Abstract: PURPOSE:To realize the phase stabilizing method which requires no use of a gaseous pressure control device, etc., by enclosing tightly the gas into a semigap type insulated coaxial cable having a positive changing modulus of electric length caused by the change of temperature and stabilizing the phase by the change of the dielectric constant caused by the temperature change of the gas. CONSTITUTION:The gas is enclosed tightly into a semigap type insulated coaxial cable A having a positive changing modulus of electric length caused by the change of temperature. Thus the phase is stabilized by the change of the dielectric constant due to the temperature change of the gas. For instance, the cable A consists of an inner conductor 1, a spiral insulator 2 and an outer conductor 3 respectively. For such cable A, the space factor of the insulator 2 is selected so that the electric length changing modulus is set at +3X10<-6>/ deg.C when the pressure of a gap part 4 is set at a normal level. Then the part 4 is shielded from the outside air by line terminal sealing parts 5 and 5, and the dry air having the gauge pressure of 1.0- 2.5kg/cm<2> is enclosed into the part 4.

Title: Time signal mechanism for clock
Inventor: NAKAMURA NORIHIKO
IPC: G04C21/04
Filed: 1979-08-22
Abstract: PURPOSE:To prevent mishearing in the regular time tone by prohibiting a warning tone to be given before the regular time tone with a warning action arranged prior to the start of the regular time signaling. CONSTITUTION:When the time approaches 59min and 50sec in reading, with the rotating of an hour cam wheel 18, a rockable lever 20 moves falling to the tip 22a of a cam projection 22 and turns it counterclockwise, releasing the pressure of a counting lever 34 by a pin 30. Consequently, the counting lever 34 turns clockwise having the projection 38 thereof engaging a corresponding tooth of a rack gear 40a of a comb teeth 40. At the same time, released from the pressure retention by a pin 32 of the lever 20, a warning tone control plate 10 gets in contact with a warning tone control contact plate 12 to effect a warning tone action. When the time is at zero minute and zero second, a minute cam 58 gets in contact with an engaging member 64 of a 1 minute control lever 60, moving the lever 60 clockwise and a  working member 66 is separated from the contact plate 10 so that it gets in contact  with a time signaling control contact plate 16 whereby a time announcement is  performed. Thirty minutes before the start of warning action, the projection 38 of  the counting lever 34 prohibits the warning action without releasing the comb teeth  40 completely whereby only time signaling action is performed.

Title: Solid-state image sensing device
Inventor: AZUMA MASAMICHI
IPC: H04N5/357
Filed: 1990-04-23
Abstract: PURPOSE:To restrain a signal charge from being left and to enhance a transfer efficiency especially at a high-speed transfer operation by a method wherein a transfer part which transfers the signal charge is constituted of a charge- coupled element whose film thickness in the transfer direction becomes partly small at an effective gate oxide film under a transfer electrode in a transfer region of one conductivity type. CONSTITUTION:An SiO2 insulating film 3 under a transfer electrode in a transfer region of one conductivity type in a charge transfer part is formed in such a way that its film thickness in the transfer direction is made partly small; a channel potential distribution under individual transfer electrodes 4 to 8 is controlled. By this constitution, when the electrodes 4, 5 are set to an ON state and signal charges exist under the electrodes 4, 5, the electrode 6 is set to an ON state. Then, the signal charges are spread under the electrodes 4 to 6. When the electrode 4 is set to an OFF state, the charges are moved under the electrodes 5, 6. When this operation is repeated, the charges are transferred by a four-phase drive operation. Especially at a process to set the electrode 4 to the OFF state, the channel potential distribution becomes low in the transfer direction, and the charges are transferred in a state that they are not left.

Title: Forward extrusion forging method
Inventor: MAEDA TOSHIO
IPC: B21J5/06
Filed: 1985-05-21
Abstract: PURPOSE:To position a billet to the center of an extrusion molding die and to prevent the generation of a longitudinal flash by subjecting the billet to hot forging without restraining the intermediate part to form the intermediate part to the same diameter as the outside diameter of extrusion molding and chamfering both ends to the diameter smaller than the outside diameter in a stage before the extrusion molding. CONSTITUTION:The billet 4 is heated and thereafter the top and bottom ends thereof are chamfered by upper and lower dies 7, 8 until the edges over the entire circumference are eliminated while the central part thereof is not restrained. The ends are chamfered to the angle approximately equal to the angle of the guide part 2 of a cavity 3 of a forward extrusion die; at the same time the outside diameter in the non-restrained part at the center is bulged to the size approximately equal to the outside diameter of the forming part 1 of the cavity 3. The billet 4 is thus smoothly inserted into the part 1 of the cavity 3. The extrusion angle thereof and the chamfering angle are approximately equal and the outside diameter in the central part is approximately equal to the outside diameter in the forming part 1. The billet 4 is thus positioned to the center of the part 1 and the uniform clearance is maintained. The generation of the longitudinal flash at the corner on the top end face after the molding is thereby obviated.

With the dot printing head 1 using this core piece 2, eddy current loss is decreased steeply and a number of printed letters per unit time can be increased.
