Title: Negative electrode for lithium secondary battery and manufacture thereof
Inventor: NODA TOMOHIKO
IPC: H01M10/05
Filed: 1992-01-23
Abstract: PURPOSE:To make the distribution of the current constant at the time of charging a battery. CONSTITUTION:In a negative electrode of a lithium secondary battery, a crystal grain of the surface of the lithium has an edge without corner. In the manufacture of the negative electrode, lithium formed into a predetermined shape is discharged preparatively. The preparatory discharge can be performed after assembling the lithium into a lithium secondary battery. When the lithium is discharged preparatively, roundness is given to the edge of a crystal grain of the surface of the lithium to relax the concentration of the current to the edge at the time of charge. Consequently, the generation of dendrite is restricted to obtain the lithium secondary battery having the excellent cycle lifetime.

Title: Method for controlling carriage of printer
Inventor: NISHIZAWA KATSUHIKO
IPC: H02P8/06
Filed: 1987-02-18
Abstract: PURPOSE:To achieve the miniaturization and enhancement of capacity of a printer, by changing over the phase of a stepping motor after a second predetermined time when a motor timing signal imparting the max. rotary torque is generated within a first predetermined time. CONSTITUTION:In acceleration control, a phase is changed over as a rule on the basis of phase change-over timing by the later one among an MTS signal and acceleration data tDn (n=1-12). When a speed order NmPPS (Pulse Per Second) (m=1-3) is applied to slave CPU2 from main CPU1 corresponding to a printing mode, the phase change-over is performed by a phase change-over circuit 50 and, at the same time, a phase change-over cycle setting data table 52 corresponding to NmPPS is referred to allow a timer 53 to run. Thereafter, the next change-over is performed on the basis of the later interruption among the interruption from the timer 53 and the MTS signal interruption from an encoder 51. CPU2 confirms the MTS signal within a TX-time on the way of the output of a timer value tD to detect that the speed of a stepping motor becomes too fast and a time TY timer is allowed to run in place of a tD timer and TY interruption is applied at a position later than tD to further achieve torque reduction.

Filed: 1990-02-15
Abstract: PURPOSE:To increase the processing speed by storing management information to be recorded on an optical disk in the RAM of a device main body and collectively recording it on the optical disk at the time of ejecting the optical disk. CONSTITUTION:Management information to be recorded on an optical disk 1 is stored in a management information storage area 4a of a RAM 4, and identification information to manage recording of the management information to the optical disk is stored corresponding to the identification information storage area 4b. Stored contents of the RAM 4 are held by a backup power source 5 even at the time of power-off. Consequently, the management information stored in the management information storage area 4a is surely recorded on a management information recording area 1a of the optical disk 1 when power is restored and ejection of the disk is instructed from a switching circuit 7. Thus, management information is recorded on the optical disk 1 only one in the period from loading to ejection, and the recording processing speed is increased.

Filed: 1994-03-07
Abstract: PURPOSE:To provide an optical scanning device without causing the fluctuation of a scanning position due to the change of ambient temp., etc., 'the state of use and service conditions, etc., and performing stable optical scanning. CONSTITUTION:A laser beam transmitted from a distributed feedback-type semiconductor laser 10 stably oscillating in a single wavelength and having the small fluctuation of wavelength to ambient temp. is diffracted by a hologram lens 12 for compensating aberrations and a scanning hologram 14. However, since the distributed feedback type semiconductor laser 10 oscillates in two wavelengths before and after a Bragg wavelength determined by the period of a diffraction grating, two diffracted light beams are generated. By making only one diffracted light beam 34 transmit through by means of a selecting slit 16, a photo receptor drum 24 is irradiated with only a laser beam having one wavelength. Consequently, stable optical scanning is performed.

Title: Pattern forming method
Inventor: MATSUDA KOREHITO
IPC: H01L21/302
Filed: 1985-02-25
Abstract: PURPOSE:To improve the pattern forming accuracy by detecting a boundary between a bonding material and a sensitive material, and discriminating the etching end point of the bonding material on the basis of the detection, thereby accurately discriminating the etching end point of a mask material. CONSTITUTION:An etching state is monitored by a mass analyzer 11 connected with a reactive ion etching unit 10. When the etching of a silicone resin 4 is proceeded so that the flat portion of a resist starts exposing, Zn contained in the resist is detected by the analyzer 11 to a mass spectrum M/e=32.5. This state is that the resin 4 is not disposed at the flat portion of the resist but exists only on a recess pattern. Then, when the etching of the resin 4 is continued by the etching time calculated by the etching rate of the resin 4 and 1/2 of the remaining thickness, the resin 4 is accurately etched to the depth of 1/2 of the recess pattern.

IPC: F02M59/44
Filed: 1989-02-15
Abstract: PURPOSE:To get rid of any seizure or binding of a loose fitting part between a tappet pin and a tappet roller by installing such a mechanism as making lubricating oil fed to a lubricating oil passage from a lubricating oil inlet passage flow out of an opening in a forced manner. CONSTITUTION:A tappet consists of a tappet body 4, a tappet pin 2 and a tappet roller 3. When a lubricating oil passage 7 and a lubricating oil inlet passage are interconnected to each other, lubricating oil is merely leaked out of an opening 7a because this opening 7a at a left end of the lubricating oil passage 7 comes into contact with a wall surface 5b of a cylinder 5a of a housing 5. The lubricating oil forcedly passes through a lubricating oil passage 8 and flows into a loose fitting part between the tappet pin 2 and the tappet roller 3 from an opening 8a. Thus, seizure of binding in the loose fitting part is kept back, and durability of a device can be improved.

Abstract: PURPOSE:To improve pump efficiency in such a way that thermal expansion and swelling of a resin member to cover the base member is controlled by the base member of a vane, and the clearance between the vane and the housing is minimized by controlling the thermal expansion and swelling of the vane. CONSTITUTION:A vane 10 has a base member 34 and a resin member 36 to cover this base member 34, and the base member 34 is made of metal with high intensity and rigidity, such as aluminum plate, copper plate, steel plate, or another. And as for the vane 10, since the base member 34 controls thermal expansion and swelling of the resin member 36 which covers it, overall thermal expansion and swelling of the vane 10 are controlled. Thus, it is not necessary to set a large clearance as before in expectation of thermal expansion and swelling of the vane between the vane 10 and the housing 14, this clearance can be made undersized, and efficiency of an air pump can be improved.

Title: Vertical magnetic recording floppy disk
Inventor: UEKI MASAYUKI
IPC: G11B23/033
Filed: 1984-02-27
Abstract: PURPOSE:To prevent the noise produced by the electrostatic discharge generated independently on both sides of a disk, by providing a conduction path which connects electrically the upper and rear sides of the disk. CONSTITUTION:When the static electricity is discharged between both sides of a disk by some reason, an instant current produces noise to the vertical magnetic recording/reproducing signal of a vertical head. This deteriorates the quality of the reproducing signal. In this respect, a center hole 6 of the disk is formed by blanking a long-size sheet in a slightly larger diameter. Then a conductive coating material 12 is applied to the inner side surface of the hole 6 and dried. Then an electrical short circuit is caused between both sides of the disk. A normal inner diameter is decided for the hole 6 after the material 12 is coated. The same purpose can be attained also by applying a conductive coating material 13 to the outer side surface of the disk fringe.
