Title: Swash plate type axial plunger rotating device
Inventor: TAKAHASHI NORIYUKI
IPC: F04B1/20
Filed: 1978-12-28
Abstract: PURPOSE: To prevent the leakage of working fluid at a relatively moving and contacting part by filling fluid having pressure higher than the pressure of low pressure fluid and lower than the pressure of high pressure fluid in a fluid closing chamber between a cylinder block and a sealing enclosure.  
     CONSTITUTION: When a hollow driving shaft 5 is rotated relatively to a sealing enclosure 1, a cylinder block 7 also rotates relatively to the enclosure 1 and a distributor plate 25 and each plunger 9 reciprocates along a regulating swash plate 18. Working oil pressurized in the motion is sent to high pressure fluid passages 31 and 32 via a high pressure fluid groove 29 while working oil returning to low pressure fluid passages 30 is sucked into cylinders 8 via a low pressure fluid groove 28. During the time, the short amount of working oil is supplied via a hollow hole 34 and a check valve 33 into the high pressure fluid passage 32 and working oil in a fluid closing chamber A is maintained to always keep appropriate pressure by the action of a pressure adjusting valve 35, and thus leakage through the contact surface between the block 7 and the distributor plate 25 is prevented.

Title: Cathode material for electrolytic capacitor
Inventor: TAMAGAKI HIROSHI
IPC: C23C14/06
Filed: 1990-06-22
Abstract: PURPOSE:To increase electrostatic capacitance by surfacing a base material with a film consisting mainly of a conductive metal nitride. CONSTITUTION:Surfacing a base material with a vapor deposit of a conductive metal nitride represented by TiN suppresses oxidation progressing on a film surface much more than in the case of a pure metal film because a film-forming metal element has already compounded with nitrogen; consequently, a natural oxide film can be formed as thin as possible and it follows that a high electrostatic capacitance can be obtained. In addition, the surface of a metal nitride film is dotted with numberless fine irregularities of 0.1-0.3mum having square form, so as to contribute to improvement in electrostatic capacitance from viewpoint of enlargement in surface area.

Title: Recorder
Inventor: KOBAYASHI YOSHIKAZU
IPC: H04N5/91
Filed: 1982-09-22
Abstract: PURPOSE:To reduce crosstalk and jitter for reproduction, by synchronizing the phase of the FM frequency of a certain part, at least, of a periodic signal with that of a synchronizing signal when a time series signal having the synchronizing signal is subjected to FM modulation and is recorded. CONSTITUTION:Though the output of an FM modulator 29 is a normal FM frequency, the synchronizing signal period of this output is removed by an NAND gate 39. Outputs of NAND gates 36, 34, and 39 are impressed to an NOR gate 35, and a desired FM signal where the FM frequency of the synchronizing signal part is synchronized with a subcarrier signal FSC is obtained as the output, and this FM signal is recorded on a video disc in a form of one round/one frame; and in this case, bits are arranged radially with respect to the synchronizing signal period. Thus, since bits 24 in synchronizing signal parts between adjacent tracks have the same phase and are arranged accurately, there is a very little probability that crosstalk and jitter occur at the reproducing time.

CONSTITUTION:When a call comes from a telephone line L, facsimile equipments F1-F3 detect a call signal by a call signal detection circuit 2 to count the number of arrival of the call signals, when the count is coincident with the setting value of the incoming call number of the facsimile equipment F1, the facsimile equipment F1 revises the setting value to a maximum value and its control section 3 sets a control signal S1 to close the telephone line L by a closing circuit 1, thereby starting the facsimile communication. In this case, the control section 3 of the facsimile equipments F2, F3 uses a line closing signal S3 of the line closing detection section 5 to decrement the setting value by 1, thereby advancing the reception order. Thus, the number of times of reception of each facsimile equipment is averaged and lots of facsimile documents are received with a low cost.

Title: Constituting system of optical time division multichannel
Inventor: MATSUNAGA TOORU
IPC: H04B10/00
Filed: 1983-09-10
Abstract: PURPOSE:To make time division multiplexing, demultiplexing, and switching of optical signals as it is possible without converting them to electric signals by using an optical bistable circuit as a speech memory. CONSTITUTION:An optical bistable circuit Bi emits light if there is an intermediate output holding input in a terminal 4i when an optical signal is inputted from a terminal li; and as long as there is the intermediate output holding input in the terminal 4i, the circuit Bi continues to emit light even if the optical signal input to the terminal 1i disappears. An optical gate Gi outputs the optical signal inputted from a terminal 2i to a terminal 3i by a control signal from a terminal 2i. When the output to the terminal 3i is terminated and light emission of the optical bistable circuit is unnecessary, the input of the terminal 4i is extinguished to stop light emission. Presence/absence of the input light to the terminal 1i is stored as I/O information in the optical bistable circuit, and the optical gate is switched a little after to take out I/O information as an output light. Optical signals of highways HW1-HWn are inputted from respective input terminals 11-1n of memories M1-Mn and are stored in bistable circuits Bi-Bn and pass gates G1-Gn, which are switched with time shifts, and are outputted to output terminals 31-3n. Optical signals of terminals 31-3n are coupled with one another by an optical coupler C and are outputted to a time division multiplex highway from an output terminal 6.
