Title: Mobile communication equipment
Inventor: MATSUDA AKIKAZU
IPC: H04B1/38
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce background noise and to obtain satisfactory radiation characteristic by providing a slit in an area to connect to first and second ground conductors so as to reduce a current in the periphery of a control circuit part on a printed circuit board. SOLUTION: A slit 20 is formed in the area of a ground conductor 14 to connect a radio circuit part ground connector 12, which constitutes the first ground conductor, with a control circuit part ground conductor 13, which constitutes the second ground conductor. These ground conductors 12 to 14 are integrally arranged on the printed circuit board 5 as one board body and connected with one another. As a current flowing in a longitudinal direction through the ground conductor 12 of the board 5 is interrupted by the slit 20 to flow in a lateral direction near the slit 20, the route of the current is extended to sufficiently attenuate and as the width of the ground conductor 14 is small, the current flowing in the longitudinal direction through the board 5 is suppressed. Consequently, the current in the periphery of control circuit 7 on the board 5 is reduced.

Title: Magneto-optical recording medium
Inventor: SHIMIZU SHOJI
IPC: G11B11/10
Filed: 1990-09-17
Abstract: PURPOSE:To improve recording sensitivity characteristics and signal quality by using an SixN1-x film having a small thermal conductivity and large refractive index as an intermediate layer. CONSTITUTION:The intermediate layer 2, a magneto-optical recording layer 3 and a protective film 4 are successively formed on a substrate 1. The SixN1-x film having the concn. of N lower than the stoichiometric compsn. is used for the layer 2, a TbFeCo alloy for the film 3 and stoichiometrical Si3N4 for the film 4, respectively. The refractive index (n) increases when the concn. of the nitrogen decreases and, therefore, a sufficient enhancement effect is expected. An attenuation constant (k), however, increases with an increase in the refractive index (n) and, therefore, the absorption of light in the magnetic film decreases or there is the possibility that an adverse influence arises in the medium characteristics, such as increase of noises. The recording sensitivity and signal quality are, thereupon, improved by using the material consisting of the compsn. having small x=0.016 is used as the intermediate layer.

Title: Retrial control system
Inventor: FUJIKI MASAKI
IPC: G11B20/18
Filed: 1983-12-29
Abstract: PURPOSE:To improve a success ratio of retrial and to reduce the number of retrials by controlling a selection output means, outputting reproduction data of the other reproduction head, and executing the retrial when the error exists in the reproduction signal. CONSTITUTION:Data which are read from a read head R1 are reproduced by a data regeneration circuit 5, and the presence or absence of an error is checked by an error check circuit 6. When the error is not detected, the data are read as they are. However, when the data which are read by the read head R1 have the error, the error check circuit 6 detects the error, and outputs the error signal. Thus, the switching signal is outputted for a control circuit 1 and an analogue switch 2. Thus, the analogue switch 2 executes output switching control and outputs the input signal from a read preamplifier 4. Therefore, the data which are read from a read head R2 are outputted from the analogue switch 2, and they are transmitted to the data reproduction circuit 5.

Title: Absorption refrigerating machine
Inventor: TAKIGAWA TAKATOSHI
IPC: F25B15/00
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To improve the coefficient of performance COP of an absorption refrigerating machine. SOLUTION: An evaporator 1 and an absorber 2 forming a double effect absorption cycle 10 are formed in a multistage. In a low pressure side absorber 14, absorbing solution of high concentration is used at relatively high temperature, so that the crystallization of absorbent can be avoided. In a high pressure side absorber 13, the concentration of the absorbing solution is relatively low, so that the concentration range from the inlet side to the outlet side of the whole part of the absorber 2 can be increased. If the temperature difference between the inlet side and the outlet side when cooling water is cooled by a cold and hot water pipe 15 from a high pressure side evaporator 11 to a low pressure side evaporator 12 is higher than rated 5 deg.C, the coefficient of performance COP can be more improved.

Title: Four-value fsk receiver and signal discrimination method therefor
Inventor: TADA KENICHI
IPC: H04L27/14
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent code errors from being generated even when the amplitude of a demodulation signal is changed by restoring the reference value to be a correct value in a short time, even when an erroneous value is set as the reference value so as to follow a small fluctuation in the demodulation signal. SOLUTION: When a received 4-value FSK signal is converted to a 4-value digital code, a mean value circuit 12 calculates a mean value of a demodulation signal 3, and the processing of increasing/decreasing overall the value of a digital signal is always conducted stepwise in a waveform shaping circuit 13, so that the mean value is a 2nd reference value. Thus, the effect of the fluctuations in the median of the demodulation signal 3 is reduced. A reference value generating circuit 14 revises the 1st and 3rd reference values, based on levels denoted by codes '10', '00' in the digital signal to reduce a code error caused by the effect of a change in the amplitude of the demodulation signal 3.

Title: Variable frequency voltage-controlled oscillation circuit
Inventor: TAMURA MASAHIDE
IPC: H03C3/22
Filed: 1983-12-26
Abstract: PURPOSE:To stabilize modulation sensitivity which is generated when a DC voltage signal for phase locking varies in voltage value over a wide range by superposing part of the DC voltage signal for phase locking upon a modulating signal. CONSTITUTION:A variable reactance circuit 2 is so constituted that a DC signal terminal APC.IN for phase locking is grounded through the series voltage dividing circuit of resistances R1 and R2 and the voltage division point 4 is connected to a modulating signal input terminal MOD.IN. Consequently, a part of the DC voltage signal APC for phase locking which varies in voltage value over a wide range is superposed upon said modulating signal MOD to apply at DC bias to a varactor diode D2 for modulation, so the extent of variation in capacity value between the varactor diode D2 and a varactor diode D1 of phase locking follows up the value of said voltage signal APC in necessary correlation. Consequently, the modulation sensitivity is made constant.
