Title: Prime roofing material
Inventor: TAMEI MASAKATSU
IPC: D06N7/00
Filed: 1994-12-15
Abstract: PURPOSE: To provide a prime roofing material applicable in a simple way in a short time without impairing its waterproofness, with no relevant workers endangered during application, and capable of improving its applicability. CONSTITUTION: This prime roofing material is so designed that the back surface of a base material layer 1 is provided with a repeelable tack layer 2 with a peel strength to a roofing substrate of <=1.0kg/25mm. Owing to the tackiness of the tack layer 2, this roofing material can be fixed onto the substrate, rendering needless to use any tacker. As this roofing material can be fixed through the tack layer 2 simultaneously with laying the roofing material on the substrate, relevant worker(s) can be ensured not to slip down the roofing material along the slope of the substrate even if he (they) get on the roofing material. Besides, because the tack layer 2 has the above-mentioned characteristics, it can be peeled off again after applied onto the substrate, facilitating correction of its applied position.

Title: Idle speed controller for internal combustion engine with variable valve timing mechanism
Inventor: TERAOKA MASAHIKO
IPC: F02D13/02
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent unstable rotation of an internal combustion engine at the time of idling, so as to prevent engine stall by conducting ISC corresponding to the number of failures in variable valve timing mechanisms (VVT) at the time of failure of the VVTs in the internal combustion engine. SOLUTION: The targeted rotational speed (S130) of an ISC and the opening of an ISCV (S135) when one VVT has abnormality in timing advance ('NO' at S110 or 'YES' at S120) are set larger (S140, S145) than those when all VVTs are normal ('NO' at S100 and S120), they are set further larger (S150, S155) when two VVTs have abnormality in timing advance ('YES' at S100 and S110). The number of the abnormal VVTs are reflected in the targeted rotational speed of the ISC and the opening of the ISCV, thus it is possible to prevent idle rotation from becoming unstable regardless of the number of the abnormal VVTs, and prevent engine stall effectively.

IPC: A23F3/06
Filed: 1988-12-14
Abstract: PURPOSE:To perform the processing of tea leaves at a proper drying rate during a water-content controlling step by measuring the actual drying speed of tea leaves at a proper time in a water-content controlling step in the tea-processing and judging whether the actual speed is within the permissible drying speed range of said water-content controlling step. CONSTITUTION:When a water-content controlling step of tea leaves is started, the final water-content and the finishing time preset by an operator are judged to be adequate or not in relation to the proper drying speed of the tea leaves in said water-content controlling step. If the speed is judged to be inadequate, the water-content control is continued at a prescribed drying speed DA to enable the processing of tea leaves constantly within the adequate drying speed range. Accordingly, the charged tea leaves is treated at a drying speed DA shown by the inclination of the line [alpha, B(T0)]-[T2, A(T1)] of Fig.1. When a time- discharge mode is in selected state, the processing is finished at the time T2 and when a water-content discharge mode is in selected state, the water-content controlling step is completed at the water-content A(T1). The continuation of tea processing based on inadequate water-content and finish time can be prevented by this process to enable the preparation of tea having high quality.
