Title: Preparation of cycloalkanol
IPC: C07C29/09
Filed: 1992-12-22
Abstract: PURPOSE: To obtain cycloalkanols in a high selectivity while inhibiting by- products and waste water by hydrolysis of cycloalkyl 1-4C fatty acid esters.  
     CONSTITUTION: Cycloalkyl 1-4C fatty acid esters and water are reacted with each other at a temperature of 30-250°C to obtain a reaction mixture comprising cycloalkyl 1-4C fatty acid esters, cycloalkanol, 1-4C fatty acid and water. Then, the mixture is separated at a temperature of 0-200°C into the upper phase comprising cycloalkanol and cycloalkyl 1-4C fatty acid esters, and the bottom phase comprising water and 1-4C fatty acid. The cycloalkanol obtained from the upper phase is separated by distillation, and unconverted cycloalkyl 1-4C fatty acid esters are recycled to the first process. Cycloalkanol and fatty acids are obtd. in a high selectivity, and cycloalkene is hardly formed. Acid is reproduced easily and the amount of waste water under specific demand can be minimized.

Title: Battery protecting circuit and charger/discharger provided with this circuit
Inventor: MATSUURA KAZUHITO
IPC: H02J7/00
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To eliminate wasteful power consumption by an overcharge detecting circuit after the detection of the overdischarge in a battery protective circuit and charger/discharger provided with this circuit and to provided a low-power consumption battery protective circuit and charger/discharger. SOLUTION: An overcharge detecting circuit 14, constituting a part of a protective circuit, contains an inside power supply control means 16. Transistors Q1 to Q3 constitutes a current mirror. A comparator COMP outputs overcharge detecting signals. The inside power supply control means 16 usually has low electric potential at a terminal VS, causing a current IS to flow and thereby actuating a transistor Q4 and an overcurrent detecting circuit. If an overdischarge is detected, charging and discharging paths are disconnected, which causes the rise in the electric potential of the terminal VS and the breaking of the transistor Q6 and transistor Q4. Consequently, the transistor Q1 to Q3 are turned off, which results in a state that no current is consumed by the overcharge detecting circuit.

Title: Carriage and recorder having the same
Inventor: ISONO MASAHIRO
IPC: B41J19/20
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a carriage capable of adjusting a parallelism between a recording face and a head face and a paper gap without adjusting a support position of a guide shaft and to adjust a parallelism between a dot forming element arrangement and a conveying direction. SOLUTION: A recording head 2 is displaced in a direction perpendicular to the recording face with respect to the carriage 1 by the rotation of first bearing members 15, 16 and the recording head 2 is rotated with respect to the carriage 1 centering around a support shaft 10 by the rotation of a γ angle adjusting lever 12. As a result, the parallelism between the recording face and head face is adjusted. The position of the support shaft 10 supporting the recording head 2 is displaced in the conveying direction of a recording medium with respect to the carriage 1 by the rotation of a rotating member 14 and then the parallelism between the dot forming element arrangement and conveying direction is adjusted.  When the support shaft 10 is rotated, the recording head 2 is vertically moved with respect to the carriage 1 by virtue of the eccentric structure of the support shaft 10 so that the paper gap can be adjusted.

Title: Method for feeding air to air spring of rolling stock
Inventor: ISHIKAWA RYUTARO
IPC: B61F5/10
Filed: 1989-12-29
Abstract: PURPOSE:To prevent a reduction in a rolling characteristic of three-point supporting system and improve riding comfortableness by providing such a constitution as connecting the auxiliary air chambers of left and right air springs to each other with a pair of bulkheads having small diameter throttles between, and feeding and discharging air from a height adjusting valve through the small diameter throttles. CONSTITUTION:Throttles 13 of air springs 1, 2 are formed with large diameters, compared with the throttles 10 of an auxiliary air chamber 8. Therefore, when vertical vibration is added, the right and left air springs 1, 2 are the same as in their independent states and damped by the throttles 13 of the air springs. When a rolling stock body is clockwise or counter-clockwise oscillated in rolling vibration, the flow amount of the air through bulkheads 9-1, 9-2 is small because the throttles 10 of the auxiliary air chamber 8 have small diameters. Thus, the right and left air springs are hardly communicated with each other at the time of vibration, and work independently. Consequently, the throttles 10 have the effect of communication even if their diameters are small, and the internal pressures of the right and left air springs are equalized by the lapse of a long time.

Abstract: PURPOSE:To prevent erroneous work by selecting recorded systems in a processing system using a group of processing systems in a series of processing steps and in a processing system using a selected processing system while recording for every object to be processed or a group of objects to be processed thereby specifying use or work conditions of same processing system correctly. CONSTITUTION:A set work and a reference work are set at first in basic fabrication information. Since work A1 is defined as a set work, a selected system and the like are taken in the work achievement of each lot and held therein when the work A1 is carried out. Since work A3 is defined as a reference work, work is guided when the work A3 is carried out upon finish of the work A1 such that a set work is searched based on the basic fabrication information and the system used in the work A1 is used again while taking acount of work achievement thereof. This method allows correct specification of use or work conditions of same system for a series of steps and prevents erroneous work thus fabricating products having good characteristics while suppressing fluctuation in performance.

Abstract: PROBLEM TO BE SOLVED: To accurately detect the positional deviation of a work by a method wherein a prescribed number of light transmitting holes are bored in the play part of a counterbore provided in a holder at a regular interval in a circumferential direction. SOLUTION: N light transmitting holes are bored in the play part of a counter bore 3a provided to a positional deviation detecting holder 3, light rays emitted from a heater and passing through the holes are detected through a light intensity detector 8, and a pulse pattern of light intensity is measured with a computing element 9 and processed through the program. Thereafter, it is judged from the pulse pattern that a wafer 2 is rightly mounted on the positional deviation detecting holder 3. When light rays passing through the two or more light transmitting holes are less than 50%, it is judged that the wafer 2 gets out of the counterbores 3a. In result, it is accurately judged whether it is out of trouble that the wafer 2 is displaced only inside the counterbores 3a on the holder 3 or it is in trouble that the wafer 2 gets out of position overriding the counterbores 3a.

Title: Transmission method and device
Inventor: SATO RYUJI
IPC: H04Q3/00
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent the disuse of a unit signal even though the capacity of a memory placed at a transfer destination is not large so as to withstand the burst-like transfer of the unit signal by allocating accurately, evenly and separately the effective band of the unit signal within a transmission line band. SOLUTION: An adder 21 adds together an effective cell band M and the output of a selector 24, and a subtracter 22 subtracts a transmission line band N from the output m1 of the adder 21. A comparator 23 compares the band N with the output m1 and outputs a high level (cell output enabling signal) when m1>=N is satisfied. A selector 24 alternatively selects and outputs the output of the adder 21 or the subtracter 22 to be supplied to an input terminal '0' or '1' in response to the output of the comparator 23 that is supplied to a control terminal. Thus, an accurate number of M cells is secured and the fractions are completely absorbed in N clock periods even though the ATM cells to be read out of a memory part in time series are extracted in any one of continuous N clock periods.
