of the fuel injection valve 4, is denoted to be θ1. At this time, an angle θ formed by the inclined wall surface of the recessed part 5 and a conical surface, which makes the angle θ1 from the spray central axis of the fuel injection valve 4 after its installation in the combustion chamber, is set at a value greater than the angle θ1.  With this contrivance, since an occurrence of the force drawing the fuel spray toward the cylinder head wall surface 6 is restrained, the combustibility becomes stable, while the quantity of the soot produced can be reduced.
