Title: Connecting joint for carburetor in internal-combustion engine
Inventor: NONOGAKI YOSHIAKI
IPC: F02M19/00
Filed: 1982-10-08
Abstract: PURPOSE:To secure a heat shield effect for a carburetor without using a special heat shield member in particular, by composing a connecting joint connecting a suction port with the carburetor of an internal-combustion engine in a way of installing a core member made of heat resistant synthetic resin solidly in a rubber-made body as one body. CONSTITUTION:A connecting joint 9 connects one end opening part 13 of a heat resistant rubber-made body 11 installed in a suction passage 12 inside to a carburetor, while a flange part 14 installed in the other end is connected to a suction port leading to a combustion chamber of an internal-combustion engine and is thus set up. Then, inside a peripheral wall 15 of the said body 11, situated at the suction port side, a heat resistant, synthetic resin-made core member 16 is solidly embedded. With this, heat from the internal-combustion engine is made hard to be transmitted to the core member 16, a method with which a temperature rise in the connecting joint 9 itself is prevented. Accordingly, a heat shield effect for the carburetor can be amply secured instead of using a special heat shield member in particular and a reduction in the number of parts items can be brought to fruition.

Title: Semiconductor memory device
Inventor: TATSUKE KOICHI
IPC: G11C11/409
Filed: 1989-07-10
Abstract: PURPOSE:To attain accurate data read independently of the length of the period by preparing two pullup elements or pull-down elements for one readout line, operating one element for precharge period and operating the other when the readout period is long. CONSTITUTION:When the readout period is long, for example, when the readout period is equal to the natural discharge period of a readout line RL or over, a changeover switch SW connects to the position (b) and P-channel transistor (TR) 10 is turned on. Thus, even if at reading period, the readout RL is charged through a TR 10, and the natural discharge of the readout line RL is supplemented. Moreover, when the readout period is short, for example, when the period is sufficiently shorter than the natural discharge period of the readout line RL, the changeover switch SW is connected to the position (a) and the TR 10 is turned off. Thus, the readout line RL is not charged through the TR 10. Thus, the readout speed is quickened and undesired power consumption is avoided.
