Abstract: PURPOSE: To efficiently carry out a whole embroidery work containing repair sewings after reversing a moving frame (a rotating frame) in a short time in occurrence of thread breaking, etc. CONSTITUTION: In this automatic embroidery machine, a twin back control is carried out by reversing solely a frame moving motor and a frame rotating motor for 2 stitches from the stopped position toward a reverse direction against a forming direction of an embroidery pattern based on a reverse moving command at the step 11, when an embroidery work is once stopped at the step 10 caused by the occurrence of a thread braking and the moving frame and the rotating frame are reversely moved toward a needle center position for two stitches.  The twin back control is automatically stopped when a twin back number λ is 'λ=0' and a judgment is made 'yes' at the step 13 and a message is displayed as 'stopping caused by thread braking', etc., while a thread treatment is carried out at the step 16 and a successive embroidery work is continued by carrying out repairing stitches from the stopping point at the step 18 after restarting at the step 17.

Title: Laminated board for printed wiring board
Inventor: NAWA KAZUNARI
IPC: B29B11/16
Filed: 1993-03-08
Abstract: PURPOSE:To lessen a rigid board of a printed wiring board in dielectric constant, wherein prepregs are laminated and formed into a rigid board. CONSTITUTION:Above 10% by volume of micro voids below 10mum in diameter are contained in a board. The micro void-containing rigid board is formed through such a manner that prepregs wherein condensation-type thermosetting resin is used as matrix resin are laminated and formed through a hot press process carried out, at least, twice at two different temperatures, wherein the temperature difference between a first hot press and a final hot press is set to 50 deg.C or above.

Title: Building up method using laser beam
Inventor: MORI KAZUHIKO
IPC: B23K26/34
Filed: 1985-03-08
Abstract: PURPOSE:To protect the circumference of a build-up part against a laser beam by the bright surface and to prevent the deterioration of the base metal around the build-up by working the circumference of the build-up part to the bright surface having high laser beam reflectivity prior to the irradiation of the laser beam. CONSTITUTION:The build-up part is the surface of a metallic member and the shape thereof is optional such as circular, rectangular, belt-like and annular shapes. A building-up material is generally a metal of the kind different from the base metal and is supplied in the form of powder or bar to the build-up part. The irradiation of the laser beam is executed by an optional method using a laser beam processing machine. Electrolytic polishing, machining, etc. are used for working the circumference of the build-up part to the bright metallic surface and the surface is finished to about the extent at which the laser beam can be efficiently reflected. The beam diameter is determined at such a size at which the beam does not protrude from the bright metallic surface. The build-up part is therefore protected against the laser beam by the bright surface and the irradiation of the laser beam only to the build-up part is made possible.

Title: Aligner
Inventor: TANIMOTO SHOICHI
IPC: G03F7/20
Filed: 1988-02-29
Abstract: PURPOSE:To reduce speckle by dividing a laser beam into two parts, rotating the one of them by 90 deg. in respect to the travelling direction, overlapping the two beams coaxially or in parallel, and constituting this beam so as to be used for illuminating an original plate. CONSTITUTION:A beam of S polarization component reflected by a polarization beam splitter 8 is reflected by mirrors 4, 5 and reflected by a polarization beam splitter 6. Then it enters an optical system 11 which uniformizes luminous intensity. A beam of P polarization component which has transmitted through a polarization beam splitter 3 is reflected by mirrors 7, 8, 9. Since the mirror 7, 8, 9 are rotated 45 deg., in a body, on an optical axis Cl, the shape of a beam reflected by the mirror 9 is rotated 90 deg., and the polarization palne also is rotated 90 deg.. Therefore by arranging a 1/2 wave length plate 10 between the mirror 9 and the beam splitter 6, a beam 15 becomes P-polarization, which is coaxially overlapped with a S polarization beam 14 and enters the optical system 11. A light flux emitted from the optical system 11 illuminates a reticle R with a uniform intensity via a reflecting mirror 12 and a condenser lens 13, and a projection lens 7 forms a pattern image on a photosensitive layer on the upper surface of a wafer W. Thereby, the image quality of a projected pattern can be equal in the longitudinal direction and the lateral direction.

Title: Automatic speed change gear control device
Inventor: KOSHIZAWA TOSHIBUMI
IPC: F16H59/70
Filed: 1989-02-28
Abstract: PURPOSE:To perform proper shift down by a method wherein a descending engine brake state at the same step is detected, and from an overrun decision car speed set at each step to a value higher than that of a shift down schedule and an actual car speed, shift down to a minimum step at which on overrun occurs is effected. CONSTITUTION:On the assumption of a descending period, a shift down car speed being high only in an idle state is set, so that overrun is prevented from occurring, and a car speed during completion of gear shifting is prevented from a decrease on a flat rod and on an ascending road. When an output state of an accel pedal stepping-on amount sensor 9a is continued for a specified time, it is detected as a descending engine brake state. In this case, if the step is the same, a speed change gear 4 is controlled so that shift down to a step at which no overrun of an engine occurs when shift down from a current step is effected as an overrun decision car speed during idle shift down operation set at each step is compared with an actual car speed detected by a car speed sensor 8.

Title: Reference voltage generation circuit
Inventor: SUMI TATSUMI
IPC: G05F3/24
Filed: 1990-02-28
Abstract: PURPOSE:To reduce power consumption and to make immune from the fluctuation of load power by permitting a bias circuit to provide the bias to a source follower output stage, and to negative-feed back the output voltage of the source follower output stage to the bias circuit. CONSTITUTION:Transistors QN1 and QP1 constitute the source follower output stage and transistors QP3 and QN3 constitute the bias circuit. A bias voltage VM taken out from a connection point between the drain of the transistor QP3 and that of the transistor QN3 in the bias circuit is impressed on the gates of both transistors QN1 and QP1 of the source follower output stage. The output voltage VRF of the source follower output stage is fed back to the gates of the transistors QP3 and QN3 constituting the bias circuit by a negative feedback route NFB. Thus, a stable reference voltage can always be supplied even if a load current is changed and a complementary semiconduc tor integrated circuit can stably be operated and it can be made highly precise.
