Title: Ink discharge detection method for ink jet pump
Inventor: INAGAKI KAZUYUKI
IPC: B41J2/175
Filed: 1985-01-14
Abstract: PURPOSE:To detect an ink discharge accurately and easily by detecting a discharge amount from a drive value within a prearranged time based on the relationship between a prearranged piston drive value and an ink discharge. CONSTITUTION:If a start signal for ink discharge measurement test is input, an ink pressure is once set at proper level and then a measurement time is set at preset time. The measurement time is sequentially subtracted until it reaches zero by synchronizing said time to a driving signal of a stepping motor 2. In the meantime, the motor 2 is driven so that a detection pressure may be kept at proper level by a sensor 28, and counts the number of driving pulses while correcting them at BCD. If the measurement time reaches zero, the number of pulses counted is indicated and an ink discharge at the time of measurement is sought based on the relationship between the number of pulses premeasured at normal time and an ink discharge. Thus, any generated ink clogging is checked and resultantly an ink discharge is detected correctly.

Title: Hybrid integrated circuit device
Inventor: KATO HAJIME
IPC: H01L25/04
Filed: 1990-01-11
Abstract: PURPOSE:To facilitate the positioning of a lead frame by lifting up a heat radiating body in a degree that a lead is not in contact with the heat radiating body, inserting an insulative spacer between insulating substrates, and constituting a space between the heat radiating body and the insulating substrate. CONSTITUTION:Since a semiconductor element 6 is mounted on an insulating substrate 6, the temperature rise is large, so that heat dissipation must be increased by boding an Al heat sink 4 with solder 9. However, there are no large heat radiating bodies on a thick film substrate 2, so that perfect bonding to the Al heat sink 4 is not necessary. Hence when an insulative spacer 11 is inserted between the thick film substrate 2 and the Al heat sink 4 and bonded with an adhesive 5, a clip lead frame 10 can be used. Further, by utilizing the space between the thick film substrate 2 and the Al heat sink 4, an electronic parts 8 can be mounted.

Abstract: PURPOSE:To make it possible not to generate wrinkles on a decorative sheet and to bring always good adhesion between the decorative sheet and a laminated base material when the decorative sheet is bonded on the outer surface of the laminated base material by means of vacuum laminate molding. CONSTITUTION:The pressure of the second chamber B is kept a little higher than the pressure of the first chamber A by making the vacuum of the second chamber B less by a specified value than the vacuum of the first chamber A and a decorative sheet S is expanded thereby into a spherical face shape by expanding the decorative sheet S to the first chamber A side due to the pressure difference. The decorative sheet S is at first brought thereby into contact with the central part of a laminated base material W at its apex of the expanded part. Thereafter, on the process where the decorative sheet S is adhered on the laminated base material W, there is no possibility that the transverse movement of the decorative sheet S to the laminated base material W is restricted and wrinkles are generated when the decorative sheet S is bonded on the outer surface of the laminated base material W.
