Title: Detecting device for air-fuel ratio
Inventor: HATSUTORI TADASHI
IPC: F02D41/14
Filed: 1979-09-14
Abstract: PURPOSE: To improve the precision of detection of the air-fuel ratio by constituting the device so that the equivalent resistance of a transistor connected to an air-fuel- ratio sensor become small in accordance with the lowering of the resistance value of the sensor by the ratio of temperature.  
     CONSTITUTION: As the temperature of exhaust gas rises, the voltage VA at a point A falls generally and the intermediate voltage VC between peak values at lean and rich times falls below the set voltage VB at a point B, and thus the voltage VC at a point C turns to be used as the bias control of a transistor 102 and the comparison voltage of a comparator 130 in place of the voltage VB at low-temperature time. A comparison circuit 35 performs comparison of the output of a buffer amplifier 103 which is equal to the A-point voltage at the point where an air-fuel-ratio sensor 20 is connected with the transistor 102, with the voltage at a point D, and outputs an air-fuel-ratio detection signal to a point E. Thus, by reducing the equivalent resistance of the transistor 102 in accordance with the lowering of the resistance value of the air-fuel-ratio sensor 20 due to the rise of temperature, the precision of detection  of the air-fuel ratio is improved.

Title: Elevator door control device
Inventor: MORIYAMA KYOICHI
IPC: B66B13/14
Filed: 1993-05-20
Abstract: PURPOSE:To make door opening and closing operation comfortable by calculating the optimal speed reduction position from a bouncing-back quantity of a landing door and a value of slow-moving time of a cage door in a microcomputer, and feeding back these to door speed control. CONSTITUTION:Time until closing of a door is finished after a switch set in an optional position from the closing end is turned on, is measured as slow-moving time. A moving distance in the opening direction up to the closing end from a position detecting device to move by interlocking with a landing door, is measured as a bouncing-back quantity of the landing door. These two measured values are inputted to a microcomputer, and the optimal speed reduction position is calculated in the microcomputer. At this time, slow-moving time is compared with a reference value, and when it is not less than the reference value, a speed reduction correction value is reduced, and a speed reduction position is moved in the closing direction. In this comparison, when it is not more than the reference value, the bouncing-back quantity is compared with a reference value, when it is not less than the reference value, the speed reduction correction value is reduced, and the speed reduction position is moved in the opening end direction. When it is not more than the reference value, the speed reduction correction value is increased, and the speed reduction position is moved inversely in the closing end direction.

Title: Preparation of epsilon-caprolactone
Inventor: NAKANO KAZUHIKO
IPC: C07D313/04
Filed: 1980-08-28
Abstract: PURPOSE: To obtain ε-caprolactone useful as a raw material of polymer, etc., in high yield, by separating and puritying the reaction mixture obtained by oxidizing cyclohexanone with an organic peracid using a specific distillation method, thereby preventing the polymerization loss during the oxidation and distillation steps.  
     CONSTITUTION: Cyclohexanone is oxidized with an organic peracid (e.g. peracetic acid, perpropionic acid, etc.), and low-boiling components (acetic acid, ethyl acetate, unreacted cyclohexanone, and peracetic acid) are distilled out from the reaction mixture. After the treatment, the reaction mixture is again distilled with an apparatus furnished with a one-pass thin-film evaporator to obtain the objective compound. For example, the reaction mixture is fed to a column 1 through the pipe 2 to distill off the low-boiling components, and the bottom residue is supplied to the distillation column 4 for removing high-boiling components and furnished with a single-pass thin-film evaporator 5. The by-product (e.g. polycaprolactone and adipic acid) is removed from the bottom of the evaporator 6 and the objective product is obtained from the top 7 of the column. The polymerization loss can be remarkably reduced by the combination of the proper selection of the reaction mixture based on the organic peracid process and the prevention of contact of the high- boiling components with the objective product utilizing the single-pass process.

Title: Communication controller
Inventor: ANNE SHIYABANETSUTO
IPC: H04L29/06
Filed: 1992-05-12
Abstract: PURPOSE: To enhance the utility of a communication system by switching a virtual channel linked to an SNA session to a backup session defined in a corresponding substitute session table upon the detection of occurrence of failure in the SNA session. CONSTITUTION: Many data terminal equipments 110 are communicated with each other through virtual channels in SNA, X25 networks 112, 109. The communication is controlled by host computers 100, 101 that execute an application program(AP) and communication controllers 107, 108. Each SNA session preset between the AP and the communication controller stores a substitute session table T that defines a priority list of substitute backup sessions. Once the failure in an SNA session has been detected, a virtual channel linked thereto is switched to the backup session in the table T. Thus, end user re-connection is quickly made available and the utility of the communication system is enhanced.
