Title: Da converter
Inventor: NAKAMURA YASUYUKI
IPC: H03M1/74
Filed: 1986-12-24
Abstract: PURPOSE:To obtain a DA converter with high linearity by correcting the fluctuation of the bias condition of a control element being a component of the DA conversion section depending on the input digital quantity. CONSTITUTION:When a 1st output current supplied to the 1st output terminal 3 is changed in response to the digital quantity inputted to the DA conversion section 1, the potential at the output terminal 3 is changed. Thus, the bias condition of the control element connected to the 1st output terminal 3 among the control elements being components of the DA conversion section 1 is changed to change the current flowing to the control element. A 2nd output current outputted to a 2nd output terminal 4, however, is changed in the opposite direction to the 1st output current at the same time and the potential of the 2nd output terminal 4 is changed in the opposite direction to the potential of the 1st output terminal 3. A bias voltage applied to the control element of the DA conversion section 1 from the bias circuit 8 by the change in the potential at the 2nd output terminal 4 is changed in a direction to compensate the current change to the control element connected to the 1st output terminal. Thus, the DA converter high accuracy and linearity is obtained.

Title: Sealing system for rod
Inventor: NAKAMURA TAKAAKI
IPC: F16J10/00
Filed: 1986-12-27
Abstract: PURPOSE:To prevent deformation of any sealing component, by supplying a pressure from the outside of a cylinder into a hole which is made in a seal holder to reduce a relative pressure applied on the sealing component. CONSTITUTION:An opening 11 is formed on an inside wall surface near the center position between a recess 4 and a recess 5 made in a seal holder 1 and also a hole 13 opened to the outside of a cylinder 10 is formed. The hole 13 is connected to a pass 14 and the pass 14 is connected to a tank 16 through a pump 15. Therefore, a pressure difference occurs between seal components, namely a seal 7 and a U ring 8. Consequently, if the cylinder room side of the seal 7 is pressurized following the pressure rise in a cylinder chamber A, a pressure supplied from the outside of the cylinder is added to the cylinder edge side of the seal 7, then the relative pressure applied on the seal 7 is reduced and deformation of the seal 7 is prevented.

Title: Tracer memory control circuit
Inventor: YAMAZAKI ATSUSHI
IPC: G06F11/34
Filed: 1988-12-08
Abstract: PURPOSE:To store only effective trace data by storing the counted value of a counting means as well together with the trace data to a trace memory. CONSTITUTION:When the condition of an FF 6 is 0, an address counter 7 is made incremental synchronously with a system clock. However, when the condition value is 1 and only when a microinstruction is executed, the count is made incremental and in the other case, the count is in a hold condition. Accordingly, the same address of a tracer memory 10 is still shown and trace data 4 are overwritten to the memory 10. While the condition value of a WATT signal 3 is 1, a counter 9 is made incremental synchronously with the system clock and when the condition value goes to 0, the counter 9 is reset. By adding the counter 9 to the trace information of the memory 10, it can be known of which clock the signal 3 is outputted before the microinstruction is executed. Then, the effective data can be stored to the memory 10.

Title: Liquid-cooled projection cathode-ray tube device
Inventor: WAGAMITSU YASUHIKO
IPC: H01J29/86
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a projection image whose resolution and contrast are stabilized over a long period by disposing a hermetical space formed inside a projected part ahead of a hermetical space formed between a face plate and a transparent plate. CONSTITUTION:Heat generated in a phosphor 8 is transferred to a heatradiating spacer 11 by convection via a liquid 7 from a face plate 2, and it is radiated outside from the surface. Hence, a temperature rise of the face plate 2 is suppressed, and input power can be increased so that a projection cathode-ray tube 1 can be made to become luminous in high brightness. On the other hand, the filled liquid 7 gradually penetrates through portions of adhesives 12 and 13 in proportion to an operating time of the projection cathode-ray tube 1. An air layer 18 is generated equivalently to the penetrated part of the liquid 7 and it is gradually increased. Since specific weight of the air is smaller than that of the liquid, the air layer 18 does not stagnate in the vicinity of the transparent plate 5 but moves to a hermetical space 15, and so it does not appear inside the effective screen of the projection cathode-ray tube 1. Therefore, since refraction and reflection of light do not occur in the air layer 18 inside the effective screen, the projective image can be prevented from being deteriorated in its focus and lowered in its contrast.
