Title: Ink jet recording head
Inventor: MORI TOSHIHIRO
IPC: B41J2/19
Filed: 1988-06-21
Abstract: PURPOSE:To effectively execute removal of air bubbles in circulation and recovery modes by forming the ceiling, sidewalls and connector of a liquid chamber above the opening of a connection hole of curved faces crossing the opening of the hole to the inside of the chamber. CONSTITUTION:A curved face 16a continued from the sidewall of a liquid chamber 16 to its ceiling to cross the openings of connection holes 15a, 15b in the direction of the inside of the chamber 16 is formed above the openings of the holes 15a, 15b. When operations in recovery and circulation modes are conducted by providing the structure of such a chamber 16, ink supplied, for example, from the hole 15a is guided to the face 16a to be smoothly fed without staying inside the chamber and to arrive at the other hole 15b. In this case, if air bubbles are stayed in the chamber 16, they are caught by the flow to be effectively discharge from the hole 15b, thereby always conducting good air bubble removing operation.

Title: Laser diode device
Inventor: FUJINE NOBUHIKO
IPC: H01S5/20
Filed: 1983-08-19
Abstract: PURPOSE:To make sure the sufficient connection of a P<+> layer, which must originally connect an anode electrode and a P type AlGaAs layer on an active layer, by forming a pair of electrodes to a semiconductor layer having the same conduction type as the active layer in which a striped semiconductor layer is buried. CONSTITUTION:N<+> layers 11a, 11b for conducting an N type GaAs layer 5 and electrodes 12a, 12b are formed in parallel on both sides of a P<+> striped layer 6. When voltage is applied between the electrodes 12a and 12b, currents do not flow between both electrodes when the P<+> layer 6 completely reaches to a P type AlGaAs layer 4. When the P<+> layer 6 does not reach to the P type AlGaAs layer 4, however, currents 13 flow when voltage is applied between the electrodes 12a and 12b. Accordingly, the sufficient depth of the P<+> layer can be detected by investigating the conditions of conduction between a pair of the electrodes formed on the N type AlGaAs layers buried on both sides of the P<+> layer.

Abstract: PROBLEM TO BE SOLVED: To moor a cable core and prevent its slip-down even in the case of the vertical laying or the inclined ground laying of a power cable by winding a cushiony tape around the cable core with the same pitch as the corrugation pitch. SOLUTION: On the periphery of an extra-high voltage power cable core 1 a cushiony tape 3 is lap-wound with the same pitch as the corrugation pitch of a metal sheath 2 covered thereon. That is, the cushiony tape layer 3 is formed by lap-winding a following cushiony tape 3 on the previously wound cushuony tape 3. The metal sheath 2 is covered so that the corrugation root portions of the metal sheath 2 are positioned on the lap-wound cushiony tape layer 3. Thereby, such a cable core slip-down prevention type power cable is obtained as allowing no formation of a mechanical and electrical stress concentration portion resulting from the local oppression of the metal sheath 2 to the cable core 1.

Filed: 1992-05-19
Abstract: PURPOSE:To provide a semiconductor integrated circuit device equipped with an output circuit which effectively suppress noise generation without increasing the circuit scale by inserting an MOSFET which operates substantially as a resistance element in a high-voltage range into a driving stage circuit. CONSTITUTION:The MOSFET 3 which operates substantially as the resistance element in the high-voltage range with the output signal of a voltage detecting circuit VGEN detecting a source voltage being held above a specific voltage is inserted into the driving stage circuit DRV1 to prevent a driving signal which is supplied to the gate of an output MOSFET 6 from increasing. Consequently, the resistance value of the resistance element increases in inverse proportion to the rise in the source voltage to limit the increase of the driving current without increasing the circuit scale of an output buffer, so effective noise reduction is possible.
