Title: Operation storage device
Inventor: TANAKA TAKASHI
IPC: G06F3/02
Filed: 1990-11-30
Abstract: PURPOSE:To save the time of repeated operation and to improve operation without being influenced by the kinds of software by storing operation data of an input device in terms of hardware, reading it out if necessary and reusing it. CONSTITUTION:When operation data is inputted from the input device 1a, storage starting request is given from outside at the time of needing the preservation of the operation data. A preservation judgement means 12 gives a preservation data name inputted from outside to operation data based on the storage starting request and preserves operation data in a preservation part 13. When the preservation data name related to the operation is given at the time of repeated operation, an operation data repetition means 14 reads out operation data corresponding to the preservation data name from the operation data preservation part 13 and operates in place of the operation. Thus, repeated operation time is saved and operation is improved without being influenced by the kinds of software.

Title: Outside mirror for automobile
Inventor: NEMOTO TOSHIHIRO
IPC: B22D17/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide an outside mirror for an automobile capable of simplifying the base shape and reducing the weight. SOLUTION: The base 4 of a door mirror 1 is formed from magnesium material instead of aluminum die-cast. Because the magnesium material excels in the vibratory isolating characteristics originating from its nature, there is no need to resort to a structural vibration controlling measure (ribs), which allows simplifying the shape of the base and facilitating the manufacture. Because the magnesium material accepts an injection molding process, it is possible to perform mass-production. Also because the magnesium material has a smaller specific gravity than aluminum die-cast, a lightweight construction can be established.

Title: Stress level determining device
Inventor: YANAI TATSUMI
IPC: A61B5/0245
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of determining the stress level of a tested person by reducing an influence upon measurement exerted by measurement environment such as a measuring device or a measuring person and disturbance such as noise. SOLUTION: While a task of clicking a target on a screen through mouse operation and a rest for break are alternately presented by a target presenting device 1, a pulsation signal of a tested person is measured by a heartbeat corresponding data picking device 3. The pulsation interval dispersion value and the average heart rate are calculated by a sympathetic-parasympathetic nerve activity calculating circuit 4 to find the distribution area on the two-dimensional plane at the time of a task and a rest. The area is reduced to a distribution centralized area with a high distribution density by a determination circuit 5 to decrease an influence of disturbance such as noise, and secondly, the presentation time of a target is reduced by a presentation control circuit 2 to raise the difficulty of the task.  Thus, a healthy person nervous about the measurement environment such as a measuring device or a measuring person and a person who requires medical care having a high stress level are discriminated, and then the stress level of the tested person is determined from the distribution centralized area at the time of a task and a rest.

Inventor: MAKITA ATSUSHI
IPC: C07B61/00
Filed: 1991-12-02
Abstract: PURPOSE:To produce a large cyclic ketone in high yield without requiring special purification by subjecting a diesterification product of straight-chain alkanoic diacid to acyloin condensation to carry out intramolecular cyclization and then reducing the resultant acyloin condensation product using a specified sulfuric acid having low corrosion resistance. CONSTITUTION:A diesterification product of a straight-chain alkanoic diacid of formula I [(n) is 12-18] is subjected to intramolecular cyclization by an acyloin condensation reaction to afford an acyloin condensation reaction product of formula II. Then the product is reduced using a >=14N and <26N sulfuric acid and zinc powder to provide the objective large cyclic ketone of formula III. Reduction yield is improved and a large cyclic ketone having low degree of pigmentation is obtained in remarkably enhanced production efficiency due to the use of >=14N and <26N sulfuric acid. The resultant large cyclic ketone exhibits musk-like smell and is useful as a perfume or a compounding substrate thereof.

Title: Device for connection of double-faced printed-circuit board
Inventor: ISHIYAMA TAKESHI
IPC: H05K3/40
Filed: 1989-12-27
Abstract: PURPOSE:To obtain a device for connecting a double-faced printed board which has high bendable and soldering reliability, easy management of operating steps and easy automation by covering a soft core wire having conductivity with solder, and further bending it to form a U-shaped connecting tool. CONSTITUTION:When front and rear conductive patterns 8, 9 are electrically connected with a connecting tool 6, the tool 6 is bent in a U shape, and its both ends are inserted into through holes 7a, 7b. Then, the ends protruding from the holes 7a, 7b of the tool 6 are bent inside, and temporarily clamped on a board. Since the part of the tool 6 is always disposed on the patterns 8, 9, if other mounting component is, for example, reflow-soldered, the tool 6 is heated. If it arrives at a temperature higher than the melting point of the solder, solder 6b coating the wire 6a is fluidized, and fusion-adhered to the wire 6a and the patterns 8, 9 by capillary tube phenomenon by obtaining an aiding force of flux, etc. Even when other mounting component is dip- soldered, the solder 6b is melted with conduction heat while the dipped surface is immersed in a dip tank. Accordingly the wire 6a can be soldered to the patterns 8, 9.

Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To obtain a predetermined resolution and record images of many gradations in a short recording time without complicating a control circuit or wasting a replacement ink by setting a segmenting means for segmenting ink drops discharged from nozzles. SOLUTION: An internal volume of an ink pressurization chamber 4 is changed by driving an ink-pressurizing element 5 or ink in the ink pressurization chamber 4 is pressurized by membrane ebullition, whereby ink drops are discharged from a nozzle 8 via a nozzle communication path 7. At this time, high frequency vibration is applied to a nozzle part 9 by an oscillating member 10 before the ink drops are discharged from the nozzle 8. As a result, the ink drops discharged from the nozzle 8 are segmented and discharged as segmented ink drops 11. In this case, although the segmented ink drops 11 have an equal amount to the original ink drops, a size is reduced and a size of dots formed when the ink drops hit on a recording medium becomes small.
