Filed: 1985-10-18
Abstract: PURPOSE:To prevent a user from leaving a line held erroneously or leaving a call held by performing the holding operation independently of the service state to send a holding tone from the speaker of a telephone set. CONSTITUTION:When a holding switch 16 is operated for the purpose of setting the holding state, a holding tone generating circuit 19 is operated to set the holding state, and switches 7 and 21 are turned off and on respectively and a transmission circuit of a loudening speaking circuit 11 is muted by a control line 18b. The holding tone generating circuit 19 sends the holding tone to the line through a holding tone sending circuit 17 and inputs it to the loudening speaking circuit 11 through a holding signal line 10. In a telephone set circuit, all operations are performed by a local power source and the service of the telephone line is set to the holding state independently of the service state of a handset speaking circuit or the loudening speaking circuit, and the holding tone is sent not only to the line but also from the speaker of the telephone set.

Patent JP-S6384951-A (JP)
Title: Thermal printer
Inventor: TAKAGI KAZUHIKO
IPC: B41J2/36
Filed: 1986-09-29
Abstract: PURPOSE:To perform sharp printing regardless of horizontal or vertical writing by providing a control means to change printing energy supplied to a printing element at the time of vertical writing to a lower level than when horizontal writing starts. CONSTITUTION:If a horizontal writing mode designation key 11 is operated, a mode designation signal SG1 is output, and a latch circuit 20 maintains the output signal at low level. Then CPU 13 outputs a drive signal SG2. In addition, a timing circuit 21 of a printing energy setting circuit 19 outputs head drive signals SG6, 7 respectively. In the meantime, if a vertical writing mode designation key 12 is operated, the latch circuit 20 maintains the output signal at high level. This results in the output of a signal SG4 synchronized with the head drive signal 7 for a vertical writing pulse generation circuit 23 from a NAND circuit 27. Consequently, a printing element is heated in response to the drive signals SG2 and SG4, and the printing energy turns to a low level because the pulse width of SG7 at the time of vertical writing mode is set narrower than that of SG6 in horizontal mode.

Title: Thin film magnetic head
Inventor: YONEDA HIROSHI
IPC: G11B5/31
Filed: 1983-12-13
Abstract: PURPOSE:To obtain a thin film magnetic head having extremely excellent driving performance by incorporating specific particles into an adhesive which is used for adhesion of a protecting plate. CONSTITUTION:For an adhesive containing carbon particles, the fine carbon particles separated from the adhesive are distributed over the entire rubbing surface of a magnetic head in response to the drive of a medium. This produces the lubricant effect and improves greatly the driving performance of the head. The output variation characteristics shown by a solid line in the figure show the initial driving value. While the output drop characteristics shown by a broken line show the difference between output levels obtained after the 10hr driving and in the early stage of driving. The output variation is reduced down to <=1dB with the output drop due to driving set at <=2dB respectively. In such a case, it is desirable to set the amount of carbon at a 2-30% range together with the particle diameter of carbon particle set at 0.06-20mum. The driving performance of the head is also improved by mixing the abrasive particles having the same wt% as the carbon particles into the adhesive. The higher lubricant effect is secured by setting the adhering area at a place closer to the feed side of the medium than the head part in terms of the driving direction of the medium.

Filed: 1991-09-13
Abstract: PURPOSE:To prevent the generation of noise by forming the journal shaft of a ceramic turbine in the shape of a polygon in cross section having at least nine corners or more or a shape having nine or more protrusions and recessed parts. CONSTITUTION:A ceramic turbine rotor 1 and a compressor rotor 3 are interconnected through a metallic shaft 2. When the number of corners and the number of crests of the polygonal shape in the shape of roundness of a journal shaft is high, it is considered that the protrusion and the recessed part are changed in a delicate manner and the change in a pressure of an oil film does not follow and vibration is not generated. To form the shape, provided the number of revolutions of the journal shaft 4 is A and the number of revolutions of a grinding wheel is B, grinding is effected on a condition to satisfy a formula of B/A>=9. This method provides a ceramic turbocharger which is prevented from the generation of vibration during an actual use and the generation of noise owing to vibration.

Abstract: PROBLEM TO BE SOLVED: To provide a data processor which can read data out of a device that can reply only to the data read request of 1 or 2 bytes even when an MPU which issues a data read request equivalent to the largest port size is used in a data read access mode. SOLUTION: This controller decides whether the access of an MPU 20 is a read access as long as the access address of the MPU 20 is included in the set value of the upper and lower limit address setting registers 3 and 4 and the set value of a byte read access enable register 9 is effective. If a read access is decided, a byte read access byte enable signal 12 is outputted to the target devices 21 and 22 as a byte enable signal 33 respectively. If the access address of the MPU 20 shows a write access, an MPU byte enable signal 30 is outputted as the signal 33. Even when the access address of the MPU 20 is excluded out of the set value of both registers 3 and 4 or when the set value of the register 9 is not effective, the signal 30 is outputted as the signal 30.

Abstract: PURPOSE:To facilitate centering and to improve shaving accuracy by freely holding a punch in (x) and (y) directions with a thrust bearing, forming the tip part of the punch to warhead shape and constituting a die so as to be along a small hole in a material. CONSTITUTION:At first, at the time of lowering an upper die 1 in a die-set, the tip part 4a of punch 4 is inserted into the smaller hole 10a in the material 10 whose tip part is placed on the die. At this time, since the punch 4 is freely moved in the (x) and (y) directions with the thrust bearing 5 and the tip part 4a is formed like the warhead shape whose tip part is protruded, the punch is guided with one side of inclined face abutted on the edge of the hole 10a of the work, and the punch 4 receives horizontal component and is shifted in the horizontal direction. By balancing with the horizontal component, the centering is completed. Therefore, since the center of the punch 4 is automatically matched with the center 10a of material to be shaved, the centering is facilitated, and while holding shaving accuracy, the reduction in cost of the installation is contrived.
