Patent JP-H10229608-A (JP)
Title: Braking device of electric vehicle
Inventor: TAKENAKA YASUHIRO
IPC: B60L7/22
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To assist a braking force by regenerative braking at the time of quick braking. SOLUTION: It is judged from the speed of a braking operation that a quick braking is intended (S102). Further, it is judged whether or not the applied braking force is less than the maximum braking force of the capability of a wheel (S104). It is decided from those conditions whether or not an assistant braking force at the time of quick braking is necessary. If it is needed, in addition to a friction braking, corresponding to a braking operation quantity, regenerative braking is performed (S106).

Title: Bar code detecting circuit
Inventor: IIMURA HIROSHI
IPC: G06K7/00
Filed: 1990-02-08
Abstract: PURPOSE:To reduce the burden to a CPU and to increase the processing speed by automatically executing the processing up to detection of the relative ratio of a fundamental element width which is not related to the classification and the use of a bar code. CONSTITUTION:An element boundary detector 1 generates a control pulse by the rise and the fall of an inputted sense signal, and a counter 2 stores the coefficient value of the reference clock from a clock generator 3 in an element width register 4 consisting of two stages of shift registerts by the control pulse. The relative ratio in each stage of the element width register 4 is calculated by a relative ratio computing element 5, and the result is successively stored in a relative ratio register 6 and is sent to the CPU through an interface circuit at the time of the end of scanning and is converted to a character code. Thus, the burden to the CPU is reduced and the processing speed is increased.

Abstract: PURPOSE:To further reduce carbon content and to obtain an extremely low carbon steel by forcibly stirring molten steel when the measured value or the assumed value of the carbon content in the molten steel during degassing treatment reaches the specific content. CONSTITUTION:Into the molten steel 4 covered with slag 5 charged in a ladle 2, submerged tubes 12, 14 at the lower part of the degassing vessel 10 are submerged. Successively, the inner part of the degassing vessel 10 is evacuated a gas exhaust device 19 connected to a gas exhaust hole 18 and the molten steel 4 is sucked up into this to the prescribed level.

Then, CO concn. in the exhaust gas is detected with an exhaust gas analyzer 20 arranged at the gas exhaust hole 18. The carbon content in the molten steel 4 is assumed with a computer 21 from this detected value, and when the assumed value lowers to <=20ppm, by controlling an inert gas supply device 22, gas blowing is changed over and the circulating passage of the molten steel 4 is inverted. By this method, forcible stirring is given to the molten steel 4 to promote the decarbonization and the extremely low carbon steel having <= about 10ppm can be obtd.

Title: Winding and rewinding device for camera
Inventor: KOU HIDEO
IPC: G03B17/00
Filed: 1983-02-28
Abstract: PURPOSE:To prevent the damage of a film and to start rewinding the film exactly by transmitting the revolution of a motor only to the spool to wind the film and starting the reverse run of the motor by the output of a timer circuit which is set at the time longer than the time when film is wound for one frame. CONSTITUTION:A timer circuit 76a is set longer than the time required for winding a film for one frame. A motor 1 is run forward by the winding mode for the film, and the film is automatically and securely wound on a spool 33 by the effect of the spool 33. The spool 33 and a sprocket 55 stop moving upon completion of the full winding of the film. The winding of the film is not completed even if the preset timer time elapses and therefore the motor 1 is run reversely by the operation of a control circuit 76, by which the film is automatically rewound.

Abstract: PURPOSE:To prevent dirts from remaining on semiconductor wafers in the washing process, by a method wherein pins which enable the rocking of a wafer boat and which can be moved up and down with the rocking of the wafer boat are provided, and wafers are rotated when these pins rise. CONSTITUTION:A wafer boat containing many semiconductor wafers 5,... is immersed in a washing liquid. Next, the wafer boat is rocked laterally by applying some force. Further, when a moving plate 8 comes into contact with the bottom of the washing container by the one-side inclination of a support base 6, pins 9,... rise and come into contact with the periphery of the semiconductor wafers 5,.... The wafers 5,... rotate by giving them an upward force. Since the use of a wafer boat enables said rotation of wafers 5,... every time the support base 6 inclines in one direction, the parts of contact of the wafers 5,... with the guide 3 of the wafer boat and supports 4,... are not fixed during the washing process. As a result, any part of the semiconductor wafer 5 can be sufficiently washed.

Title: Antipruritic for external use
Inventor: YARITA TAKAKO
IPC: A61K36/48
Filed: 1984-02-20
Abstract: PURPOSE:To provide the titled remedy effective to the swelling, itchiness, ulcer, etc. caused by the sting of mosquito, and preservable for a long period, by leaching or decocting the leaf of arrowroot with water, and using the obtained extract as a component. CONSTITUTION:The leaves of arrowroot are collected together with the vine, and washed with water. The leaves are dried spontaneously or forcibly, and the vine is removed after drying. The dried arrowroot leaves are immersed and reconstituted in water or not water for 24hr with occasional agitation to effect the extraction of the active component. The obtained extract is used as the antipruritic for external use. Since the active drug component of arrowroot leaf is soluble extremely easily in water, it can be sufficiently extracted without squeezing or pressing. The obtained aqueous solution can be used asd it is as a liquid drug, however, when boiled, it is converted gradually to viscous ointment. The boiling is effective to sterilization and the increase in the concentration. The active component decomposes if the heating temperature is unnecessarily high. The agent is effective also to the itchiness caused by the contact allergy with cloth, yam allergy, etc.

Title: Cleaning device for screen printing machine
Inventor: HACHIMAN SATOSHI
IPC: B41F15/12
Filed: 1992-02-19
Abstract: PURPOSE:To obtain a cleaning device for a screen printing machine which can always conduct sharp printing without an ink residue on a mask and a contamination on a substrate. CONSTITUTION:A cleaner is slid with a cloth 6 brought into pressure contact with a mask 2. A means for forming an air flow to the cloth 6 through openings of the contact part of the mask 2 is provided. As a result, an air flow to the cloth is formed through the openings of the mask 2. An ink residue in the openings of the mask 2 is peeled off the inner walls of the openings by the air flow and forced outside, thus being easily wiped off with the cloth 6. In addition, since the air flow inhibits the dissociation of fibers of the cloth 6, the fibers of the cloth 6 are not transferred to a substrate. Therefore, a large cleaning effect can be obtained, an ink residue does not remain on the mask 2, the substrate is not contaminated, and sharp printing can be always conducted.
